To get 3466 @ 14-14-15-14-28-42 stable, ended up having to play with AddrCmdSetup, CsOdtSetup, and CkeSetup. The calculator suggested either all three at 0 or 60 which rig did not like. It was a "what have I got to loose" kind of effort that stumbled upon what ended up making the whole thing work. Try those three settings at 1. Even with the 3800X currently using, it made the more aggressive timings work. Voltage was an iffy thing. Too little or too much resulted in errors. My setup liked only two ram voltages really, 1.3800 and 1.4100. Hope this helps.
