MAX VOLTAGE FOR PD805

[FrostedNipple]

hi, im a proud owner of a pentium d 805 2.66GHz lol
curently i have it clocked at 3.6GHz =D @ 1.4750V
is tht way too high or not, anly less volts and it is not stable, i am running SuperPi 32M right now, it seems to be going ok, but how high can i make the voltage to go, i am planning on clocking further =D

BTW the question is,,, What is the maximum voltge i can put through a Pentium D 805 CPU ? =D


---EDIT---
Super Pi 32M complete, didnt crash so i assume all is good

Mine will run 3.9 ghz with 1.40V
That's 1.40V under load not in Bios though.
It depends on your mobo how much droop you get how high you have to set Vcore in Bios.
If vcore drops below 1.40V under load crash happens.
Also if temp goes above 60degreees crash happens.

It seems common to run them up to 1.60V if you can keep the temp down.
Not at all easy on one of these, top grade water at the very least.

Got mine the other day. Got her at 3.7 with stock volts. Will tweak thoroughly at some point, though I don't really want to increase the voltage at all, as these things suck a lot of power.

Superpi isn't very stressing, use this bad boy:

blimey, i have to run mine at 1.5v to get 3.6gigz, i got it to 3.8gigz and that was at 1.6v, unfortunaly, my case is old so old that when they made it they didnt realise what fans where, (very bad cooling lol, so at 65 it crashes, hopefully i get new case soon then i should have better temps) i spose only time will tell =D. are u shore u wernt lying, last person,

You need to be sure the voltages you are talking about are real under load voltages and not BIOS settings.
Watch the Vcore in CPU-Z when you load the CPU up and see how it droops.
The voltages I'm talking about are the lower ones when it's under load.
Often they have to be set higher in Bios or a Board mod done to achieve these voltages.
This is especially true with the dual core CPU we are talking about, they draw so much power it's not funny.

it's true, they draw so much power that the fans on my psu spin up big time under load and eventually my psu makes my computer crash...

I can get 4ghz stable in bios at 1.525v, but cpuz is showing 1.288v to 1.304v.. so thats a fair bit of droop.. but stable none the less, its been in windows at 4.3, but only just 4.2 was the best cpuz shot i could get

It's on a P5N32-SLi SE deluxe btw... (shh, board too good for cpu i know.. but it was FREE... awaiting C2D.. hehe)

EDIT: oh yeah, voltages, i had it at 1.65v in the bios at one point, seemed fine, primed ok, but was showing 1.52v in cpu-z..

viper, where you using air, because if you were what were your temps, please every post your temperatures at idle , load (or crash which ever come first lol )
