Updated 11/15/06 **Modding services**

[shimmishim]

Hi guys!

I've added another mod to my list.

I am able to do the following mods for you:

Motherboards

Asus p4p800 deluxe (non) vdroop mod
Asus p4p800 deluxe (non) vdimm mod
Asus p4c800(e) deluxe vdroop mod
Asus p4c800(e) deluxe vdimm mod
Abit IC7-(max2/3) vdimm mod
Abit IC7-(max2/3) vdimm stabilization mod
Shuttle AN50R vcore mod
Shuttle AN50R vdimm mod
DFI Ultra Infinity vdimm mod
DFI Ultra Infinity vcore mod
EPoX 8KDA3J/+ vcore mod
EPoX 8KDA3J/+ vdimm mod
Abit NF7-s vdimm mod
Abit NF7-s vtt mod
Abit NF7-s vdd mod


I can pretty much do any mods as long as you can show me a picture of the chip that needs to be soldered to...

Video Cards

ATI 9700 PRO vmem mod
ATI 9700 PRO vcore mod
ATI 9800 PRO vmem mod
ATI 9800 PRO vcore mod


Power Supplies

Any Antec True Power or Control series
Any PSU with a 3.3, 5, or 12 volt sense line


If you have any questions, feel free to PM me or IM me at shimmishim or jsohhinm or email me at:

johnshim AT johnshim DOT com
hongshim AT uiuc DOT edu
johnshim AT gmail DOT com

I will also guarantee that your hardware will not be damaged while in my possession. Anything that occurs after the mod is done and returned to you is your responsibility.

As for testing, I can test video cards but will not be able to test motherboards w/o processors (I do have a socket A and skt 754 processor but anything else such as 939, 940, or 478 you will have to send me).

And finally for the bad news...
Since these mods are taking up more time to do than I thought and I am running out of VR's AGAIN... I am going to have to start charging slightly a little more (but not a lot more) for my services.

Motherboard mods (any two - vdroop, vcore, vdimm, etc...) = $20
each additional = $1 (basically cover the cost of a VR)

Video card mods (any two - vmem, vcore, vtt, etc..) = $10
each additional = $1 (basically cover the cost of a VR)


So for those that have gotten mods from me before, I will only charge you for shipping still but for anyone else, the above is the going rate. They do include shipping so please understand that I am not making a huge profit.

Thanks for looking!!!

As for payment method, I will take non-cc paypal but will have to charge slightly more for a cc paypal payment. Please, no echeck payments unless you want to wait 3 to 4 days for payment to clear before I ship back.

[shimmishim]

kungfumaster21 has made a request for the p4p800 vdimm and vdroop mod...

hopefully after i get this done, he'll be able to vouch for my work!

[ReDoCeD]

wish you lived in australia dude for sure i would get it done i,m havind probs just to find someone to do my 550 truepower :( do you know of anyone in aus that can mod or does anybody for that matter :)

[shimmishim]

i wish i knew someone in aus that could do it for you...

it's actually not that difficult to do!! :)

all i did was follow the guide over at xtreme and just jumped right in and did it!

[Jojo1971]

can you "mod' my head..i think something's wrong with it..i always think of "new toys" all the time...

[shimmishim]

lol....

yeah just give me $100,000 for a new brain and i think we can get your problem fixed! :D

these are the vdroop and vdimm mods for the p4p800 completed tonight for kungfumaster! :)

[Hawk]

shimmishim,

Very nice job on the mods. :thumb: You like like you take your time and do the work very neatly. :thumbs:

[shimmishim]

hey!!! i have to!!!

it's not my board! and i'm sure kungfu wants it nice and tidy!

[Paragon]

Very nice job shimmishim :rock: I can't stand sloppy when it comes to wiring and yours is some of the best I've seen :thumbs:

Thanks!

ever since I read that you can use IDE cable as wire, life has been SOOOO much easier.

i also found this tip tinner/cleaner from radioshack and man... i don't really have to use solder anymore! :)

[Jim]

Beautiful work shimmshim. I just did the worlds quickest and dirtiest vdimm mod the other night on my P4C800-E. No mobo soldering required.
Picked up the wire grabber from Outpost.com, a 10 and 5k resister from Radio Shack and put it together.

Here's a pic of the grabber on the mobo:

[Jim]

And the full weapons of mass destruction. Insulated before installation of course. ;)

[shimmishim]

lol... i say whatever works!!! :)

but if you ever want a more permanent solution... just let me know! :)

[death metal]

jim, how are you able to clip that? i bought one and can't seem to hit the right leg :(....

shim, what do you mean tinner/cleaner and no more soldering? how to do that?

[shimmishim]

jim, how are you able to clip that? i bought one and can't seem to hit the right leg :(....

shim, what do you mean tinner/cleaner and no more soldering? how to do that?

it's hard to explain...

it's like solder i guess but it coats your whole tip rather than having to use solder...

you then coat the wire with the tinner and put some on the leg of the IC you want to attach the wire to... then put the two together.. and voila! all done! :)

[Jim]

jim, how are you able to clip that? i bought one and can't seem to hit the right leg :(....

shim, what do you mean tinner/cleaner and no more soldering? how to do that?
death metal , Ship that mobo to Shim and he'll fix it up for you. Mine is a more temporary option for benchmarking, and doesn't require permanent modification.
My secret weapon is my wife's reading glasses. Makes the contact point easy to see. Can't believe I just posted this, she laughs her arse off at me when I have them on. :lol: :o

[death metal]

jim, hehehe, nice tip :)...no wonder you hit that dang lil leg correctly...

shim, thanks for the tip as well. i still don't know how to do that but that should be enough info for me. i actually don't know what a "tinner" is but i'll go bust my lazy ass and search on the net.

[death metal]

shim, i did a quick search and came up with this:

(Look at the lower/middle right portion of the page)
http://www.primedistributing.com/Catalog/199.pdf

another:
http://www.surmountinc.com/Qstore/c000005.htm
http://www.computronics.com.au/multicore/ttc/

are they the one that you mentioned, but there is a step about using soldering iron as well so I'm a bit confused...

[Rukee]

tinning is taking the iron tip and coating it in a layer of solder so it has a shinny apearance. It helps tranfer the heat faster. Usually you would melt a bunch of solder on the iron tip then quickly wipe it with a rag and that coats or makes the solder stick to the tip.

For big wire solder connections one would normaly use the solder tip to heat the connected wires to the point they could then melt the solder and the solder would flow thru the wires welding them together, works great for big wires, but for small computer stuff like this you could ruin whatever you are soldering to real quick while waiting to heat everything up. So by tinning the iron and the wire end before you ever get the wire close to were you want to put it, all you need do it barely touch the iron to the spot and it melts right in without alot of heat or time near the board....or so I`ve been told.
Might do a mod or two to my NF7-S.

[NeoShowtime]

Anyone have any idea if the Hercules 9800 PRO volt mods would be the same?? If so, Shim might be getting to play with mine soon.

~Edit.. Might also send my motherboard for some vdimm and droop lovin'. And what exactly did your Tru430 mods do to the rails? and would you be willing to do that to mine? Heheheh.

[shimmishim]

the 9800 can be modded... but i warn you... i'm 1 for 2 on this mod :)

the first time i did it, something was wack with my ground point and the voltage spiked and the card died :(

as for the antec TC mod, it basically allows you to get higher voltage rails...

so when i had my p4p800, i ran my 3.3 volt rail around 3.6 so that i could get at least 3.45 volts to my vdimm...

i also run my 5 at 5.17 and my 12 at 12.3

:)

[shimmishim]

DFI infinity added to list + antec power supplies :)

[jcniest5]

Shimi, can you do mine, too? I just got mine, but am too afraid to use the hot iron so if you can, please possibly do it for me, too? Let me know. For mine, I want all, like the vdroop, vdimm and also vagp.

[shimmishim]

i haven't heard of a vagp mod for the p4p/c 800

the vdimm and vdroop should be no problem.

all i'm gonna require is money for the shipping.

get with my PM. I need your info first.

:)

[Jim]

shim I guess he's talking about the AGP mod found here (http://www.malvescorner.com/p4c800.htm) . But I doubt that one is really necassary. :wave:

[Hawk]

Shimmishim,

What are you using for the soldering tool? Normal soldering iron or something newer. :mischeif:



I just picked up one of these, the Cold Heat Soldering Tool. All I can say is it's freaking awsome. :yup:

http://www.coldheat.com/

[shimmishim]

just a normal 15W soldering iron :)

hm... that looks pretty tight...

how fine is that tip?

and how much was it?

[Hawk]

The unit itself is $19.95 and the tips, there are 3, are $9.95 each. Not too bad. I'll say I can definitly do the mods with it on the small traces. ;)


Plus, it works off of AA batteries. . . :thumb:

[jcniest5]

:)

I'm gonna try it first and see if I can do it. If not, I will PM you my info and we'll go from there.

[shimmishim]

coo coo

i might have to try one of those babies out!

[jcniest5]

I went to two Radio Schack stores and they don't have the VR nor the pots. They have those radio type pot/Volume Control that is so big I didn't buy anything.

Shim, how many have you done so far (excluding your own)? The tip of the iron seems too big to solder those small/tiny contacts. I'm afraid I might spread it and kill my board.

Is it really that hard? Or is it just me thinking it the hard way? :cry:

[shimmishim]

yeah i ordered my 50k VR's from an online vendor.

I've only done 1 other besides mine and that went fine.

What iron are you trying to use?

Honestly, it's not THAT hard. It just takes patience and a steady hand.

[jcniest5]

Yeah, I tried it on a fan and I messed it up. Probably my iron's tip is too big, so when the melting begins, it's too big/wide, so it spreaded to other close by components. Then from looking at the connect pad on the mobo, it's so small (in fact it's really tiny) so that really discourages me! What I did on the fan was much bigger and yet I messed it up, so with this so tiny thing, I'm really scared. :bonk:

[NeoShowtime]

First, try to file down the tip of your iron, make it nice and sharp. Then all I can suggest is try to tin the wire and the iron. That way you can just hold the wire in place and touch it with the iron and its done nice and clean. Also, what type of wire are you trying to use?

[Hawk]

what type of wire are you trying to use?








I hope it's not 14Gague Romex. . . :yikes: :lol: :lol: :rotflmao:

[jcniest5]

I'm going to use the IDE stripped wire for this mod. I haven't gotten the proper VRs or FRs yet, though.

[shimmishim]

good wire ... that's what i use too :)

if you need VR's let me know... i just ordered $15 bucks worth from a vendor (that's the minimum order).

I can sell you some individually if you need them.

i have a supply of

1k
5k
10k
50k
100k

[jcniest5]

Well, I finally had the guts to do the vcore droop on my P4C800-E Deluxe tonight. I tried alot of tests on something else before I finally had the guts to put the wire on the two metal pads and then one by one, managed to put the hot iron to do it. It's working fine now, though I'm not sure how effective the job is. I'm doing Prime95 on my machine. One thing, though, as soon as I run Prime95, my vcore drops from 1.68 to 1.57 and fluctuating back and forth between those two numbers. Before I did the mod, even without running any stress program, my vcore would jumped back and forth between 1.54 and 1.68. By the way, I have a Celeron 2.4Ghz OCed to 3.13Ghz using basic SPD setting in the BIOS. No voltage change of any kind. Everything is at default using 30% OCing and Turbo setting. I'm gonna try to set a certain voltage for the vcore and see if it still fluctuates.

Thanks, guys! Aren't you proud of me? Hehehhehe...LOL :lol:

[shimmishim]

your vcore is fluctuating too much still.

when i did the mod mine was like....

bios 1.65
range 1.75 to 1.58

after the mod:
1.68 to 1.63

your range is still too large

what resistance isyour pot set to.... 27k? 28k?

[jcniest5]

Well, when I was at Radio Schack, they didn't have any small pack of resistors of 27K (so I can connect one 27K in series with one 1K) or the 50K pot, so I bought a 5-pack of 22K resistors and one 10K vr. After connecting one 22K resitor in series to the 10K vr, I adjusted the pot so the reading was at 28K and then soldered or modded my mobo using that setting. Was there something different I could have done to make my mobo work better? Also, does it matter which pin we use? I used the the middle and the bottom pin(fartest from the adjustable screw or pin 1 and 2). Pin 3 is unused.

After the mod was already done, I measured the reading again and it was at 20K, because now I wasn't measuring only the two resistors, but the whole thing, which also involved the resistors on the mobo. Have you tried measuring your work after everything was connected and see what the reading was? Can you try that and let me know what kind of combined reading you get?

[jcniest5]

Further into my mod project and discovery: The mod isn't working. Perhaps I don't have the proper resistors. I tested the mobo more thoroughly and found that the fluctuation is exactly the same way (as before) without the mod. First, I doubted my mod is any good. I traced all the wire I soldered and found that all were connected properly with no broken link. But no matter what I do, the fluctuation is still the same.

I set the voltage in BIOS to 1.60. Fluctuation in MBM is between 1.57 and 1.68. With or without the mod, fluctuation is exactly the same.

Is connecting the two resistors in series (one fixed 22K and one vr 10K) a wrong way of doing it?

What am I doing wrong? :bonk: :beat: :smash:

[shimmishim]

doing it in series like that is fine...

it's a combined 32k.

hmm...

[shimmishim]

once it's connected to the points, it shouldn't be reading 27k.

it should read close to zero if i remmeber...

[jcniest5]

It's terrible! It just doesn't work. I tested to make sure there is continuity through the soldered tip to other series connection surround it and it good. It still fluctuates too much. I set 1.70 in BIOS just to test it. And guess what? It fluctuates all the way down from 1.74 to 1.55. It's not use. I'm going to try the resistor close to the IC and see if that makes any difference. Otherwise, I'm through with this mod thing. :smash:

[shimmishim]

then send it off my way! :)

i'll do it for ya for a very minimal cost!

[jcniest5]

Well, I experimented it almost the whole night last night. I tried resistance of 50K all the way to 10K. The best resistors with the least fluctuation is the 12K and 18K. When using the 12K, it fluctuates between 1.68 and 1.63. When using the 18K, it fluctuates between 1.66 and 1.70. The funny thing is after I decided to go with the 18K, after soldered it securely to the wire and put the mobo back in the case, guess what? There again, it went back to 1.57 - 1.68!!!! :smash:

It seem like the mod isn't working. Its fluctuation seems to be more severe when first start the computer. If I let it run for awhile, it stabilized itself within the acceptable zone. Still not sure if it works properly. It's driving me nuts now. I think I'm giving up on it.

One more misfortune. I did all my PSU mod today and managed to kill my WD0100JB 100GB hard drive. I was adjusting the vr pot and I guess I gave it too much juice and my system shut itself off. When I turned it back on, one of the two HDs is didn't not turn on at all. No power to it at all.

Good thing it's still under warranty, so I'm RMAing it.

[shimmishim]

uhh...

why do you have your hard drives plugged in while adjusting the pots?

i unplug everything before i tweak my pots...

oh well... i'd eat that one up (the dead hard drive) but to each his own...

[jcniest5]

That's the thing I have to swallow. I treaked it while in Windows, using MBM5. I guess I should've done it in the BIOS with nothing attached. What did you set you pot to before turning on the PC? Now, to raise the voltage, do I lower or raise the pots?

Here's the components I used:

3.3V - 10 ohm fixed resistor with 1K vr
5.0V - 33 ohm fixed resistor with 10K vr
12V - 68 ohm fixed resistor with 10K vr

I set them all the way to max before turn on the PC. I checked in MBM5 and the voltage was still low for the 5 and 12 line. That's why I treaked it then suddenly my PC shut down and thus how the dead drive came to rest.

I was afraid I did something horribly wrong, so I took out everything I modded and just reconnect all the wires I cutted. I'm afraid to do it again thinking of the worst thing.

[shimmishim]

i use a voltmeter.

don't use bios don't use mbm5...

use any of the black slots on the atx plug as a ground ...

and then measure the orange wire (3.3)

measure the red wire (5)
measure the yellow wire (12)

or the 5 and 12 may be reversed.

yeah... that's the proper way to do it.

so far... i haven't killed hardware due to the tweaking my power supply.

[jcniest5]

Thank goodness, I was able to do the mod this time without plugging in any device and measuring the lines before plugging the rails. It's funny, though. On the 12V line, I get 12+ reading on my voltmeter, but in the MBM5, I get like -.60 to -.80 less than what I get with the voltmeter. I get 12.35 with the voltmeter and I get 11.67 in MBM5. Which reading is correct? I'm confused!!!!! :scratch:

[death metal]

oh, sad to hear you broke your HD....but it's nice to see you're trying to learn...like shim said, if you've got too much prob, shim can do it for you...

[Ice]

You have a PM, shimmishim! :wave:

[flexkill]

shim it's me, sorry i didn't respond sooner but i decided to do the mod myself. i have to learn how, and this is the only way. i really am grateful of yur time and effort. i think yur work is great and can only hope mine comes out half as good as yur's. what you do, and what you do it for.....if you ask me best deal in the world. you need to charge just a little man, you need something for yur time and skill's. anyway thanx. :bow: :bow: :bow: :wave:

[shimmishim]

:)

glad to hear you did it yourself. i figure if i can get established enough then maybe i could charge but since BE isn't that HUGE like anandtech or xtremesystems or pcperspective... i should try to get my name out first! :)

anyway, if you need any trouble shootin', let me know...

i don't mind answering questions...

[jcniest5]

Hey Shim, are you then the webmaster of BE? I would also assume that you are also the owner? That's cool if you are. Anyway, my mod finally works as expected. The fluctuation is now between 1.65 - 1.70. Everyone once awhile, it goes down to 1.63, but it then quickly goes back to 1.66 and stays there about 99% (if not 99.999%) of the time. Thanks to you, I was also able to mod successfully my Antec True550. I'm now above the spec of all the (really low) voltage I mentioned earlier (not sure if it was this thread or another one.) :beer:

good to hear!

the antec mod was probably in a nother thread.. i learned how to do mine over at xtreme...

btw, i'm not the webmaster nor do i know who is :)

but i wouldn't mind being moderator for this thread :)

how about making my post a sticky :)

hahaha...

[RotorHead]

jcniest5,

You can find out who does what here at BE from this Linky (http://www.bleedinedge.com/forum/be_pagegen.php?id=about_be) :)

shimmishim,

Jim and I actually moderate this particular forum. If there is anything you wish to do with this thread, feel free to PM either of us and we will try to accommodate your needs.

As Mikki has said on several occasions, the BleedinEdge is all about you guys, and we are happy to help in any way we can. :thumb:

PS….You’ve been Sticky’d :D :D

[jcniest5]

Alright, now I know who you guys are, I'm coming ta get ya!!! Nah, just kidding. Don't take seriously. Anyway, I hope more people will see this site and come to use it just as I did. I don't remember how I stumbled to this site. But it's all good because it really helps me. Of course, I did kill something, but also managed to learn something in doing so. That's all for the good! LOL...

you can use a fixed resistor between the ranges of 27-33K..28K will give you the correct vcore but with wider range of fluctuation, 33K will give you a slight increase in vcore but less fluctuation.... 30K is the one that falls in-between..

**use a soldering iron (30W or below)with small/sharp and clean tip..you can only use 40W or above if you have a good experience with soldering..:)

Looks great Shim . :thumbs:

thanks! :)

[Ice]

Lookin' good, shimmishim! I can't wait until I get my board back. :D

[jcniest5]

Ice, have you got your mobo back yet? How is it since modded? I modded mine about a month ago. It tends to work at times while not at other times. Sometimes I check on MBM5 and the fluctuation would still be the same way as before the mod. Other times, it tends to not fluctuate as much. So, I'm pretty getting over this mod thing now as I am not sure it works or not anymore. As I posted earlier, I tested a few resistors and found the 12K and 18K to work the best. I ended using the 18K. But who knows now, I could never tell as I said earlier above. :scratch:

regarding your vdimm mod.. it looks like you soldered on pin # 4 & 7 instead of pin # 4 & 6..maybe something's wrong with my eyes..:)

[shimmishim]

hehehe....

it's on #4 and #6... it's just the weird angle...

Well the mods were working fine, which I confirmed by using MBM5 to test the vdroop mod, and a multimeter to test the vdimm mod. However, there was an issue with the board where my memory modules became really hot to the point that it would error in Memtest86+ even at it's rated speed and timings. Also, the motherboard stopped making the beep sound after the POST, like it normally should. Neither me nor shimmishim could figure out what was causing these anomalies after much troubleshooting. I guess modding your board is a risk you must take, as nothing is guaranteed.

[shimmishim]

argh... i'm so sad your board isn't happy anymore :(

[Ice]

Don't stress, shimmishim. It's not the end of the world. :D I wish it could have lived happily ever after. You've been exceptionally helpful in trying to solve those problems. I just got a new P4C800-E Deluxe to replace this one. I'll probably keep it around, just in case. You never know what might happen. :)

[shimmishim]

finished another mod for qsw something something something lol...

i have pictures i will upload again but they look like the one for ice hehehe...

tell me how the board does sir!

Shim - which board (Asus or Abit) and which mod are these (VTT vdroop)? Looks very clean - great job.

[shimmishim]

it's not a vtt vdroop it's a vcore vdroop mod...

prevents the voltage from dropping like mad under load...

and it's for the asus p4c/p800 series boards

[qsw911]

Hi Guys, those were pix of my P4C800-E and I just installed the board. Everything works fine. Shimmishim did a great job. I am in awe :bow: .

OK b4 mod I was doing 250fsb with the 2.8C @1.600v in bios (fluctuates from 1.536-1.68 according to Asus Probe).

After mod: 2 instances of Prime stable for 2+ hours at 262fsb. Vcore when set at 1.65 in bios, idles at 1.664v and dips to 1.632v under load. This is with a SLK900U with a 92mm Tornado fan. I will hook up the waterblocks this weekend and post my final results.

I just briefly tested the Vmem mod and so far so good. I memtest-ed a pair of BH5 512mb sticks for abt 1 hr at 3.2v @ 235fsb, 1:1, 2-2-2-5. zero errors :)

Will update later, the fan is driving me nuts.

Do you do a VTT mod for the Abit IC7-Max3?

[shimmishim]

shimmishim

Do you do a VTT mod for the Abit IC7-Max3?

it's doable...

i've done it before to my board but i was unsuccessful because i didn't have a sharp enough object to cut my trace... but now i have an xacto knife and it should be no problem....

i did the vtt mod to my abit nf7-s and it worked perfectly fine.

[BigStan]

Which version of the VTT mod are you doing?

Hey Shimm? Could you post a pic of the AGP mod for the P4C800-E? Please? I want to try the mod and malves' site is down...he was the only one I knew that had a shot of it.

[shimmishim]

i've never tried the agp mod for the p4c800 so i don't know what it looks like...

why don't you try xtremesystems.org and searching the modding section and see if you can find it

[shimmishim]

hi

i found out the vagp mod

pin #6 and #11 on this chip...

[shimmishim]

http://www.johnshim.com/mods/P4C800_Droop_1.jpg

[shimmishim]

and as long as this thread never dies, this will be a good way for me to remember how to do this mod cuz i couldn't remember hehehe ... thank God for Hell-fire

[Snafu]

Very nice. You must have some amazing eyesight.

P.S. Very nice macro lens - love the shots.

[kraggy]

Very sweet mods! They are so clean it looks like they were done in a factory! Hey shimm, do you know what to set the Ohms for on Malves' AGP mod for default voltage? I sent him PM thru extreme but no reply.......

[shimmishim]

for default i assume that you would have to leave the VR to max resistance and then lower it to get higher voltages...

i dunno what ohm vr you need but you have to set it to max :) hope that helps

[kraggy]

Yep...it helps. The one in Malves' pic is a 200k trimmer. So I will set it to 200k Ohms and then check it with a multi-meter.

[macg]

is the droop mod doable for the p4p800-e deluxe??

[shimmishim]

i need to ask to see if the layout is the same as the p4p800 non-e

if it is, then yes, it's doable... and even if the layout is different, if it's available online, i am able to do it.

[macg]

my p4p800-e deluxe is messed up.. i set vcore to 1.6 and it shows 1.552 idle, fluctuates between 1.522-1.488 when priming!!! prime is unstable. dang......

hey guys... all modding services suspended until further notice...

seems as though school is gonna be killing me this semester...

if you guys still have modding questions, go ahead and post here... i will do my best to answer questions and PM's...

as for those that have requested modding services, if your mobo's don't get here soon, then i am going to have to deny you guys service...

there were two people that wanted p4c800's modded... hope they were sent because i won't have any time to work on them after today...

also if you guys need mods done, you can contact Hell-Fire over at xtremesystems.org.. he does fine work and has a lot more knowledge than i do as he is a computer or electrical engineering major...

i will probably start mods up again in december but don't worry, i will stay on top of all the popular vmods that i can :)

good luck to you guys! :)

I’d love to do this mod does anyone have more info on it….the how to if you will? As well as the best location to get the parts for this mod? And any other words of wisdom.

which mod are you referring to?

[tbyte]

I'd like to do the Vdroop and the Vdimm both. I have the P4P800 Dlx board. I know I've seen pics but for some reason I can't seem to find them now.

[shimmishim]

vdimm mod
http://www.johnshim.com/mods/boshuter/IMG_1130s.jpg

vdroop is slightly different from the p4c800

the vdimm is the same for both boards...

[tbyte]

Cool thanks. What other parts do I need for this? And where is the best place to get them.

[shimmishim]

you need to pick up some potentiometers which you can do form your local radio shack... soldering iron... for wires, i use an old IDE cable... they work VERY well.

i don't remember what resistance... it's been a while since i've done a vmod....

i believe it's 50K... the higher the resistance, the finer you can tune the voltage.

[harleybro]

Are you doing the modding again? If so have you done a MSI Neo2 Plat.? Also if you are modding again I would like to pass this link to some people. Your work looks great!!! :bow:

[shimmishim]

hi, i can do the mod as long as i can find a diagram of the chip that needs to be modded to.

luckily, i also just picked up a 939 processor so i can test it as well :)

so yeah, modding services have started up again! just need to find my soldering iron and pots :)

[shimmishim]

hey shimmishim, i'm curios if you know how to mod a 9700pro cause i can't push it past 350 core/ 336 mem for the life of me, even when i have them water cooled.

[shimmishim]

sorry for the late reply... yes i can do the 9700pro mod... :)

i can also do:

EPoX 9NDA3J/+ vdimm mod
EPoX 9NDA3J/+ vcore mod

going to read up on the X800XL mods :)

Hi, do you have a vdimm mod to the Abit AI7? i really need one couz my booster wont fit when i use slots 2 and 4. How much voltage do you think i can have with the vdimm mod? Do I have to make a psu mod too?

[shimmishim]

http://www.xtremesystems.org/forums/showthread.php?s=&threadid=23491

and yes you will need to do the 3.3 volt rail mod for your psu

i forgot who it was but someone did this a very nice write up on this mod on bleedinedge

[abo]

ok thank, where can I find that mod that someone did here on bleedinedge? couz I want like a guide step by step how I do this with pictures.

[Shah1904]

Hi shimmishim ! Need some help from you. Im planning to do the droop mod on my mobo. Its a MSI PT880 and uses a ST microelectronics L6710 voltage regulator. Can you help me determine the right pins and value for the pot.

Thanks in advance :D

do you happen to have link or diagram of this chip?

if not it's okay... i'll ask around

[shimmishim]

i think i've found it but i need to verify what chip to mod to first or make sure it is the L6710 chip.

[shimmishim]

ISL6556B is the chip not the L6710

so... 20K VR on pins 12 and 14

middle leg to ground

that should do it

[Shah1904]

No..Im sure its a L6710. You can get the datasheet from here.. hope this helps

[harty]

Hiya shimmishim. I know that someone has asked you about the P4P800-E Deluxe ages ago, but I'll ask again. Can you or have you done the vdroop mod successfully for the E Deluxe board? I have one and am interested in your expert service.

[shimmishim]

p4p800? hmm...

i've done the p4c800 many times before...

i'd have to find the mods online somewhere to do it for the p4p800-e.

[harty]

You had a link to the mod on page 7, post #104. Anyway, here it is again: http://www.xtremesystems.org/forums/showthread.php?postid=502880#post502880. Let me know if you can do it. Thanks for the quick response, shimmishim.

Curious side question: I recently purchased a P5B Deluxe for a C2D (but haven't set up the new sys tho). I see that you have the P5B Deluxe board as well. Does it exhibit droop problems to warrant a mod, or did you mod yours just because you could?

[Dark_Star]

hey i am new to this type of modding i usally just do cases lights and water coolers but wat r these ones and wat do they do?

[shimmishim]

these are voltage mods.

they allow you to get more voltage than what the bios allows or they fix the voltage droop that a lot of boards exhibit.

No, I don't nailpolish them but that is actually quite a good idea.

I have to say that this has to be one of the cleanest mods I've done.

Usually for myself, I do quick and dirty... these were clean, used the least amount of solder ever!
