Micron D9 and high voltage, electromigration effects

[saaya]

I use my 4-4-4-10 PC-6400 Micron Team Extreems on EVGA 780i/ABIT AW9D Max for some benchs up to 2,425V for 3-3-3-3/800 and 2,35V for 5-5-5-15/1200...

I'm still curious if that voltages could hurt them at Super Pi tests or 3DMarks...

What kind of test should i use to know if they are still alive or degraded?

the best is to write down the exact configuration memtest or some other test passed. then every now and then get back and configure everything exactly like that, and check if the memory is still stable or if it degraded.
and checking if the memory can still run a certain speed with low vdimm is also helpful, some chips show first signs of degradation at low vdimm.

EDIT: keep in mind, if you change the cpu, mainboard, upgrade the bios, the temperatures changed, the psu is diferent... then the results might slightly vary.
from one board to another you will see big differences sometimes. keep in mind that variations do not necessarily mean the memory went bad!
