Trying to get 200 BCLK 20x unstable on i5 750?

[Grizzly]

Hello again, decided my last topic was too general for anybody to help or give advice so taking it one problem at a time.

So to the best of my knowledge most people can get 4GHz on an i5 750 with a 200 BCLK, 20x multiplier and 1.4V.

However I can't, is it possible I've done something wrong (first overclock) or is it more than likely I have a below average chip?

Can you please post your full overclock details up for us dude. Might be easier to take pics of the bios. We'll need frequencies and voltages please.

Sorry, thought I was missing something when I posted this, here's some pics of whats in the tweaker, CPU configuration and RAM timings.

After an evening free to tweak it seems fiddling with with the CPU Clock Amplitude + Skew, Load-line calibration and CPU Spread Spectrum has solved my problem when running OCCT Linpack for an hour, chances are that Prime95 will run without errors as well now, will still check with a long-ish run tomorrow.

Case closed that's worked, now perfectly stable 4GHz, at least this thread is here for any other newbie overclockers who come looking for help from google
