My motherboard is a GA-MA74GM-S2. rev. 1.0. I have been told on the Graphics & Display forum that I can purchase a AMD Phenom II X4 955 Black Edition Deneb 3.2GHz 4 x and it will upgrade my system. But Gigabyte seems to have washed it's hands of my board. It's three + years old. All I want to know is if it will support the 125 watt CPU. When I emailed Gigabyte, the sound of crashing silence was all that I heard. No email response. Zip. Nada. What's a home builder to do? I do not want to replace the MB and start over. Just upgrade the PS to 750 watts and plug in the higher speed quad core. My current CPU is a early Phenom, 2.2 Ghz 4x. Does any one out there know if my board will support the TDP of 125 watts? And if I have to update the bios before or after I insert the new CPU?
