Elpida Hyper Graveyard

[Raja@ASUS]

You would be surprised how many run their mobo/ram combo's without a extra fan... and the IOH really dumps a lot of heat if not actively cooled.

Maybe ask which dimm in which slot gave in ? The one of my Kingston kit was the one nearest the IOH. Even though there was an Antec Spotcool directed at the IOH. Ram voltage never was above 1.63 (bios setting of the Gene II), about 1.65 reality... I was just testing 1900mhz and was still working my way up to 2000mhz... RMA here we go... the Corsairs and OCZ's keep on working fab on this board so it MUST be a bad dimm... if I kill another one on in the same slot then it's the mobo...

That would imply that 5-6 motherboards from different vendors are all faulty or users are not savvy enough to cool their IOH (including some non X58's chipsets too). Personally, my IOH is cooled with a Delta and the ram is cooled with another fan over it. I've got a second set going south as we speak - one module does not always map to the OS even though when I got the kit brand new it mapped every single time (this non-mapping thing that was the mark of demise for my last kit). The troublesome module on the new kit was not in the first slot either, plus Im running an open test bed. Cast your votes as to what it is, my guess is we'll never find out the truth on this one so can only speculate.

Also strange how if it's the mobo the non Elpida stuff carries on working even when substantially over-volted on the same boards. Whichever way you look at it, it's quite an Elpida sensitive affair. The IMC setup process on i7 is largely automatic too (no documented drive parameters have been found for those wondering about those next) - not much any of the board vendors can do in that regard. The rest; the ony real stipulation is that the VTT line is fully up before Vdimm is applied. In terms of power regulation they're virtully the same Vdimm circuits we've had on some boards for the past 18 months, no major changes from companies like ASUS. One wonders why these 'faulty board' issues did not show up in the past.
