this ram took me 30 seconds to install and it works beautifully out of the box. You can customize the lighting with a software if your mobo has that capability. It is beautiful and runs smoothly with no issues. 10/10.

They came with different chips. One pair works fine still (S820M). The other pair (S821M) died in 2 weeks and I had to rma with g.skill directly. They sent me different chips again (S820C) which are regarded as the better chips.

The RAM works just like it's supposed to. The only issue I encountered was that the BIOS tried automatically overclock it to 3800 MHz. All I had to do to fix it was to change it in the BIOS. My system runs alot better with 64 GB of RAM in it.

I treated them like Micron E Die and got a decent little bump to 3466 with fairly tight timings and hardly any extra voltage. Each stick is Dual Rank as well...Gives better results than, say, using two kits of 32gb which would undoubtedly result in quad rank and harder to overclock. As well two of these kits could make it to 128gb at stock xmp most likely just fine.
