Mine died couple nights ago. It was the 1866 c7, Same chips. 1.68 volt left computer on over night woke up next morning and it was crashed and wouldn't boot. 2 of the sticks died. The first kit I had had 1 stick DOA and had to RMA. That's two sets in about 3 weeks.

I am going to see if I can get a refund. Luckily this all has happened within the 30 days from purchase but i'm not sure if Newegg will give me a refund.
