I'm having a problem with a system I built. It's only the second one I've built so I want to hear the "I know it's stupid but did you check..." type of questions.
The problems:
1. the speed of the cpu varies. From 1.999GHz to 2.666. It never gets up to 2.83. I have EIST disabled in the bios and the dynamic energy saver stuff is off. This is according to cpuz and other utilities. They agree on the speed. The speed does increase under load but never above 2.666. Then when idle it drops down to 1.9999
2. I can run one instance of prime95 on any core and it is fine. I can run 2 instances on any two cores and it's fine. But when I start the 3 instance the system locks up solid. I have had all cores loaded around 80% doing other things. I can run 3dMark06.
3. I'm trying to use a raid setup but I can't get into the raid setup bios. On screen it says <ctrl> <I> but that does not work. Hit it once, 20 times or hold the keys down constantly.
The temps dont seem out of line. Idle the cores are 36,32,38,28.
The system:
Q9550 E0 stepping, GA-X48-DS5 mother board with f8a bios, Corsair TX 750W ps, Asus 4870X2 TOP graphics board, 8GB OCZ 1066 memory, Vista X64, cosmos case with 4 fans, version 8.10 of CCC
Anyone have any thoughts?
