You DO have Mem Training set to Disabled, right?

That is the ONLY thing that would at boot.

Well......... No remnants of Ryzen Master Utility hanging around?

Too, remember.

Every new AGESA release is a ground up rewrite regarding BIOSes.

New releases are not something I would consider mature enough to reliably OC on.

mem training has been auto and training stopped when I upped ProcODT from 60ohm to 68.8ohm , I'll try with it disabled but don't know if it will make any difference.

I've been playing a little with tightening the timings and here is my result. 3200 v1 was the initial set (safe), 3200 v2 is with tighter ones (fast).

Plus I have raised the ProcODT to 68.6 Ohm which helped with the stability or RAM. Also raised the Voltage of RAM from 1.35 to 1.36. SOC is on 1.1V.  MEMORY CLEAR (contrary to what the Ryzen DRAM Calculator recommends) is set to AUTO. I have left memory training untouched... with ProcODT 68.6 it boots superfast anyways.

3200 CL14 v1>


3200 CL14 v2>


3200 v2 timings:


To sum things up: FINALLY, a golden BIOS/UEFI for me! THANK YOU AMD and THANK YOU ASROCK.

Yes 68.8 ProcODT definitely helps with booting and stability with dual rank 16GB modules. And agreed new Agesa has helped greatly with stability with high speed ram @ 3200Mhz especially a 4 x 16GB config

Went back to P2.00 BIOS.  L1.91E added nothing for me, and made my RAM settings less stable.  Even the Safe settings stopped being stable.

MNMadman - sorry to hear...  E1.91 is a blessing for me... Running now 4x 16GB DR 3200 CL14 with super-tight timings, 1000000% stable (bought the software you recommended at the end lol... too much hassle with HCI ;-) ).
I thought about OCing it to 3400 CL16 maybe... but is it worth it? I already achieved ~97000 MB/s read write and copy in AIDA64.

Heard the best way to test memory stability is from a cold boot run memtest to 200% if no errors then shut down comp and do another cold boot (turn power off at the wall I assume) then rum mentest to 200% again, do this procedure 3 or 4 times and chuck in a few war reboots as well and if there is no errors in memtest then should be good.

Lots are saying with Ryzen that they can run memtest (HCI Mentest or Ramtest) to over 1000% without error but after a reboot or cold boot then memory testing will fail and give errors ....so worth a try.


@ Sonic.....good luck with 3400, I reckon it's a fat chance of getting that speed with DR 16GB sticks especially when using 64GB.....I can run 3333 with 4 x 16GB but it will always give an error with ramtest, usually before it hits 100% testing and I haven't been able to stabilize that speed yet.

Thanks lowdog, however I really ask myself if it would be worth the hassle... 
To be frank I was totally fed up with the results of my experiments (till E1.91 and the big success with 3200).... So this time I am asking myself if it would provide any real benefits compared to the current setup and throughput. 

3200 CL14 tight timings -- ca 97000 MB/s in read write and copy AIDA64 benchmark vs 3400 (probably) CL16 with looser timings?
I mean the infinite fabric would probably run faster but if it would be really noticeable? Anyone have experience in this area?
