Z68XP-UD3P frying my RAM

[allenwr1505]

So I have a GA Z68XP-UD3P v1.3. I used the old F7 BIOS and I ran 16GB Corsair RAM at 1.169 QPI/VTT and 1.55V Vram. Ran it fine for over a year. Then I update my motherboard BIOS to the new U1e UEFI BIOS. I use the same voltages. A few weeks later one of my memory sticks dies. I think nothing of it and get it RMA'd with a whole new 4-stick set. However, now 2 months later it's happened again. One of my sticks died. Ran Memtest86 and just one of them went bad. I'm not sure if it's the same RAM slot. It was the 4th RAM slot this time and last time it was either the 3rd or 4th RAM slot.

Any comments? Is it my QPI/VTT voltage? A Vram of 1.55 should be well within limits. It's normal to have to bump up from 1.50v with a 16GB kit.

dram voltage is fine anything from 1.5-1.5750v is within intel safe limits,ive seen folks use 1.6v and more

for qpi/vtt 1.2v is the safe limit although due to no bclk overclocking its usually fine on auto/stock 1.05v

if i were you id flash back to the previous bios,could just have been coincidence?

Dude, it's only that one stick. Errors everywhere. Other sticks are fine, no matter what slot. That screams bad memory. Something killed it. Two single sticks dying in a row.

True but you still can't rule out a coincidence,could be a loose ram slot/connection I've had that happen where its shorted and blew a ram stick,all you can do is rma the kit for another and continue to use them but keep an eye on things,if it blows anymore ram then id rma the motherboard
