If this happened to you with samsung based memory or any other memory chip or you are not sure what chips your sticks use, but they also died at low vdimm, please post your experience here as well, it might not be an elpida hyper problem after all...

please answer as many of the questions below, ideally all of them:
Just quote this post and then add your reply under each question

1.) How did the memory die? Idle, load, reboot?
2.) What exactly happened? freeze, errors, crash, system turned off, system rebooted, blue screen, black screen
3.) What board, pcb rev and bios version did you use?
4.) What speed and timings did you run the memory at when it died?
5.) what speed and timings did you run the memory at most of the time?
6.) What vtt did you run when the memory died?
7.) what vtt did you run the memory at most of the time?
Kingston HyperX cl8 DDR3-2000(First Kit bought with Hypers)
Bought from Newegg(04/02/2009), was very happy to see them in stock as they were the only ones with Hypers in stock @ that time.The sticks came in with my classified(759), installed them and ran them everything defaults for about 2 weeks. Then as I found time to get into OCing, started to play around with my rig, encountered a ton of BSODs(pretty normal while OCing), decided to run Memtest @ 1.68 vDimm, 7-8-7 200 BCLK 2:10, went to bed after 3 successful passes, woke up in the morning to see a ton of memtest errors. The system then refused to post with all three sticks and found out that one of the sticks went bye bye(had to put in 1 stick @ a time in the same mem slot to find this out).

1.) How did the memory die?
During Overnight Memtest
2.) What exactly happened?
Please refer above
3.) What board, pcb rev and bios version did you use?
Classified 759
4.) What speed and timings did you run the memory at when it died? DDR3-2000, 7-8-7-20
5.) what speed and timings did you run the memory at most of the time?
Mostly @ default(DDR3-1333)
6.) What vtt did you run when the memory died?
Somewhere between 1.4 and 1.45(sorry can't remember)
7.) what vtt did you run the memory at most of the time?
Default(1.2)

I RMAed it to newegg and in the meantime saw the Dom GT 8-8-8 DDR3-2000 kits in stock and ordered them.

Corsair Dominator GT DDR3-2000 cl8(My second set of Hypers)
The Dom GT seemed to require lesser VTT than the HyperXs(1.375) and was happy about that, with being LinX stable @ 200x21 2:10 @ 1.65V 8-8-8.So I increased the volts to 1.68 again for 7-8-7, passes memtest and LinX, so did a Prime95 Blend run overnight, only to wake up and see a BSOD(I think it was MEMORY_MANAGEMENT BSOD).

1.) How did the memory die?
During Overnight Priming
2.) What exactly happened?
Please refer above
3.) What board, pcb rev and bios version did you use?
Classified 759
4.) What speed and timings did you run the memory at when it died? DDR3-2000, 7-8-7-20
5.) what speed and timings did you run the memory at most of the time?
DDR3-2000, 7-8-7-20
6.) What vtt did you run when the memory died?
1.375(+175mV)
7.) what vtt did you run the memory at most of the time?
1.375(+175mV)

So, since I was also waiting for My RMAed HyperX, I was running them fine @ DDR3-2000 7-8-7 in dual channel mode with two sticks for a while before my HyperX(third set of Hypers) came in and it came in as DOA.The PC was not even POSTing with the HyperXs on them @ DDR3-2000, although they did run fine @ DDR3-1333.

So sent the HyperXs and the GT back for a refund(Thanks Newegg) and also thought maybe the mobo had bad RAM slots and was killing the sticks and also RMAed my classified.In the meantime I got myself another board(Foxconn BR), another chip(W3520) and another set of RAM sticks(Patriot DDR3-2000 cl8) that had hypers on them.That was my fourth kit with Hyper on 'em.The patriots are the only ones until now that I never had any problem with(knock on wood).

I was also waiting for the DOM GT 7-8-7 kits to come in stock and was able to pull the trigger on them too to go with my classified.I also got a W3540 in the meantime.

Corsair Dominator GT DDR3-2000 cl7(My fifth kit with Hypers)
The RAM and my classified came in and I was running it fine with 200x21 with RAM 2:10 7-8-7 1.65V and alas after 2 days of mild activity(gaming and stuff), one of the stick degraded and it won't POST @ DDR3-2000 with that degarded stick and would work @ DDR3-1333 so I had to RMA 'em from Corsair.

1.) How did the memory die?
No death, just degraded.
2.) What exactly happened?
Please refer above
3.) What board, pcb rev and bios version did you use?
Classified 759
4.) What speed and timings did you run the memory at when it died? DDR3-2000, 7-8-7-20
5.) what speed and timings did you run the memory at most of the time?
DDR3-2000, 7-8-7-20
6.) What vtt did you run when the memory died?
1.375(+175mV)
7.) what vtt did you run the memory at most of the time?
1.375(+175mV)


Sorry about the long posting.
