P4P800 Del - vcore fluke or fix?

[Crabash]

I just built a new sys with a P4P800 D and 2.6c running on a Prommie Mach 2, but I got the mobo before the cpu and used my old 2.5 (400) for a week or so 1st. I decided to use some conductive paint to join the pin's on the cpu to give 1.85v as I had 1.6 max as standard, when I booted it gave me no control and was locked at 1.85v, I then flashed the bios to 1010 which then gave me options from 1.85 to 1.95 volts in the normal 0.025 step's.
I then got my 2.6c and once installed (WITHOUT the cpu pin's joined) I noticed I now had vcore option's from 1.525 to 1.95 in the normal steps again.
Or am I way off and the bios revision gave you these extra setting's anyway?

You don't get anything below the VID cpu setting.

No it gave me min of 1.85v with the pin's joined and min of 1.525 with the new cpu. Max 1.95v in both cases.

The bios revision is responsible for the Vcore range.

Sorry to hijack the thread but does the 865PE based Asus have PAT enabled like the 875 ?

I know Intel said it didn't but then Asus got tested and it was very fast and Asus had managed to enable it, then Intel kicked up a fuss and so Asus changed the name of it to something else ;)

Is it still enabled and so as fast as a 875 board, or should I spend the extra and get a replacment 875 for my blown up current one ?

Asus' 865 m/b has PAT (=MAM), but it is partially enabled at default speed (with 800 mhz cpu). Bigtoe came up with a procedure to fool the board and put it into a full PAT (=MAM) mode but that eliminates using the lower memory ratios. You are stuck with DDR400 or 1:1 setting. So, the best cpu is a 2.8, 3.0 or 3.2 if you went the mod bios scenario. I 'm using it with a 3.0. It pumps out better bandwidth by about 150 points with BT's mod.

Your best bet if you live in the USA is buy a refurb Asus P4C800 from Newegg for $99 USD. You have a 15 day warranty to return it if it is not working correctly.

I would say stick with the P4C800 just in case this newest 3.2 Xeon style cpu with 2.5 mb of cache will only work on an 875 chipset board.

Thanks Ace, that post covered all points. I will stick to 875 as it is more but not more compared to the new Extreme Edition P4 that I am thinking about ( though it will be expensive).

Nice of Intel to name their latest processor after this site :D

the updated bios give the addional voltages but be careful I just had to use the reset jumper to get my machine back after adjusting to 1.825Vcore

I found that my 3G@3.5 would stop working at 1.725 or above. it just wouldn't boot but it would post so getting back into the bios was easy...

......why would you go that high of a vcore? Ever hear of SND?.....

[notdave]

cause 1.8 didnt get me more FSB, stupid i know

[Ace-a-Rue]

No, not stupid! You are an explorer, a man who needs to discover on his own. I think you are pretty brave in my book to even post it up!:up:

....hehehehe- that is the best answer you could have said. Now the 1.825v makes sense to me..............
