OT - Computer Memory Issue

[Captain Kwok]

I've endured random re-boots on average of 1-2x per day for the last couple of years with my computer. When I first started diagnosing the problem, I though it was related to a video card-motherboard kind of thing that had been reported with my board. Anyway, after a long time of trying the suggestions, bios tweaks etc., and even getting a new video card - it didn't solve my problem.

Further work revealed that it's memory related. I've confirmed that there is a problem with the RAM system, although not (likely) with the modules themselves. The only test that is reporting errors is the random number test (test 7 with memtest86, or lrand/erand with MS's memory diagnostic tool). I think the problem might be with the mobo's cache - can I disable these guys from bios?
