| Hi, I need a little help on trying to get more performance and stability out of my E4400 and P5KC. Somebody told me that if i reduce the multiplier to 6 and increase fsb to 400 with the memory running a 1.1 ratio at 800 my pc should be faster than at 10x300. I tried this but after running orthos for an hour with no problems i rebooted the pc, but i got no post so i switched it off and on only to be given the message 'overclock failed, please press F1 to run setup'. Could anyone advise me on the fsb/multiplier setup for my pc and what voltages should i be running in either situation. Ive also been getting windows xp stuck at splash screen when its loading with any overclock. my bios is version 08.00.12

You need to make sure that it's totally stable with the overclock in Windows first ideally, and I'd stick to the standard multiplier if I were you. The FSB of 400MHz is obviously causing a problem somewhere even with a multi of x6, so I'd avoid going that high personally. Maybe the mobo chipset is cooking and needs better cooling. I don't honestly think that a high FSB is going to help you much anyway.
The CPU is designed to run with a higher multiplier and the relatively slow FSB can still provide all the bandwidth an E4xxx needs to keep it 100% busy. The 2MB L2 cache is likely to become a problem long before FSB bandwidth limitations take effect. Not that the 2MB of cache is a serious problem either.
Use the proper CPU multiplier and try tightening your memory timings if you can. Running the RAM slower but on tighter timings will often pick up a measurable performance boost and tends to make a C2D very 'snappy' for its clock speed. You may need to raise Vcore a little above stock (to around 1.4 to 1.5Volts?) to get a really good overclock though. 
Cheers, Slipstreem.

| Hi, I kept the mulitplier at 10 like you suggested slippy and i raised the fsb to 266 with the voltage at 1.4. I then set the memory at 667 with timings of 3 3 3 8 , i dropped these down from 4 4 4 12, hope these look right. Ran orthos for 30 mins, no problems and both cores went to 60c with the cpu showing 38, are these ok? PC rebooted a few times and everything seems stable. Thanks slipstream

No worries, Sidders. Those temps sound fine. Glad to be of help.
