IP35 & Q6600 Flappy Overclock

Denrok · 5 Sep 2011 at 15:07

I'm running an Abit IP35 and just picked up a Q6600 G0 stepping cpu.

I've clocked it at 333 x 9 however CPU-Z shows it's constantly changing from 3006.4 @ x9.0 to 2004.2 @ X 6.0 any ideas what could be causing this?

speedstep? powering down when less demand?

boot into bios, and disable C1E, EIST etc... basically any energy saving

also some settings for your cpu and board, for 3.6ghz, just watch your temps dont let it go higher than 80.C running prime95.

Why disable energy saving features?

The processor will ramp up to 3GHz when needed.

Denrok, leave things as they are. The CPU is downlocking when idle to save electricity. It ramps up to 3GHz as soon as you need it.

+1 to this, my 920 is clocked at 4.2ghz, got speedstep enabled as i dont need that sort of power for web browsing.

j.col most probably means when stabilising overclock.

Personally when I try to overclock (stabilise) my cpu, I always turn off power saving features. In my experience they tend to mess with voltage/current reaching the overclocked cpu, hence making it crash.

Basically the philosophy goes that nothing should be obstructing the cpu during overclocking.

Once we have a stable overclocked cpu, then we can turn back the power saving features :cool:

i always disable them, until i know its stable, then enable them again.
especially if he can get it higher than 3.0ghz
iirc, some of the overclockiing guides i have read, recommend this,
even the link to clunks' guide above, has them disabled for now,

and thanks wingzero30

Don't confuse modern day Sandybridge and turbo/multiplier overclocks with older CPUs.

On a Q6600 SpeedStep etc may make an OC unstable where it would be stable with such features off.

Find a good clock with everything off, try keep the system stable with it on and bonus, if not - That's life
