Well, to answer my own question, this ram has spd specs of 2.65V, 2-2-2-8 at 200MHZ clock. No other spd speed grades exist on the chip.
So the default voltage of this dimm is above ddr's nominal voltage of 2.5v but not by a whole lot. It's worrisome that the ram has such a high failure rate when subjected to 2.65v.
When I put it in my motherboard, which already has 2 other dimms in it, my msi motherboard made the timings too aggressive and the system was not stable. I had to manually slow down the timings to make the thing run.
