C6H Pre UEFI 1403

Juvir
Level 7
So I have a C6H, Ryzen 1800x, and 32GB of Corsair Dominator 3200 DDR4. (CMD16GX4M2B3200C16)

Prior to UEFI 1403, I could get my ram to run @3200 with the DOCP 4 profile, bus at 120, set to 3199, processor overclocked to 4020 with a multi of 33.5. Any other profile and i'd run into issues of some sort, but at least I had one that worked, right? Then I see UEFI 1403 come out, with more compatibility for more 3200+ speed ram. Awesome, maybe this will help!

Now, with UEFI 1403 and the new beta 1501, I cannot get my ram past 3066 no matter what profile or combination of settings I try. Anything higher than this and it will fail to post the first time, then default to a lower value before posting after the error. I've increased the boot voltage to 1.35 (which I didn't need in the earlier revisions) just to verify it wasn't a voltage issue. Verified the timings are set correctly (16-18-18-36) and still cannot get it to boot correctly. Is there something in the new revision i'm missing?

Do you get F9 code?

Edit: This is my settings. Still have cold boot bug but it works. url: http://imgur.com/a/5wjal

I'll have to double check, but i'm pretty sure it's the F9 code. I'm just so used to the same thing cropping up when I play with the ram speed I may just be taking it for granted. I also don't think we have the same ram sticks, as your timings are different. Also, why would you put your boot voltage up to 1.4v on 1.35v sticks? I've tried using DOCP profiles as well as manual settings with 1403 and 1501 and still cannot get it to post at 3200 for my ram. I may have to downgrade back to the 1200 series bios until this gets resolved.

Actually we have different kits (I have a Corsair kit too) but chips should be the same (my kit have Samsung B-Die). My kit is made for 16-18-18-36 like your but if you leave auto settings they works at 16-16-16-39 without issues.

I use 1.4V for boot just to be sure it boot @ 3200MHz.
