Vista 64 Windows Memory Diagnostic Tool - False Negative

Vista 64, Asus P5E v502 bios, Core 2 Quad, 4 gb crucial RAM, No over
clocking, standard ram speed,

I have been getting intermitent blue screen of death. Afterward my machine
warm boots, and often I receive Bad Bios CheckSum error. I power all the way
down and then power on and boot no problem.

I tried running the Windows Memory Diagnostic Tool. It came up with a
problem, but didn't identify which stick. I pulled one and reran, everything
was OK. That was a bit of a cooincidence. I tried putting one of the other
chips in the slot the one I removed came from, still OK. I put all sticks
back and the diagnostic ran clean. I thougth I dodged a bullet. Sometime
reseating will fix these things.

I came home after work and sure enough Bad Bios Check Sum. I powered off
rebooted and ran the mem test and it diagnosed a problem.

Is this bad RAM, bad MB, or bad bios?

TIA

If you are running pc6400 ram with 4x1GB dimms, try dropping the dram speed
to 667 and see if you continue to have the issue.

Correct - 4 x 1 GB DDR2 800 Crucial Ballistix (PC2 66400)

Thanks. I will give it a try.
