and for me radaja I ran prime95 at 445x9 for two hours and all went well, temps were at 66 100% load, is that abit high? i should also add my puter is about 2 feet away from my heat register lol should i start to turn down voltages a notch now? I appreciate your help as Iam sure raffaele2521 does as well, will be nice to finally get this stable at a 4.0o/c once and for all, what realy made a difference was changing those auto values in bios to normal !!
