I got the retail i7-2600K already(D2 stepping), but cannot get it past 4.9Ghz.

4.8Ghz @ 1.35V running IBT about 2-hour (on Corsair H70), motherboard is MSI P67A-GD65.

4.9Ghz need 1.5V, a little unstable, but still can do Vantage CPU test/Wprime 1024Ms easy

5Ghz CANNOT Boot at all...no matter what voltage I applied. Already testing on air , testing a lot of various configuration, for about one week and don't seem to get better result. Still cannot boot @ 5Ghz.

And the most confusing experience, it DOESN'T Scale at ALL with LN2(-130C)...wasted 35L already, no result. Triend the same processor on 4 different motherboard(ASUS,GBT,MSI,Intel), no gain.Not even a 100Mhz increase.Nothing.nada.zip

BLCK Scaled a bit from 104Mhz(air) to 110Mhz(LN2), but clockspeed seems the same (4.9Ghz).

So far, SB = Good for air, nightmare for Xtreme overclocker
