Well it first started off when I noticed that my CPU wasn't ramping up past it's 1600Mhz idle clocks. Okay fine poke thru the BIOS redo the OC should be fine. Nope no change there either, so of course next step is to clear the CMOS and start fresh. Well here is where it all went weird. Now in the BIOS it won't OC at all. Normally I would have the option to change my Multi. That option is GONE. I can't even select the XMP profile for my RAM(1600) that now comes up as overclock failed on restart. The CPU ID's correctly in the BIOS(2600K) but yet I am offered no OC options. I have tried reseating the CPU twice just to be sure(PITA on watercooling) Yet nothing changes. I have even attempted to reflash the BIOS with the latest. I mean it seems to be running fine at stock clocks but I have lost the ability to adjust the Multi. It's like it has forgotten it is a K series CPU.
