I seem to have hit a barrier overclocking my E6600 in a P35-DS4 (Bios F7) at 400mhz fsb.

I’ve got the ram very relaxed speed (Crucial Ballistix 2GB 6400C4 BL2KIT12864AA804) so I’m sure its not that.

Even tried a lower multiplier but it still seems to need a lot of extra cpu voltage to go past 400mhz fsb and increasing the voltage a step at a time in the bios seems to only gain me a few extra minutes in prime before rounding errors.

At the moment I’m running 395mhz fsb for 3555mhz at 1.46 volt but can probably back the voltage off to 1.4 and its running about 65c max watercooled.

Can I expect any more out of this?

Also what does this board consider normal RAM voltage? In bios settings for voltage are normal / then +0.05v / and so on but I see these Ballistix require quite a lot of voltage compaired to others as spect by manufacture 2.2volt.

I just don’t get this. 399 MHz FSB 12 hours prime stable and 1 more MHz 400fsb and it fails in minutes. There must be more I can get out of this CPU because it went up to 399 on 1.4 volts.

I’ve been having a look in the bios and there some bits I’m not quite sure of to start playing with next.
One is FSB overvolt control. How safe is that to play with?
The other is MCH overvolt control. What’s that? Northbridge I take it! How much should I be giving that?

Is speed step worth disabling?

Any help appreciated.
 
Mobo's can be funny things! my Asus P5K-E Runs fine at 424 or 426 but not 425... just a matter to finding what it does and doesnt like
