Memory failure?

[Ed489]

Dear community,

I'm having some trouble lately with my PC with the following specs:

Intel Core 2 Quad Q6600, 2,4 Ghz
Gigabyte P35-DS4
2x1 GB DDR2 Corsair Dominator, 1066 MHZ PC2-8500 C5 (with passive cooling)
NVidia Geforce 8600 GT, 512 MB
Windows 7 Professional

CPU-Z says for the memory:
Dual-Channel, DRam-Frequenzy: 533,3 MHz and lots of other things like latncys and delays, don't know whether they are important.

A while ago the PC started to crash once in a while with a bluescreen reporting some sort of memory issue.
Now I managed to get some time and started some test: memtest spills errors, Prime95 works fine for CPU #0 and #3, but fore #1 and #2 after a few seconds spills a "fatal error: Rounding was 0.5, expected less then 0.4", and BurnInTest spills "Error verifying date in RAM".

How can I know, what exactly the problem is? I read somewhere, that there could be issues with my CPU, my PowerSupply, my Motherboard or my RAM.

Can anyone help me? I don't want to buy expensive parts if they are not broken...

Best regards,
Ed

You can try removing one slot of DDR and do a memtes for the other one and vice-versa. Or , you can run a memtest with your RAM on another pc. Anyways if you had errors on memtest , most likely is the RAM.
