AMD Phenom 8650 x3 Stock: 2.3GHz OC: 2.75GHz
I can run it stable at 2.7Ghz with no temp problems but when i try 2.75GHz i get BSOD within 10 mins. and at 2.8 or higher it wont start up. Im pretty sure my ram is overheating because when i get the BSOD my cpu temps are below 50C usually around 40C.
Try upping the voltage a little more?
