Overclocking advice

[mshaw03]

Today is the day I delve into the world of overclocking.

Got an i5-3570k and a z77-d3h.

I've just bumped my multiplier up to 40 as a starting point and core temp is giving me a max temp of about 68c under load. I've also disabled the turbo boost thingy.

What sort of increments should I be using from here?

How long should I stress test for and which is the best test to use on prime95?

Is there any need to touch the voltages yet?

Thanks.

Cooler is an Enermax ETS-T40-TB.

Gonna test at 4.2 for temps and stability.
Then 4.4.
Then 4.5.

Ok I'm up to 4.4 but 3dmark crashes on the combined test where it would continue whilst I was at 4.2.

Should I start to increase the volts now?
Are there any other settings I should be changing?

I just ran 3dmark at 4.2 and max temp was 57c.

I'll go up to 4.3 and see what difference that makes.

Sleeping Dogs crashed after about 20 minutes at 4.4 too.

EDIT: Just tested @ 4.3 and 3dmark crashed again. Max temp only reached 47c. Any ideas?

Cheers Chris I'll try that next time.

In core temp my vcore seems to be at about 1.48 under load. What's all that about?
