Pros: Extremely Fast, Highly-Binned, Tight Latencies, Dual-Sided DIMM's, Low-Profile for Air-Coolers, Black has a Universal Appeal, OVERCLOCK VERY WELL
Cons: Trident X is better for pure speed, many LGA2011 chips do not have strong enough IMC's to take advantage of the speeds available with this kit
Been running this kit for some time, having originally purchased it in late March/early April of 2012.
When I bought it, I expected a kit of 16GB DDR3-2133 9-11-10-28 1.65V memory, but I got far more than I paid for! Due to having purchased the kit so soon after release, and before it was "popular", I lucked out and got some very, very strong IC's. Combined with a 3930K that has no issue with RAM above 2400 9-10-10-27 1T with just 1.115v VCCSA and 1.110v VTT1, and I've yet to get bored with tweaking this memory!
Stock speeds are MORE than fast enough for 99% of people, here's a few benches showing what it'll do:
And with just a small amount of tweaking (command rate 1T, RAM frequency bumped up slightly via BCLK of 103.1)
Here are a few different benchmarks, some stock, some with a slight boost in frequency (~DDR3-2200 with stock timings and 1T command rate)
This memory has done up to DDR3-2584 10-12-11-32 1T with just 1.665v vDIMM, 1.135v VCCSA, and 1.1325v VTT1. It'll go even further in the 3770K/UP7 setup, but this is my X79 RAM and I have Trident X 2400 9-11-11-31, 2666 10-12-12-32, and 2800 11-13-13-34 for that rig
All in all, for $125-170 that this memory retails for, it's some of the best out there, period!
