Probably should send him a PM.

Samsung memory seems to provide the highest stability and performance, headache free operation.
Sometimes Auto is ideal, auto timings... Compare to your modules timings but also compare with Auto timings... Auto is actually the fastest as long as the clock/ memory multi is just right.
For increasing the overclocked stability further is to turn up the voltages except the memory and the southbridge a couple ticks... This helps a lot.
The one picky thing about the ram is even know it passes a stress test or passes 5 hours of MemTest86, it could easily still be unstable for applications. That's when I found that Kingston was the issue. With Samsung everything works great. As far as I know Corsair are possibly the only manufacturer using Samsung modules, correct me if I'm wrong.
This may or may not be correct:
If Auto is faster it can be because timings were set incorrectly. If RAM timings are set incorrectly the board can revert to default spec for that timing, rather than whatever auto might provide when RAM timings are being determined at boot. I don't remember which timing it is, but people often suggest setting it lower than the math indicates for the minimum timing. The board will boot but the timing will be changed by the board to make things stable. Or, it might loosen some other timing to compensate.
