Hello, this really grind my gears:
if tried all kind of combinations in fixed/offset/multipler but he wont get me stable above 4.3 ghz all other clocks i can reach by offset - or + voltages but if i reach 4.3 it feels like bios or system is block it, does someone know about it?
i can run 4.3ghz @ offset -0.025 but the only time i managed to reach 4.5 ghz it was with 1.45V fixedmode with bluescreen after 2min windows... i didnt raised Voltage higher because its insane

Unfortunately, you hit the wall for the CPU. Nothing to do with BIOS or MoBo. The limitation you are seeing is from the chip itself. It's the pick of the lottery. You don't know what type of chip you'll get until you play with it.

Me, I personally couldn't push my i5 2500k past 4.3GHz. I have temp problems with my i5 3570k going past 4.1 GHz. Personally, I don't think I'll push it anymore than where it's at as there's no real gain from the minor speed boost.
