2600k on dry ice

[QUOTE=V2-V3;12437]pcjunkie,

I have tested the Sabertooth P67 and love the board, I have not seen any limitation in extreme overclocking w/ LN2 or standard air cooling. I must say Overclocking sandybridge is like playing Russian roulette, I have tested over a dozen 2600K's and several 2500K's all behaved very differently. I saw no gain in over clocking or stability when running at temperatures below 0c. The 2500K's seem to hold 5.0GHZ - 5.2GHz and the 2600K's I tested ranged anywhere from 4.8GHz - 5.450GHz
I can reach the same speed on air as with LN2 @ -160c.

I believe its the limitation of "Internal PLL" core voltage. to get the most out of your CPU you must enable the "Internal PLL Voltage Override" within the ASUS BIOS. there is no way to manually tune this voltage beyond the Enable & Disable setting.

thanks. i had a 5.4 on air then it stopped booting so off to rma. now i mess with something else....

I wonder what killed the CPU, I have a 2600K that has been crunching Prime 95 @ 5300MHz for 2 months now no errors. 1.55V 60c on H20

What voltages values were you using for the CPU Core, CPU PLL, DRAM, etc...?

It was the Mobo. Stopped picking up boot drive on sata3

By SATA3 do you mean the 3GBPs Port?

i am not that big a noob...lol no the 6gb or 3gb sata either one. i kept getting red light on boot device...

strange that the motherboard would not pick up the drive on any of the ports or on either of the controllers, makes me think its a bad drive and or SATA cable.
