Asus Maximus IV + Sandy Bridge OC problem

Hmm, I doubt you can reach 5.8 with 2600k... it seems there is lock at about 5.5GHz - 5.6GHz

Actually there are a few chips doing 6GHz now, you have to play with the skews and PLL to fine tune it in, also temp is critical, some CPUs with the new BIOS will easily hit 5.8 but sometimes at -80C and others at -96C, it just requires a lot of tuning up top.
