Ok, so I have an update. I got my 16GB Kit of 2133 RAM. But before installing it I decided to put in another 8GB of the Vengeance 1600 RAM to see if it made a difference having two sticks in there. Low and behold the performance improved massively. My 3DMark 11 score was now getting in the 1500's. So then I decided to run the 2133 RAM. The performance went up slightly, into the 1600's. But then the motherboard died. I have no idea why. So I ordered an Asrock FM2A75-Pro4-M. Now I have a new problem. When I run the RAM on Auto setting, it defaults to running at 1333MHz instead of 2133MHz. It runs fine, just at the lower speed. Now, if I set XMP or try to set the RAM to 2133MHz in any way, the PC will run Prime 95 and then shut down after about 5 mins or so. Somehow, by setting the RAM speed, it also seems to be increasing the CPU voltage. I tried manually setting the voltage lower but it still seems to go up under load?
Any ideas? Should I just forget Asrock and get an Asus board?
