It seems springdale and canterwood are one and the same

[Tony]

Intel have protected the chipset from register hacking...why?
The new asus springdale is faster than its canterwood brother..why?

Im trying to get info on getting past the inbuilt protection on the chip, once i can see the registers we may see a whole lot of secrets uncovered...

Your thoughts..

[RotorHead]

bigtoe that is vary interesting :scratch:

It’s not to far fetched to believe Intel would produce both chipsets on the same die, then cripple part of it and call it by another name. That may account for the protected registers.

This would definitely reduce production costs and possibly increase the yields….. Of coarse this is all speculation.

Waddaya think

It's very like intel to do this. Celeron, for instance, is purposely crippled hardware.

I'd like to learn more about how they've protected it from register hacking.

[Tony]

I think we need to go balls out to find out how to hack the registers and turn PAT on for springdale.going off the memory benchmarks im seeing for springdale turning PAT on would kill canterwood all together...:)

[Mikki]

I agree...no sense in letting Intel stop us now...;) hack em!! :p

[Tony]

Prom has ordered the Asus...im sure a monster review will follow:)

I should have a fresh epox tomorrow as im off to OCUK to get it swapped while i wait..its also prommie friendly as reset holds the board from booting..so 300fsb may be on the cards with this one.;)

[RotorHead]

Did you just say 300fsb?....whatchootalkinbout willis:eek2:

[Tony]

I had 280fsb with the IC7 with 275 the max stable air cooled.This is with a 2.6C.The IC7 is not prommie compatible as reset does NOT hold the board from booting..this is why i opted for the epox...

[RotorHead]

Ok, I’m lost now

Your going to have to back brief me a little,

prommie :?:

reset does not hold the board from booting :?:

Prommie is a Prometeia phase change cooling device.It chills the cpu down to -33c before releasing the reset on the motherboard so the rig will boot.Taking the cpu down to -33c can release an extra 200mhz or more on a max air overclock usually at a lower voltage also.

http://www.chip-con.com/index.php?pageid=14 for the "Prommie"

The IC7 does not hold reset so even if you hold the button in the board carries on booting..this creates a problem with the prommie as the chip will not have chilled down before boot.

[ThugsRook]

Oooooo this is interesting :smash:

can wait to see how this works out :yummy:

[RotorHead]

OK, I got it now, it's a timing thing.

got to cool it down first before it powers up at a hi FSB or it will thermaly overload before it gets a chance to even post.

See, ya learn somthing new every day....hehe :D

BT,

keep me updated on the EPox, its cheaper than my existing MSI board, am planning to get one Epox too. But can you volt mod the epox?

[CSHawkeye]

man i cant wait to get some ram that will run at 240 fsb so i can run my memory at 1:1.

Since Intel is reported use speed-binning for these chipsets (i.e. i875P MCHs that can't do PAT well enough become i865PE MCHs) I think it may be difficult to enable PAT (I'm not sure how big a slice the rejected i875P MCHs make of the total i865PE batch though).

Also, it's hard to tell how Intel would disable PAT. One way would be using fuse blowing or a technique similar to that (small on-chip PROM perhaps). I would think that they try to implement it in a permanent enough manner for them to be satisfied it will indeed stay disabled.

Since I don't have a Canterwood board I don't think I can help much, though. Disassembling a BIOS may give some indications but first of all I don't know how to do that, and second of all, my assembler knowledge isn't the best (I've played with PIC and Motorola 68008 assembler only :)).

BigToe,

Tanghiro reports in the AbxZone thread titled

"Asus P4P800 (865) beats ALL 875 & 865 Boards"

that he has run the P4P800 at 348 fsb :eek: using a 1.7 mobile chip I believe. His screen capture shows the 348 fsb displayed by the SetFSB program.

Do you suppose he was booting to 348 or using SetFSB?

Could you have used SetFSB with the IC7 or is there a problem with using that software for high FSB?
