hey folks, just got myself an I7-2600K after spending eons in the AMD camp, but there's a couple of things I'm uncertain about with this chip.. so hopefully some of you experts out there can point me in the right direction.

After reading how straigtforward it was to OC these chips I had a looksee, and following the advice on this forum set about making a few tweaks..

Leaving BCLK at 100..
Upped the core voltage to 1.350v
Upped the memory voltage to 1.5v
Increased the CPU multi to 43x.

This should give me a ballpark 4.3Ghz OC correct?

When the CPU is under load, CPU-z does indeed indicate it as running at 4312 Mhz... however, as soon as the PC has finished doing whatever it is meant to be doing it drops to 1604 Mhz... which appears to be it's default setting at idle.. is this normal?

Am correct in thinking that when you're OC'ing these chips you're effectively just pushing the Turbo Core limit higher, and the drop back down is part of the normal operation of the Turbo system?

Is there anyway of turning this feature off? Or should I just leave it alone?
Is there anything else I need to be looking at with respect to OC'ing the chip?

Cheers..

Downclocking to 1600MHz when idle is perfectly normal.

It's an energy saving feature, Intel SpeedStep.

Leave it alone.

As you've seen the processor clocks back up to full speed as soon as you need it.

Righty, spent the day with my new build.. and to be honest, I can't seem to get stability. Now I'm not sure if it's the OC that's been causing the problems or something other, as I've been installing various bit's and bobs throughout the day..

But I've had about 5 BSOD's, and several general system freezes during the course of the day.. and that's about 5 more BSOD's than I had in the whole of the last 12 months with my previous build :/

What is an 'acceptable' OC for an I7-2600K.. using a corsair H50 cooler btw, and core temp indicates normal temps around the 38-40C mark.

I've currenly wound back from using a 43x multi, to 40.. to see how it goes. Should I be able to push it further?
