Memory support is all over the place at the moment across all vendors. Did you TridentZ post at least? Just couldn't reach the full 2933 + CL14?
Yes, the TridentZ posted at 2133 (I think not even CL14), but 2933 was a no go (reboot to cleared CMOS). Even with looser timings (though obviously didn't go through the full menu of possibilities there).
I'm wondering if the CPU would respond well to a bit of extra voltage because the memory controller on this revision of the CPU is a bit of not-all-there. My understanding is that most people OC their CPU first, and I'm starting to wonder how much of the memory support issues is really CPU related....
FWIW, the Corsair won't post at CL14, as they must have for the above-linked review. Tighter doesn't help (at least, not that tight). I also tried 16-16-16-34 instead of 16-18-18-36 (iirc) and that posts, but still black-screens. It runs fine under cpu-z, chrome, and any other app that doesn't hit memory a lot, but an NLE that's running full-out is death to it. The extra volts on the RAM seems to keep it stable for nearly 10 seconds, instead of 2-3, but that's not much of an increase (and could just be random).
