2) increase cpu vccio to 1.0875 (a few notches above 1.05V)
the audio dac is broke due to W10A, works fine on 1151, broke with 1607.
FYI, the audio issue I had wasn't related to W10A. I don't have W10A, just regular Win10 1511. The problem I ran into is definitely a bug in all of the drivers except the 7786 one shown on the R5-E10's page that is NOT available for download from the R5E page. I didn't change anything except the version of the driver and it all started working. I think that definitively demonstrates that it's not user error. I posted about it with @raja hoping he'd bring it to someone's attention and have the drivers tested/replaced with the only driver where all the features actually work. Basically 7829, 7571, 7450, 7373, 7324, and 7295 should all be pulled from the site and replaced with the 7786 driver.
I did try rated timings with 2T, but I've never tried the modes before. I hadn't looked into what they do. Can you elaborate what the different modes actually do?
VSA I have always run at 1.05v(with tests up to 1.2v, but it never helped), but I haven't tried higher vccio, or higher than 1.395v on vdimm. That's again a result of not having time to look into what the cpu and dimms can actually tolerate. My kit is the red corsair vengeance 3000mhz 15-17-17-35 4x8gb kit. I don't even know what IC's are on them. I'll give all this a shot when i have the time though.
