Check your Gigabyte CPU BIOS defaults on an AM3 AMD mobo. GA-790XTA-UD4 AM3 socket with USB 3 & SATA 3 6Gb/s AMD Phenom II x4 965BE 125W (C3) Artic Cooling Freezer 7 Pro 2.1 It defaults the CPU Core voltage to 1.40V (the original 965BE 140W (C2) ) and not the correct 1.25V that the newer chip requires. But there is a bigger mistake: The 965BE max temp is 62c approx. but the BIOS only allows temp warnings at 60c, 70c, 80c and 90c. I want to be warned before it gets to 60c! I would suggest 45c/50c/55c, etc. I know Intel chips can reach higher temps and that Gigabyte make both AMD and Intel motherboards - but this is an AM3 AMD motherboard. My 965BE idles at 28-32c and on max hits 49-50 when running Prime95 for 5 hours so I have no issue. I also monitor my PC when running intensive apps., just to be on the safe side being a new build. But imagine a novice user with the original stock cooler not getting any warning of over heating until its almost too late! Still An Awesome Board! The above BIOS default issues aside - it is a gorgeous looking board and works a dream. These new mobos look miles better than older ones I'm used to. It truly looks amazing with its sleek silver and blue heatsinks and is future-proof with its USB 3 & Sata III 6Gb/s ports. Go into your local store and see them for yourselves. They are that good!
