I've overclocked my i5 750 to 3.8ghz with 1.24v.This has made the Turbo Mode option disappear.I'd like to run it at a lower baseclock and use the turbo mode function to increase the multiplier.The problem is,I'm not sure how to enable it.

My guess is that you disabled EIST and/or C States.

Turboboost is automatically disabled when you clocked it that high. IF you didn't disable it in the bios, then it will enable when you lower the cpu clock back down to near normal.

Wrong.

I've run my PC at 180 base clock with turbo on, tho for some reason it doesn't read my full RAM. I have my DAILY overclock at 177 base clock, IE: 3.75ghz with turbo boost.

I don't know why going to 180 causes the RAM controller to screw up. I've made a couple threads on it but nobody has any good answeres.

So if I enabled c-states and c1e that would enable turbo.As for your problem,have you tried applying more voltage to the IMC?I would try that.

EIST (aka speed step) and C States are the important ones, I don't think C1E needs to be on.

Yeah I tried many things, it's wierd.
