hi guys, built a brand new pc with the A10 5800k and is getting poor graphics aero WEI score of 4.8, gaming is 6.1. ram is running 1600mhz dual channel properly and I cannot get it higher for the life of me. 13.12 drivers and running win 7 ultimate 64 bit. My friend has the exact same build and specs and getting 6.2 in both aero and 3d gaming. Also everytime the cpu is under load, there is a moderate buzzing sound coming from it. Sounds exactly like a tattoo gun but not as loud. No sound when idle, but sound anytime the cpu is doing anything. I've tested it with a rolled up sheet of paper so I know for sure it's not the fan nor psu nor harddrive, comes from the cpu. It's not coil whine. Thoughts? Do I have a faulty APU?
