I built this rig and it runs fine. I can run prime 95 and the Stability Test 5.0 by Jouni Vuorio at the same time w/ good results. I'm OC'ed with the ASUS software which will increase in 5% increments. I'm at 10%. My Gforce is also OC'ed w/ Rivatuner. My tenps are 30-31c on the motherboard and 40-42c at the CPU w/ both tests running. I've run 3DMark 05 my score was 1455. Compared online at 3Dmarks site it seems to me that this rig should do better. Am I missing something? The ASUS software (I'm in the bios) allows for 30% but it won't boot at 15%. How can I OC more? Is my chip maxxed or does the software lack something?
