EPoX EP-9NPA3ULTRA & overclock problems

[sonoma1993]

I have the EPoX EP-9NPA3ULTRA Socket 939 NVIDIA nForce4 Ultra, im trying to overclock my cpu but it not working right. I set the cpu fsb to 234mhz and i put my memory to 166mhz, with the 34mhz overclock it would bring my memory back up to 200mhz. But when i goto restart my computer, it just boots up as 200mhz x10 and the memory will be set at 166mhz. any suggestions?

Have you tried lowering the HTT multiplier to 4x? I forget which exact menu it's under, but it's the second or third one on the left side (Advanced chipset options, or something similar). Your HTT speed is the product of the FSB and the HTT multiplier and should be as close to 1000MHz as possible. There is no significant performance hit if the HTT is much lower than 1000MHz, but you'll get stability issues if it's much higher.
