Hey Stepnoz check the threads you can update the 2nd BIOS to the new one as well so you don't have to mess around with the dual boot PITA... Use a PS-2 keyboard and hit Alt+F12 when you turn it on.... :thumbup:
Batch report on 2600K.
#0584 batch L045A998
5.00ghz. End of story.
No valid because not worth it.
103Bclk not stable but bootable max.
Didn't like over 1.6v.
I'm afraid not on that chip unfortunately. Wouldn't get past post at even 51x and 101bclk while last CPU did 103bclk maybe more but was limited to 5.1ghz....
Another two chips on the way... Crossed fingers for 5.4ghz or better.
