OK 45 more min woth of prime with no errors. I just added the other 4GB of ram and still doing well. 8gb at 933 5-5-5-15. This is the same as the striker. I havent even tried to tweak this system yet just wanted to se if it could hang. I apears that it can. I'll now install the board in the case and continue. I'm using the 1.1b2 bios and loonyms bios settings here where he was calling me out for downing this board. Thanks Loon! The only things i changed were the vcore and NOT setting the SLI memory to expert. Heres a SS of the 8GB of Gskill.
