i dont have a stock cooler
i have a 92mm 6 heat pipe cooler
see links in first post
Never you said you did? And I read the entire thread.
i OCed for a little bit
getting it to 3Ghz was easy
but is not stable
i havent touched my voltages yet
and the max temp was around 60*C
i ran P95 for not even a full test and then tried to start FF
then it rebooted on me
interesting fact is that i could get 6.7GHz if i left it at that freq
but im not that dumb
i want this pc to last for a while
and still perform for me
My advice would be to go back to defaults (load fail safe defaults). It's easier to start with a clean slate.
1. We want to eliminate all variables, so set the RAM:FSB ratio to 1:1. Sometimes you won't have a ratio option in the BIOS, just a DRAM frequency option. At default, your FSB is 266 (266x10=2666MHz=2.66GHz), so RAM frequency should be DDR 533. (Don't worry, we'll deal with this later)
2. Set all voltages manually. If left on auto, the motherboard will try to determine voltages for the set frequency itself, which it's not very good at (probably the cause of your instability).
Set voltages to these values:
FSB voltage/VTT voltage (goes by either of these names): 1.2V-1.3V for the 65nms. Preferably 1.2V if this option is available.
CPU PLL: 1.5V
NB voltage: Lowest value available, this is the default. We may have to increase this later but it should be fine.
3. Disable CPU spread spectrum and PCIE spread spectrum.
4. Now, simply change your FSB frequency from 266 to 300MHz. Make sure the multiplier is set to 10x. 300MHz x 10 = 3000MHz = 3GHz.
5. If this really is a G0, it should boot into Windows with zero probs, Nvidia chipsets really do suck if it doesn't.
If it doesn't, or if Prime 95 reports an error or reboots, the first place to look is the Vcore. Increase it in small jumps up to around 1.35V. If it's still crashing at this Vcore, we know that's not the problem. Raise the NB voltage up one notch next. This is likely to be the problem if the Vcore isn't. If that doesn't work, report back with shots of CPU-Z (to see in Windows voltages)
