Speedstep with an OC

JIM_BOB7813 · 29 Jun 2007 at 13:11

Is it ok to use EIST and the other one (C1E?) with an overclock? Is there any way to program the EIST? Is it intelligent enough to adjust the vcore to suit the clock speed or does it treat my chip the same as if it was at stock speed?

I have an E4300 at 2.4GHz on stock volts (1.296). I'm thinking that because this chip is running at E6600 speeds then it will be ok to use speedstep and it will still be stable?

Someone said that they use RMclock to do this but i'd rather use EIST/C1E if possible.

Thanks

I thought that Speedstep just reduced the multipier when the CPU was at low load.

If it is stable at the 6600 speeds then it should be fine at the normal speed.

I remember Speedstep dropping it from 1.8GHz x9 multi and 1.3v -> 1.2GHz x6 multi and 1.0~v
C1E is the routine which drops the vcore from 1.3v to 1.0v, speedstep does the clock speed.

TBH i would probably stick to the BIOS options, C1E and Speedstep really as that is what they are there for.

Keep mine off as havent had to touch the voltages on my OC and the temps are acceptable.

ok thanks
