I've been going crazy buying MFR since I moved to the Haswell platform, having had excellent results with some low binned Patriot Intel Extreme Masters 1866C10 (pushed to 2933 C12 with 1.85V+). I really liked the look of the Vengeance Pro but all the online reviews thus far have had Ver4.21 kits using Samsung 4Gbit ICs, which as we all know aren't stable past DDR3-2550 or so. A local retailer got these in stock, and since the kits are out on the racks you can check the packaging for serials, etc before buying. It turns out the ones they have are Ver5.29 using Hynix MFR, so I grabbed a kit.
Heatspreader pulled, clearly Hynix MFR:
At first, the results were beyond disappointing. I couldn't get them to boot at anything higher than 2666, though they pulled that off with stock voltage:
DDR3-2666 11-13-13-35-2T@1.65v Super Pi 32M
I was somewhat pleased to find they could run DDR3-2400 Cas9 though it took considerable voltage.
DDR3-2400 9-11-11-28-1T@1.795v (=1.80v real) Super Pi 32M
