Micron D9 and high voltage, electromigration effects

[Xtreme Addict]

they still do 1200++

There are three symptoms of dead D9:

1) boots with higher voltage than 1.8v and overclocks the same as earlier
2) OC is lowering drastically (degrading) but still boots with 1.8v
3) they are unstable - errors in memtest etc...

*Rarely but from time to time memory with D9 after some coincidence (high voltage & overclocking/after psu broken etc.) doesn't boot at all

Symptom 1 & 2 often appear together but not always. Symptom 1 & 3 are the most frequent. Memory with symptom 1 often may work for years with slightly more degradation effect or even no. Memory with symptom number 2 is going to die definitely. Memory with symptom 3 aren't good for working 24/7 and memory qualifies only to RMA

That's from my experience
