Bad Intel DQ965GF motherboard? Fails memtest, but memory is good

I've got a machine with a DQ965GF motherboard. Two days ago it started locking up hard. Ran memtest 3.3, 1.7, and TestMem 4. TestMem just freezes, memtest failed on moving 8 bit inversions. Letting memtest run eventually causes the system to restart.
