I ve been using AMD overdrive to raise the bus speeds and increase voltage, but it hasnt worked out well.
How important are memory timings when over clocking? Also, the PSU is a cheap one, could that be the source?
The operating temps of the processor/board are far from overheating. The processor hits 45 degrees under load.

Did you lower the RAM multiplier, if not its most likely the RAM cannot handle the speed.
Hi docfeelgood and welcome to Tom's forum.
1- Don't use AMD overdriver to OC. 2- Always OC from the BIOS. 3- The 635 is a locked CPU that means that u can't change the multiplier CPU to rise or drop the speed of it in that case u need OC with the FSB (bus speed as u call it) but rising the FSB u also change the RAM speed because both are linked. The 1st thing that u need to do is slow down the RAM speed to 667 after that u can start to rise the FSB.
Don't forget test the stability of the rig with prim95 3 hours, OCCT 2 hours or LinX 1 hour because that u can boot or log in doesn't mean that the rig is stable.
