Not really, not without taking it out of service. But in addition to
memory, other things that will cause instability are overheating (do
you have lm_sensors configured and calibrated?), flaky power supply
(not even anywhere near dead, just not well-regulated, if all else
fails you may find it worthwhile to spend $75-100 for a high quality
name brand supply, such as a high-end Antec or a PC Power and Cooling
supply), overclocking (surely not, on a production server). for memory
testing, I refer you to memtest86 or memtest86+.
