3500+ (Newcastle) memory controller failure?

[Flyingbig]

Was running it for 3-4 months on an Abit AX8 with two 1 gig sticks of ram running in dual mode until recently when my computer became really unstable and windows corrupt itself and basically i was crashing every hour. To cut a long story short i immediately thought it was the motherboard so i switched to an ASUS An8-E thinking this would solve my problem but straight out of the box it was crashing and i had weird issues and hangs when i was installing windows and drivers etc. until i decided to take out one of the 1 gig sticks just leaving 1 gig in there running in single mode and the compouter is as solid as a rock. I also tried running 1 gig in single mode on my last motherboard and it was solid as well. I am right in saying this has to be down to my cpu and am i right to go out and spend alot of money on a new cpu?

P.S. ram settings are on auto and i tried increasing the voltage to v2.65 as i did on my old motherboard for months without issues.

Just a thought, but have you tested each DIMM one at a time to make sure that neither of them is bad?

Memtest. You may have a bad stick.

As i mentioned in my first post i tested both sticks seperately and they are fine, a buddy of mine is testing them running in dual mode on his PC and all is well so far. I will order a new cpu tomorrow night if no one has convinced me that the problem may lie elsewhere. I hope i am not making a mistake as this would definately be a costly one. Sticks past memtest also.
