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

Cheers, Slipstreem. :cool:

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 :)

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. :)

fsb/Multiplier overclock question

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
