Sorry for asking stupid questions, but this is not something I've ever played with. What do I look for, and what should I change it to?

First question is: what kind of memory are you running? A link would be good if you have one.
And I am curious as to your MB model number too.
I have this RAM x2. And this is my MoBo.
I'd love to hear what you did to fix your issue...
The stock timings are Ummm... well.... I don't know. The overview has it listed as 8-8-8-21. The details page has it listed as 8-8-8-24. Use CPU-Z and check the memory tab it will tell you the timings. Then check the SPD and it will tell the timings which are supported.
Ok, I too have a Gigabyte MB so I am hoping that we have pretty much the same BIOS. Boot up computer, get into BIOS. There should be something labled MB intelligent tweeker. Enter that. Then there should be something labeled DRAM configuration. Enter that. There should be something labeled Timings and it is probably set to Auto. Switch it to manual. Now below that should be a tab labeled CAS timings. If it shows a 7, change it to and 8. If is shows 8, change it to a 9........F10 and reboot. I hope this made sense to you. If not, ask more questions and we will continue to work on it. Good luck.
Memtest: Not sure what win7 uses to do that. A good memory test can be run from a CD, and will usually take a day or two depending on the amount you have.

Ok - with 8 Gigs of DDR3, the Memtest embedded with windows took 4+ hours.
Something is telling me that joker is either right, or on the right track...
I went and changed the memory settings in BIOS, and I'm at the most stable system I've had in the last week. I have both 5970s in the machine in Crossfire mode, running at stock settings.
With memory clocked back to 1066, at 7-7-7-19, I've been running MW for the last couple hours without incident. I tried putting it on Collatz at these settings, and it crapped out - but MW is running well so far.
Any thoughts on the next settings I should try or anything like that?
My only last thought is to clock it back to 8 since that is what it is rated at and see what happens.
