Micron D9 and high voltage, electromigration effects

[mad_skills]

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++

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.

i use to get mad when i lost a d9
so i bought more n more
after i dumped my gigabut board i got no more dead d9 n 10+ sets just sittin waitin for a bro to die but
not 1 of my sticks have been degraded since i went dfi
gave the gigabut board to my son n he got a dead promo stick
its ok he got my redline now

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