Micron D9 and high voltage, electromigration effects

[Revv23]

Obviously. But what I am after is the influence of electromigration in other ICs aswell, not jsut DRAM chips.

Are DRAM chips more vulnerable to damage caused by electromigration? If the required current is defined by the frequency, wouldn't these high clockspeeds(+4GHz 24/7 use) and thus high currents flowing trough CPUs kill them very quickly? Or are CPUs just much more resistant/durable by default currents and temperatures? Could have alot to do with manufacturing process and methods (high-k & metal gates etc.) used.

you are correct it applies to all IC's ever. Even chips run at stock speeds have a limited life. adding heat, mhz, and voltage simply speed up this process. There are sweet spots that won't shorten the life of an IC too much, which is what most people run thier 24/7 overclocks at.

yup exactly best findin the sweetspot
i run 1200+@2.0v if i run cas4 1000mhz i need 2.22v
every stick is different some sticks prefer 1000mhz cas4 cause they need 2.3v to go 1200+

In my experience D9GKX tend to do CL4 overclock really well while D9GMH are better for CL5, meaning they need less voltage for CL5 and more for CL4 than D9GKX.

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

[mad_skills]

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
