Official MSI P7N Diamond (780i) Discussion/Review/Overclock/Guide/BIOS Thread

[Mannekino]

Hello,

I need some help overclocking my current computer. I'm running my setup @ 1400/800 now and it is completely stable. I'm unable to get it past 1500/750. I would really like to get my system stable at 1600/800 settings (this is my target). Any suggestions on how to achieve this? I'm a bit at a loss with regard to the voltage settings. Here is all the information with regard to my computer. I have read quite a few topics on this forum and also on several other forums. It seems that most people get excellent results, but that is not the case for me so far :cry:.
