RAM thrashing program?

Does anyone know of a good program to stress-test the computer's RAM? My Windows drive currently bluescreens every time it tries to do something RAM-intensive (0x7F UNEXPECTED KERNEL MODE TRAP), but MemTest86+ has been through 13 passes and not found any errors yet*. I suspect it's a stress-related memory fault, and I'd like to try stressing it on my Linux drive to see if it's Windows-specific.

I'm running Mint 10 GNOME 64-bit.

*It's still going: I left it overnight and I'm at work now. After 8 hours, though, I doubt it'll find anything in the next 11.

if MemTest isn't finding an error after that long, I'm willing to bet it's not the ram, but windows has corrupted itself.

You can get memory errors like that from other hardware faults too. I regularly got memory errors from overheating, as my heat sink wasn't very good. My computer would overheat and try to do some weird memory copies, crashing Windows. Since most CPU intensive tasks are RAM intensive too, there was a tendency for the system to crash during copies. It all fixed itself once I changed the heat sink. It's worth keeping that in mind, if you start to doubt the link with RAM.
