*Another P4P800 WOW*

[Skully]

I'm setting it up as I type this. So far I like the bios, and the strong voltage rails. The AGP slot is far enough away from the first PCI slot, that you don't lose a PCI slot. Will report more later! :)

[LastRide]

My P4P800 is on the way.:)

[Sweeper]

So Skullster...

Give us an update??? How's it working for you??? Don't keep us in suspense... :D :D

Sweeper :wave: Running great this P4P800 Deluxe. My 2.53 oc up to 165fsb stable, running well over 3000. I ordered a 2.6c today, it will be interesting to see how it will oc. This is one great mobo.

[Thor]

Yeah, this board is pretty solid. Power rails are rock solid, and the overvolt is only about .04 more on idle. I can certainly live with that vs. my P4G8X!

Looking forward to seeing your 2.6 setup, sigh, now I'm really getting tempted. :-)

[Thor]

Well, just got my hands on a 2.4C and a 2.6C both L311As, see what they will do on my P4P800.

[LastRide]

Please let us know how it goes.I should have my P4P800 and 2.4C L0310 tomorrow:)

...and im right behind you ~ on Wednesday.

:wave:

[Skully]

I just got my 2.6c today. Installed on the P4P800 Del. I'm now running fsb260/1040, 2.6c running @ 3.38. Just started playing, hope to get more mhz as I learn this setup. My memory is Mushkin PC3200 & Corsair PC3200 ddr400. This is on a H2o rig. :cool:

[Tony]

I found 275fsb real sweet on the p4p800 and pushed it to 281fsb for the odd 3drun..all air cooled!!!

Lots of fun still to be has Skully! You have only just started;)

[LastRide]

bigtoe,whats the max the P4P800 will do stable,280FSB?.I have the 2.4C and wondering how much I'll be able to push it.I don't have the 2.4C yet,tomorrow.

[pastorjay]

I'll have my P4P800 in a couple days! Along with my raptors!

I think 300fsb should be easy for you if the cpu can do it.

[Skully]

I'm running 1008 bios, my 12v rail was 12.99 now its 12.38. I was running 260fsb stable, now I'm at 270fsb it seems stable so far. Sandra buffered 5967/5943 unbuffered 2755/2817. My 2.6c is @ 3515mhz! Not bad hey? I haven't tried any higher yet! Memory timinge 2.5, 2, 3, 6 @ 5:4/320. This is with DDR400 memory.

[Skully]

My memory scores in Sandra really drop off below 270fsb. I found that I can run stable @ 272fsb according to Docmem. My Sandra scores @ 272fsb are 5920/5977 buffered and 2772/2841 unbuffered. My 2.6c is running @ 3537mhz, 5:4/320. I only count what I can run stable at, I can get into windows at 290fsb but not stable. My memory is Mushkin enhanced pc3200 and Corsair pc3200. I need some stronger stuff/memory, I feel theres more head room with this 2.6c. This 2.6c is one sweet oc'er and the same could be said for the P4P800 Del.

[ErikaeanLogic]

so, would you say that the 1008 bios gave you more headroom? did you have a ceiling of fsb before which the newer bios lets you bypass now? that would be good news!:rock:

After cooling down the North bridge from 95f to 82f. I'm surfing BE @ 280fsb @ 5:4/320. My 2.6c @ 3.64mhz, one sweet cpu. Yea, cool down that North chip and you'll for sure get higher oc's! Plus upgrade to the 1008.001 bios. :)

[Sweeper]

Hey Skully...

What are your memory settings??? Do you have it set by SPD or set manual.... do you have memory exceleration on or auto?

I got a couple of BSOD and reboots today... I turned memory excelleration off and so far no BSOD.

Sweeper

[Skully]

Memory manual, 2.5 2 3 6, memory exceleration on, turbo on! Running stable @ 277, can run 280mhz with higher Vcore. Vcore now @ 1.65v. :)

hey skully, how'd you cool your NB? I've got a small 40mm fan on the heatsink there which keeps it cool to the touch but I can't seem to get past 268fsb (5:4, 215 actual) no matter which RAM I try (XMS3200C2, TwinMOS CH-5, Buffalo PC3700) or how slack the timings are:confused:

The P4P800 looks sweet. Which of these three boards do you
think has the highest stable fsb: P4P800 non-deluxe, IS7,
IC7 non-G ? All are about the same price here.

[pitzuchim]

I've got the P4P800-D with a 2.8C and 2x512MB of Corsair 3200LL ram. I can't seem to OC much... even at 240 FSB with 5:4 ratio, Prime95 crashed immediately.

My settings:

What brand memory are you using? Your issue sounds like one I had while trying to use memory with Winbond CH-5 chips on it

[pitzuchim]

My memory is Corsair XMS 3200LL twin pack (2x512 MB)

I've moved my replies over to your thread;).

[Flamer]

pitzuchim,


Is it possoble hat your cpu is holding you back, What kind off cooling do you have? And maybe try to raise v-core to achieve stability. I have had 2x256 corsair xms cas2 pc 3200 running at ddr 418 2,3,3,6 at 2.85 volts btw.

[pitzuchim]

I'm using stock cooling. I don't want to do any extreme overclocking, or to use voltages that will lower my CPU life. I just want a decent, stable OC. samcolt, what's your vcore at?

[Flamer]

Well i am not running a 2.8c :(but at the moment i am running a 3.06 at 148 fsb at default v-core wich is 1.55v, but when i use the prometeia i try not to go over like 1.7 or so. but many people feel you can run at 1.65 volts on air and not hurt your chip. But you may wanna look at getting a new heatsink because the stock one sucks big time, i like the swiftteck mcx4000 BTW. To let you know i have seen the stock intel heatsink even the good with the copperbase not provide the cooling needed to run my chip at 150 fsb, i have seen bluescreens and crashes from heat.

[pitzuchim]

I just got everything running stable at 230 FSB with a 5:4 ratio. I don't think I'll go any higher; 3220 mhz is plenty and my RAM timings are great at 2/2/3/6. Also, I don't want to increase the voltages. Right now they are at: vcore=auto, dimm=2.75v, AGP=1.5v. Since I am using stock cooling, overclocking more would probably not be such a good idea anyway. The system is running great now... thanks for all the input guys!

[XJ.]

Man, you guys are tempting me towards the *darkside*. Luckily for me, I already blew my BDay money, so I'm safe for now :p

[Chuck232]

Hehe.. XJ, seems quite a few AMD users are switching over just to experience the o/cing potential on these C chips...:D

[pitzuchim]

Quick question... what's the stock voltage on the 2.8 P4C? I set my voltage to 1.55v, since I don't like not knowing what it is (when it was on auto). Is this too high? Right now I've been running two instances of Prime95 for over 12 hours with no errors.

[Chuck232]

Stock voltages are 1.525V I'm pretty sure. 1.55V is not high at all, but for these P4Cs they're doing ~80-90% of thier o/c at stock voltages or close to stock voltages. Upping the voltages much doesn't seem to help overclocking on these chips.

[pitzuchim]

Thanks... I'll change the voltage back to 1.525 and see if it's still stable.

[XJ.]

That is what is so cool about those chips - instead of running my AMD at 1.95v :rolleyes:

[pitzuchim]

I finally understand why I couldn't go above 230 FSB... my problem wasnt RAM, it was cooling. the RAM should easily hit 250 FSB even at 5:4, right? (Corsair XMS 3200LL RAM). Now I wanna see how fast this RAM can run. Hopefully I can hit 230 FSB at 1:1... I might have to slow the timings down a bit, but since its low latency RAM, it should still run go decently fast.

[pitzuchim]

Man, now I'm starting to feel REALLY tempted to get a Zalman 7000 Cu heatsink/fan and some arctic silver ceramique, and to exchange my Corsair 3200LL RAM for something that goes faster. If I were to do this, what RAM would you guys get?

*edit* damn, apparently that zlamna HSF doesnt fit the P4P800. Back to the drawing board.

[ErikaeanLogic]

if you're running at stock voltage, cooling ought not be an issue even with the Intel stock HS. You may want to confirm that the heatsink mounting bracket is fully flush with the motherboard; any space there would mean that you have space between the HS and the cpu.

Which slots are you using for the memory(1+3 or 2+4)? That makes a difference, you know;). 2+4 is the official THUGSROOK preference with the P4P800, and many of us have also witnessed this. Also, I have found that I get the most stable performance out of my XMS sticks when I bump the Vdimm up to 2.75V.

[pitzuchim]

Darn... I was using slots 1+3. I'm pretty sure the HSF is seated correctly, it seemed pretty idiot-proof :-) I'll move the RAM to slot 2+4, and hope that I can hit 230 FSB with 2.5/3/3/7. Maybe this will work with 2.85 volts... gah I just want to get home now so I can test this :-)

[Chuck232]

Instability can be caused by high temps and running stock cooler at 3.2GHz is no small feat.

I ordered a SLK-900U along with a 92mm ThermalTake fan, so I hope that'll do me for cooling.

[pitzuchim]

What are some of the good heatsink/fans, and how do I know if they will fit the P4P800-Deluxe? Also... since I am currently using the stock HSF, would I have to clean the processor before I use something like Arctic Silver?

[XJ.]

Check here (http://www.overclockers.com/articles373/) you'll need to scroll down a bit. Thermalright has some of the best HSF.

[XJ.]

Geez and 80cfm Delta - I'd go deaf! Thank God I have water cooling ;)

[pitzuchim]

Hmm... do you think it would be necessary to get a fan for my northbridge on the P4P800-Deluxe? If so, what fan should I get, and how do they mount?

[Skully]

I have a 120mm fan blowing on my NB. It makes a big difference. Before fan 95-96f after 82-84f! :)

[pitzuchim]

Are you deaf? Does someone constantly vaccuum the floor right next to you? Do you live next to a railroad track with an infinitely long train driving full speed on it? If you answered no to all of these... how can you stand the noise of such a massive, massive fan?

Hehehe ok so anyway... how do I know WHICH fan to get, and how do I mount it? Does not having a fan on the northbridge mean I can't reach as high an FSB?

[XJ.]

120mm fans are not necessarily noisy. Additionally, they produce a lower frequency hum, and are thus less annoying. I have a Panaflow 120mm that produces 70cfm at 30dbA - not bad at all :)

My setup may not be for everyone, as I run my case with the side panel off. This is because I run an outside the case water rig. Cooling the NB down will usually let you oc a little more with stability.

[pitzuchim]

Does cooling the NB generally make it so you can go higher with the FSB, or higher with the CPU speed? I know these two are linked, but maybe a cooled NB will let you go 250 FSB at 5:4 but not 250 FSB at 1:1, etc

Not a lot but some, if nothing else you gain stability.

When switching from 250mhz 5:4 to 1:1 NB may not be the limiting factor here. It's your mem. ;)

[Skully]

Also try keeping the memory cool. The same 120mm fan I have blowing on the NB also blows on the memory. My memory on the IC7 was getting quite warm to the touch. After applying the fan, much cooler to the touch. :)

[pitzuchim]

Yeah I know the problem is with the mem right now. That was a hypothetical example. Anyway... I think I'll just stick to casual overclocking. I don't want my system to be too loud, anyway.

[Croc]

So far I am happy with the P4P800. The 2.6C is running at 3.2 gigs now at 1.575 vcore 5:4. I installed a Zalman 7000ALCU tonight with Ceramique and the temps went down 4C so far at idle to 31C. I expect that to drop a tad after the Ceramique settles in.

The Northbridge ran hot so I pulled it off and found the hs paste Asus used was only about half on. Some repair there and back on after slicing the foam pad a tad to allow my temp probe ifurther in.
I also installed a fan from a Thermaltake Blue Orb. That is hooked up to my new Vantec Rheobus so I know it makes a difference and the temps dropped about another 4C.
Kinda matches the Zalman 92mm too. Not ideal but will do for now. Seems the Zalman helps get ait to the ram but I would like to get more air into that corner.

The OCZ3700Gold I have is holding me back at 1:1 at 233mhz and above. Memtest returned errors so it looks like an RMA will take care of that.

When that is resolved I will see how far the 2.6C will go.

[Chuck232]

I don't understand how everyone says their NB is so hot.. I can touch my NB and it's not even warm. I mean it feels colder than my body temps. Iono why that it....:confused:

[XJ.]

Chuck232, maybe the HS isn't on right :confused: That could explain the problems of overclocking you chip (if the NB HS doesn't have good contact with the NB chip, the HS would be cool, but the NB chip would be hotter than hell).

It might be worth taking a look...

[Chuck232]

Hehe.. That's what I thought, so I took the thing off and reapplied some thermal paste. But one thing I noticed. When I removed the HS from the NB, I saw this somewhat thick nastiness on the bottom. It wasn't really even touching the die except for the edges. So anyways, I reapplied the thermal paste, but it was fairly thing. Perhaps, it's still not really contacting properly. There's this foam ring on the bottom of the HS. Perhaps that's preventing good contact? I didn't remove it cause the die doesn't have a heatspreader on it so I was afraid I'd chip/crack the core if I removed it.

Any ideas?

[XJ.]

Well, check around, maybe at the xtremesystems forum (those guys will try anything) to see who has removed this "ring". Personlly, I'd probably try to get it off (with a razor blade, or maybe some acetone or desolve-it).

[Chuck232]

I will go check there!

Thanks! :D

[XJ.]

NP, GL!

[Croc]

I had a good look at the heatsink and the way it was installed with the mobo out of the box. The chip is raised up higher than the pcb and the foam strips aid in seating the heatsink flush to the chip and prevents touching the contact points on the pcb underneath. I just took a bit of the foam tape off to allow me to slide the tip of the temp probe right up to the chip underneath the heat sink. Temp now reads 34C.

Maybe just leaving small bits of the foam at the corners is enough to help it seat flush and help the chip breathe better.

I agree that a better sink with active fan cooling would be better. Monky has ordered a Thermaltake Tiger and, for now, I will stick with the Blue Orb fan.

[Chuck232]

Hm... so would you not suggest removing the foam ring all together?

[LastRide]

I took off the foam thing around the botton of the NB heatsink on my IC7.I used AS3 Ceramique paste (non conductive).You want to apply it thin.If it squishes out the sides its way too much.

[LastRide]

The core looks like a core on an AMD chip and CPU heatsinks fit a lot tighter than the NB heatsinks do.I took off the foam so the heat doesn't get caught inside and can escape out the sides if need be and air can get in there from like a side panel fan to help cool.

[Chuck232]

Alright I think I'll try that! :)

[Skully]
