Micron D9 and high voltage, electromigration effects

[Alex-Ro]

Well it depends,mine D9GMH will do 1000 cl4 with 2.08v and 1200 c5 with 2.1.

I am aware of that, i just mentioned that D9GKX tend to o/c better with CL4, i've even seen some D9GKX kits that do 500MHz 4-4-4-4 on 2.0V or even some tenth of a volt lower.

my d9gkx wont boot under 2.1 they really like the juice

I guess you are referring to the HyperX kit?
Yes, they do need some voltage and are known for that, some ppl here have tested it and it's the case with a lot of those sticks.
However, Cell-Shock, Team Xtreem and Ballistix/B.Tracer that have D9GKX ic have less vdimm need with CL4 overclock.

Because they are DEAD/BROKEN

Because they are DEAD/BROKEN

they still do 1200++

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

I really hate when kits degrade, that's the worst possible thig. When they're dead, that's it. This is far worse.

If it won't do in this case 800MHz CL5 for D9GKX with 1.8Vdimm, then its dead in every way.
