Help me get my Q9650 stable at 4GHz

Last response: in Overclocking

It seems fine at 4GHz at 1.314v but when I run Intel Burn Test I get a error that saying either my CPU or Ram is unstable. Now I think it is the ram becuase I can boot at this voltage and when I boot at the max CPU voltage 1.3625v I get the same error in IBT. I don't really know what to look for to unlink my memory to DDR2 1066MHz. My memory Voltage is at 2.2v, FSB 1.28v, NB 1.26v

Please help.

Asus P5Q-Pro Intel P45 chipset. I can boot at 4.2GHz but get the same thing but this time with a BSOD. And CPU volts at 1.35v

Try dropping the multiplier to around 6x and pump up teh NB. This will allow u to find a good limit on the mobo and ur ram letting u play around with those voltages till its steady. Then start raising the CPU multiplier and play around with that once u have a good fsb limit

second thing. I don't think it is the CPU. at stock settings it still fails IBT on maximum performance put passes when I do 1/4. Where it dose not test the ram. I'm thinking of getting memtest86 and see if I have bad memory.
