Memory Timing Evaluation Tools

[Jason]

set the BIOS to SPD which is auto for timings. You might want to try Prime95 which does an exellent job stress testing machines and ram. As far as specific ram timing testing tools there are'nt any outside of an expensive stand alone ram tester which im sure you dont want to get.

Additionally you may want to set the bios back to defaults entirely. If the instability continues in all of the machiens then it would be my suggestion that there may be a software issue going on and not a hardware issue unless these machines are in a hot environment or very old which if they are using DDR ram they are probably not. Give them a good blow out using canned air.
