I've been so focused on the Gskill 5333Mhz Hynix kit and the outstanding responsiveness it offers my work apps, not to mention the insanely fast boot times of 4.5s-5.0s, and still planning on tightening up the other primary timings with that kit from XMP other than CL, buuuut. Before I got the Gskill F4-5333C22D-16GTES kit, one month prior I had the Gskill ultimate b-die F4-4800C17D-16GTRS kit, which is also a beautifully performing mem kit.
If you prefer b-die or if your apps/games prefer lower latency vs superhigh memory clocks, this kit will make you extremely happy.
It runs 4800Mhz 16-16-16-37 and the outstanding 5066Mhz 17-17-17-37 profiles with ease on the Maximus XIII Apex board.
I've even run the kit way down in gear 1 3866Mhz CL14 briefly, a wonderful mem kit.
At 5066Mhz CL17 the Read Write Copy speeds are brilliant.
