Hello, I hope there's a guru out there somewhere that can help me. I've just recently upgraded my PC with an Asus P8P67 PRO motherboard and Intel Core i5-2500K 3.30GHz together with a Noctua NH-C14 cooler. The installation went very smoothly and I thought I'd try out the Auto Tuning/Overclocking utility. This increases the multiplier and checks for stability and using this I was able to reach 5047MHz, it looks like it will go higher, but I stopped the utility at this point. My temperatures are OK, but in order to do this it pushes the Vcore to over 1.5v which is a bit high. I also read that the AI tuning utility has a tendency to overdo the Vcore and that you can generally achieve a similar overclock with a lower Vcore voltage. I like the idea of keeping SpeedStep enabled, so that when the CPU isn't being stressed the system throttles back to around 1600MHz and lowers the Vcore to around 1.2v. I tried adjusting the ATV, Additional Turbo Voltage, setting in the BIOS, but it didn't seem to have an effect. Is there a way I can use the Auto Tuning function and keep all the nice power saving functions, but set a lower Vcore limit for the Turbo function?
