Maybe that's true. Still one issue for me may *I repeat MAY* be that the 1600MHz chips I had been running are unstable. The board certainly will not run them clocked at 1600, that much I pointed out.
I'm not sure how long running MemTest86 is required. Probably an overnight repeated test would prove/disprove something. But even if it passed, can the chips be suspect? Other chat boards seem to think that the MemTest would catch a problem, it is the best test to use. Others may disagree. When I was doing desktop support in my last job I could run MemTest, and 99% of the time it would show massive errors right away on test #1. On a few instances it would show errors once it got to test #6.
I know that when I did run MemTest on the 1600 chips it completed all tests with no errors. I don't know everything about RAM as far as if an unstable product would pass tests, but fail intermittently in use....?
I'd also like to see better quality control all around. I started this new box with ASUS mobos, but ran into bad board after bad board (memory slots bad, on-board audio failed, that sort of thing). I sold the 6th returned RMA ASUS board for $20 to get it out of here, having bought the Gigabyte (some friends had recommended them). I just had to swap this board due to a flaky PCIe x16 slot (I have another thread on this subject). The RMA board arrived last Monday, and so far has been stable. The Corsair Vengeance 1333 DDR3 has been running nonstop now for approx 8 hours without a hiccup. Definitive test? I hardly think so; I'd say if it runs flawlessly for 4-6 weeks I'd be more confident.
I'd rather get onto other things than constantly ripping open the box and re-working it (oh, and OT...the rear fan on the new case, an Aero Cool box, failed within 2 months....began making a ton of noise. Not a huge deal, I replaced it with a higher quality and quieter fan, but still...I may be naive, but I like to think companies can actually sell a quality product).
