|Most of your components are quality goods. However, the Hitachi is not. Putting that drive in a RAID0 array with the raptor is, at the least, dragging the raptor down. Could be the cause of the lockups to. |
I suggest you run the OS on the Raptor alone and use the Hitachi for backups or data. That is all it is good for.
Running an array that far out of sync is just asking for trouble.
I would be the system would be faster with the Raptor alone than it is now.
Also, you should configure the RAM manually. That RAM uses way more voltage than JEDEC specs of 1.8V. I think you should be running your RAM at half the CPU bus speed (1333).
Your PSU has plenty of juice but you should still balance the loads. You have 2 12V rails. Use the power connector that goes directly to the motherboard (4/8 pin) off one rail and the graphics card off the other.
Your CPU draws 95W (7.92A) & the graphics card 108W (9A)
