at 3.4v these memory still can be smoking hot, I was running 265 @3.5v the other night and I have a Thermaltake 4800rpm (75cfm!) fan blasting on my redline at full speed but after an hour of 3dmark loop the heatspreader were still kinda hot..especially dimm 4 right next to the cpu, make sure you have sufficient cooling on these ram but if they still died atleast we would know heat didn't causes it.
