I could say "ditto," but even recently a 4x4 Corsair XMS3 DDR3-1600 kit came into my hands. I didn't bother overclocking it, except that you can set CR=1 and it passes a day's-worth of HCI Memtest-64 -- without changing any voltages. Well, to be honest, I DID bump up the VCCIO to 1.075V from ~1.005.
I replaced that kit with a G.SKILL Ripjaws X DDR3-1866 9-10-9-28 kit -- cheaper than the 9-9-9-24 Ripjaws Z kit I have in another machine. The former seemed like a bargain at ~$80+. Also solid RAM.
I like G.SKILL and have been using them since 2008 -- replacing some Crucial kits that burned out in less than a year as what seemed to be an epidemic of "too-optimistic-voltage-spec -- itis. "
G.SKILL tech-support has, over the years, answered every question I put to them in e-mails. Always very helpful. I'd had the "PQ" DDR2-800 kits, the Black-Pi 900's, another PQ DDR2-1000 kit, DDR3-1600 Ripjaws, Ripjaws X and Ripjaws Z.
I'd had one or two out of maybe eight DDR2-800 modules go south, and the RMA turnaround seemed warp-drive fast. Or at least the delay was much less than you'd expect. Everything else was flawless "from the git-go."
