Can anyone tell if its the CPU or the Ram thats the issue from a Memtest86 result?

I get some very odd crashes sometimes, i can run games (ie. especially WOW) for hours but then i can get a bluescreen just opening a new tab in a browser randomly.

Thanks for any input. not sure if its worth getting some 8GB sticks to try if its the CPU

Here are the results:

If they are in order, then it would be the 4th stick in the first bank?

12288MB would be 3x4GB

Lowest Error Address0x301D283A0 (12317MB)
Highest Error Address0x303D2F728 (12349MB)

I recall doing this once with a Dell Workstation, can't recall how I isolated which memory sticks were the problem. That is going to bug me.
