@ nullifier, why is it rebooting three times when you save the settings?? You do realise that your ram is linked to your FSB and is running at 1066MHz don't you? did you increase the vdimm?? Loosen the timings??
Slight hijack:
There is no speedstep thing in mine either. It is just automatic. When I do something that uses alot of CPU power it automatically Goes to my OC setting. If it is idle it goes below stock down to 2.1Ghz.
Rubbish, it's there, I wish I had mine running, I'll dig out the manual.
It is speedstep, pure and simple.
EDIT: Just remembered that when you have Jumper free set to manual the speed step option disappears from the cpu configuration tab (iirc, working from memory again,
)
Look, there is vdrop, difference between bios and windows idle and there is vdroop, difference between windows idle and windows load, that is why your voltage readings are what they are, the voltage damper on the P5K vanilla doesn't work so you get vdroop. Your cpu will hit your oc speeds when required and drop back when idle, THIS IS SPEED STEP AND IT IS A GOOD THING, mkay, you understand now, if not ask the question in
your thread and I'll reply there
