Unless you run your cpu as a dual or tri-core I wouldn't go past 1.55v for long periods of time. I did 1.6v for my old 955 C2 and it fried my board's VRMs after a few hours. The CPU still survived, but I had to RMA my board.
Your board has better VRMs than mine though, so you're less likely to see the same result as me, but I recommend going for a lower overclock as 100-200mhz doesn't add much in benchmarks/gaming.
Thanks, I've taken my overclock off for now due to such high voltages being needed (or at least being shown in CPU-Z), however it is my ultimate goal to get to 4Ghz as a 24/7/365 overclock.
I have been watching the temperatures on my VRM's whilst I have been overclocking and the highest my VRM's have gotten is 30C so im not too worried about those. I think my processor prefers high voltages as dropping it down to stock isnt stable when running an intel burn test but with high voltages it is.
Im going to try overclocking my other components to max first and then push up the processor last, but at least i know the H60 is able to handle the heat from high voltages (up to 1.60v) and a 4Ghz clock speed, it didnt even pass 58C on load. Its such an amazing cooler, i cant even hear it over my idling graphics card.
