OLD SCHOOL... P4C800 vCore question.

post #1 of 5
Thread Starter 
New to the forum so if this is in the wrong place, i apologize. I've searched the web high and low for the answer to this but can't seem to find the exact same question asked before.

I've read that 1.5 -1.55v is about the tops for air cooling on the P4C800 board, but with the vdroop and the inconsistancy between the BIOS and what Windows reads I'm curious to know if the 1.5v rule of thumb is for the settings in the BIOS, what windows reads at idle, or what windows reads under load??

I'm currently stuck at about 3.83 on my 3.4 Prescott and upping the vCore isn't helping me pass Prime95. I started out at 1.45 in the BIOS and upped it all the way to 1.525. Windows is reading 1.54v at idle and drops down to 1.44v under load. My max temps at 1.525v are at 68c. So, can i up this voltage safely?

Also, I'm aware of the vdroop mods, but don't think i'm wanting to put that much effort into an old 478 set up.

Thanks in advance.

Well, even if I perform the vdroop mod I would still liketo know what people are referring to as the limit these Prescott chips can take. Is it what you set it to in the BIOS? What you read in windows at idle? Or what windows reads under load?

Are there no old school overclockers out there that know anything about this board?

i had one, the rating on voltage is what you set in BIOS. These chips can take a lot of voltage i wouldn't be too afraid. They just run really hot a lot hotter than northwood.
