However, OP, Did you or did you not operate the RAM at 1866Mhz? Or did you simply plug in the RAM and, by default, it operates 1333Mhz@1.5v and 2 weeks later, CPU dies?
To me, OP stated that the RAM operates at 1333Mhz at 1.5v by default and OP did not change that although OP does have the option of using XMP profile which will overclock the RAM. The reply from Intel was that even though OP did not willingly overclock/overvolt, the mobo will indeed operate the RAM at a spec beyond CPU specs as soon as it boots. Although bios is smart enough to downclock after the first POST, the damage is already done and therefore voided the warranty.
My MIVEZ did/does.
SPD/XMP settings for the ram is 1.5V across the board, no hint anywhere that it should ever run at 1.65V.
And yet my mobo defaults the ram to DDR3-1600 (out of spec) at 1.65V (also out of spec).
It ran like that for a couple weeks before I realized it.
It is Intel's fault? No.
Is it the ram guy's fault? No.
Is it the mobo maker's fault? Yes.
As is the case with all things liability, determining the party responsible for the liability is standard operating procedure.
That is why Intel deferred the OP to Newegg. Newegg owns the rma responsibility (and cost) until their pre-agreed window expires.
I can't tell if people here just don't know how the world works or if they just don't want to accept that it works no differently for Intel than for Toyota.
I have a 100k/12yr warranty on my Toyota, but I don't call Toyota for warranty work, I coordinate it through a privately owned toyota franchise dealership.
If that dealership chooses to not honor the warranty then its time to go to Toyota direct. But if I choose to go direct to Toyota I can't exactly be surprised if they redirect me to the nearest Toyota dealership to have my warranty issues addressed.
This thread, perhaps unsurprisingly, is becoming a mountain out of a molehill based on semantics.
