Here's a piece of software that does it for you:

http://www.overclock.net/forum/13-amd-general/1640919-ryzen-dram-calculator-1-0-0-beta-3-overclocking-dram-am4.html

Of course, should you choose to you it, you'll do it at your own risk. On my system the safe timings worked but seemed to make L3 cache benchmark (AIDA64) results more unstable than normally. Furthermore, not all benchmarks showed a positive result from tightening the timings and the latency change was insignificant, so in the end I went back to XMP timings (with CL16 dropped to CL14).

@PetrolHead
1USMUS is doing a rewrite of the software, should be out 7-10 days today.

I have just updated to 4.5 then 4.6
But one core CPU-0 is stuck @3.59Ghz FSB 90Mhz
And Memory @2.65Ghz should be 2933Mhz
I tried the 4.61 same thing.
HWInfo says all cores 3.975Mhz FSB 99.8Mhz as usual
But SIV64X says different, one core CPU-0 is stuck @3.59Ghz FSB 90Mhz
And Memory @2.65Ghz should be 2933Mhz
Benchmarks are low around the CPU 3.6Ghz and Mem 2.6Ghz level

Oh dear :(
How do i go back safely ? :)

My sig is not showing for me EDIT: now it does Embarrassed

I don't know if it was a coincidence or not since it does not seem like this bios update is targeted at the new 2000G processors, but my system got more stable and I was able to achieve higher frequencies with -again- much more stability than before. I'm using my 2200g @ 3925 with perfect stability, I could go even higher but it would require 1.4 V or more so I'd rather keep it at this.

think of it more like targeted to tweak and polish the bios update for the 2000 series

eg wifi fix etc

the first bios never gives the best results...........

Welcome Christoph

https://community.amd.com/community/gaming/blog/2017/05/25/community-update-4-lets-talk-dram

thanks and I've read that so many times but that does not help at all, the info is useless

does anyone have a guide about how to calculate timings manually?

In Taichi the system is very stable and with incredible responsiveness. This BIOS 4.40 is really very good, now, I only update if there is any improvement of the infinity fabric improving latencies and etc ...

Ok guys I have had time to roll back my bios to 3.00 and these new bios need some work.

I only have the aid64 trial installed so I can only see "read speed" buutttt...

P3.00
51700 read @ 3466 14-14-14-26

P4.7
41700 read @ 3466 14-14-14-26


Both had the same latency of 68 ns
By my math that's a 20% hit to memory bandwidth...not something I would see as "small"

*edit* maybe this is a stupid thought but I wonder since the newer bios are for the pinnacle ridge chips if it isnt just reserving that memory bandwidth for the onboard video even tho im not using that chip...if that makes sense.

Here I have the same problem with the transfer rates, I went back to using BIOS 4.40 which is really very good. What you talk about booking bandwidth for the IGPU for me makes a lot of sense ...

Ill have to compare your boards 4.4 and see what revision that would be for my ab350 and try it.

Tried v4.6 which was released a week before your 4.4 and no noticeable loss in bandwidth. I think its just the latest version, 4.7 , that does it.

Any news about this error? Someone found a solution or get answer from support? One answer was "Support say is AMD Bug not Asrock Bios fault". (in oc.net forum)
