Maybe then, in many cases Intel binned them at a lower VID for stock, because they simply ran too hot at a higher VID? wink.gif

Doubt it, when I say hotter, I'm talking a couple of degrees, nothing huge

At 460MHz FSB with CPU and RAM underclocked. Just had to overvolt the FSB Termination Voltage from 1.20 to 1.24, running large FFTs now. If it goes an hour I'll go to 465, then 470, then 475. I'll try for 6hr stability at 475MHz.

An hour won't cut it. You need to go at least 6 hours... And believe me, when going 465, 470 and so on, Large FFT's will not run for long without error.

475FSB will require 1.6v + on the VTT. I've tested it in my P5Q Pro Turbo, and even then Large FFT's will crap out sooner or later..

Don't be such a pessimist. Experimenting is what OCing is all about. Maybe it's just your board, or just the Pro Turbo model, or maybe your chip. And even if it's been confirmed on dozens of these boards, it's better to find out the limits for myself, rather than half you shouting at me that it won't work.

Me and my mentor in these P5Q boards, the King, KingT have spent months testing these things So I know what I'm talking about

And the P5Q Pro and P5Q Pro Turbo are almost identical boards

At 465MHz and trying each GTL setting to see the impact on Prime95 stability.
post #58 of 77
Thread Starter 
Been stable for about 30 minutes with these settings:

Clock: 2826MHz
Multi: x6
FSB: 471MHz
DRAM: 942MHz
Vcc: 1.21875V
GTL: x.61
PLL: 1.64V
VTT: 1.34V
DRAMV: 1.96V
NB: 1.24V
SB: 1.20V
PCIe: 1.50V

Going to let it run for another six hours and see how it does.




EDIT: For reference, 3700MHz settings:

Clock: 3697.5MHz
Multi: x8.5
DAM: 1045MHz
Vcc: 1.21875V
GTL: Auto
PLL: 1.64V
VTT: 1.20V
DRAMV: 1.96V
NB: 1.20V
SB: 1.20V
PCIe: 1.50V

Your PLL should not need being that high.. Most common for 45nm overclocking is 1.52 to 1.56v range.. Be careful with that. Can damage your Clock generator..

For S775, that's platinum.
