I see. Didn't know that. I'll have to experiment with that tomorrow. I have to have it on for anything above 2400 usually. Probably because it's the Hynix memory and it's really picky about timings. I can push CL 12 on 2800, but not 2666, it's just very odd. Never know what numbers it's going to like. I'll mess with some odd timings and see what happens, maybe even stumble onto something that'll let me run higher than 2933.

I could bump up voltage to 1.4, soc 1.1-1.2 but not interested in doing that. If asus just supported my ram like they do with strix b350, strix x370 i wouldn't even need to push ram above rated volts to get stable 3200. Unless of course my cpu imc is preventing 3200mhz.
I'm also using 0810 since it includes extra features. And i'm not convinced 1001 bios will get me 3200mhz.
I'm not convinced 1001 is going to do anything for me either. Yeah, if you aren't comfortable with the voltages, then it's not worth it. I'm not sure why your board doesn't like that RAM.
Other things you can try, because sometimes training the RAM on Ryzen is finicky, is to try the safe 3200 timings, reboot into BIOS then try the normal timings. Sometimes Ryzen likes to creep up to the settings you are going for before it'll POST and work properly. I've had to do 2800 timings, then go to 2933 after. Even then it'll POST straight away, then memtest and you restart, then you get 3 beeps even after it passed memtest!
It could also be the chips IMC. Just never know. It's all a giant jigsaw puzzle linked together. Weak CPU cores, bad OC's. Weak SOC, may not give you high OC's on CPU and RAM. Weak IMC, can't get rated RAM speeds to run correctly.
I think even on auto this board will try for 1.1 SOC voltage when I did a 2933 clock on the RAM, so it might take 1.1 SOC voltage to get you 100% stable. The SoC is safe up to 1.25v from what I've read, but don't quote me on that. I'd double check first before going anywhere near that close if you decided to see what it actually takes to get 100% stability.Edited by Acidstorm - 11/10/17 at 10:14pm
