I don't understand it. I have my timings at 3-4-4-8 and in memtest I get 3 errors on test 3 on auto settings for speed which runs it at 306.6Mhz. When I put it at 320Mhz it'll get a few more errors. at 400 Mhz i'll get 27 errors. I set everything back to default and ran it at 400Mhz with 2-2-3-2 timings as it's what it's supposed to do. It got 3 errors. Back when I was running my 1.8A my ram test flawlessly on 2-2-2-2 timings and it ran at 233Mhz. I know these are CH-5 chips and they don't overclock great but why the heck can't it even do 320Mhz? The max voltage on my mobo for the ram is 2.85 and even with that it got errors.
