Micron D9 and high voltage, electromigration effects

[koli.fx]

Guys,

I don't think it is the voltage killing these chips. After first two kits of my Ballistix 6400 died (ran @ 2.2v 4-4-4-12 @ 800mhz for 5 months) I thought it was due to my Maximus overvolting. So when I got replacement kits I tried to find lowest voltage that would run 4-4-4-12 @ 800mhz. I started at 1.8v (in bios), upping until 1.86v. At 1.86v my 4x1gb modules would pass the memtest so I left it like that.
These modules are meant to run at 4-4-4-12 @ 2.2v. I got it running @ 1.86v. I don't care how much my Maximus overvolts, it does not matter because I got my ram to run at latencies and frequency as specified by manufacturer at the lowest possible voltage. I hope it makes sense.

Now after just TWO months, one module out of those two replacement kits is dead too. It never ever EVER ran above 800mhz or 1.86v. Second kit runs without problems @ cas 4 @1.86v.

Also I would think that Asus Maximus is using high quality voltage regulators.

I RMAed the bad kit (thank God for brilliant customer service at Crucial). I am considering getting something else. Can you tell me what manufacturer doesn't use D9? I am thinking about going with OCZ Reaper. All I need is ram that will do 1000mhz (I will get C2D 8600 soon) and won't F***ing die in the process.

Thanks.
