Feb 22, 2012 7 0 0 I just finished up my first OC, that i judge successful at least. I was attempting to OC to 4.00GHz on my i5 2500K. I tried going up to 4.5GHz with little success and decided all i need for now is 4.00GHz (may try to work my way up eventually, but for now i just want to game). Listed below are my system specs, BIOS settings, and CPU-Z screenshots. I tested this OC with Intel Burn Test and Prime95 and these results/temps/voltage readings are listed below (sorry for the lack of screenshots for these tests). I have been running this OC for about a week now with no problems whatsoever. From a practical testing standpoint, have ran Skyrim heavily moded for increased visuals,etc. and on Ultra settings with no problems and at a good performance level (no other games as of yet). My voltage Max has never gone over 1.28V (according to CPUHD and HWINFO64) while playing games and generally using my computer at normal load and my temps are usually around the 30C range. My voltage normally is around the 1.26-1.27V range under normal conditions. So basically, is this a good OC? What do you think? If the forum could review my settings and give any advice/suggestions i would really appreciate it. Thanks!
