Help overclocking Intel P4 2.6Ghz Northwood (478) Tags: Overclocking Intel Last response: January 23, 2009 7:06 PM in Overclocking Share GSD December 14, 2008 11:47:48 PM Hi all. I've decided to try and OC my old rig (Intel P4 2.6Ghz Northwood S478/ Asus P4P800SE / 1GB (2X512MB) Corsair XMS3200XL (2-2-2-5). I am very new to overclocking and need some help. I have the XP-90 CPU cooler which is keeping temps ~ 30C idle and around 36-39C full load using Prime95. The thing I am confused about is the RAM frequency. Here is what I've done so far; Gone into BIOS and slowly increase FSB to 240MHz (currently running stable @ 3.1GHz). I opened CPU-Z to find the memory running at 160MHz - why is this? Shouldn't it be running at 240MHz? Will my RAM go to 240MHz OK? Screenshots; Any help would be appreciated.

Will it help if I increase the CPU voltage? What is a safe voltage to use with this CPU?

What is a safe voltage to use with this CPU? The reason for failure could be a RAM not a CPU. You didnt attach an SPD screen of CPUz which will show Your memory timing. Maybe at 160MHz is CL2 too tight for them. Can't find your answer ? Ask ! Publish Related resources Pentium 4 2.6GHz Northwood Socket 478 Overclockability?
