BSOD happens randomly BUT only when additional new ram installed

[Siggers]

Hi There,

Im Adam, from the Gold Coast, in Australia.

I consider myself a relatively knowledgeable person whilst dealing with PC's, however this has me stumped, so I hope all the extremely bright people can help me out.

Windows 7 64bit
Retail version, installed about 6 months

I built the computer for my wife, and was awaiting some items to come into stock, so I had only 4gb of ripjaw ram when first installed everything, and everything ran perfectly.

I got my second lot of ram an additional 4gb of ripjaw ram, same model and mhz rating, however once installed BSOD appeared time and time again, I couldn't track down the problem, I ran mem tests, and came back that there was some errors, I took all 4 sticks back and had them replaced, one set was exchanged on the spot the other took about 2 months, so cruising along on 4gb of ram again, and all is well, receive my additional sticks, and within 2 minutes of loging in, BSOD...

The Motherboard has 4 slots, and is compatable with this ram, the slots are colour coded, blue and white (from memory) and the pairs are in the own colours, pair 1 in the blue slots (1 & 3 slots) and pair 2 are in the white slots (2 & 4 slots), once i pull the additional ram out, back to normal.

Could this be a Motherboard issue?

I have attached the files to the post

Any help would be greatly appreciated...

And if you swap which pair is in which color--problem still exist?

If yes, then:
Remove one set and Run Memtest86+
Swap set out and run Memtest86+ again.

If both sets pass, then put all four sets in and test again.
If test fails, then RMA the board.

To be honest I don't think I have tried swapping the pairs around, however I will do that shortly.

Thanks in advance.

What is the status with swapping the pairs? Have you had a chance to do so?
