Saying nothing about what the schedule is though. :| lol.

To get the thread back on track, where were we? :))

Oh yes, the dreaded problems with the 2200/2400G

You can read about the bugs I found here:

Maybe you can replicate some of them with your 2200G and B350 Pro4?

I hop Asrock fix that. i mean, with L4_61 you wont get better oc result as witrh P4_40, so the Timmings losing doesnt help. and you could see on my screenshot, Asrock doenst change a Ram Timming wiches you could see in Ryzen Timing Checker.

At last, Asrock are you hear and someone can check with Tech. or should i open a case, for all each other Boards aso?

I expect this behaviour to be fixed in 1.0.0.2a but not take my word for it, maybe it has something to do with ASRock in particular when OC'ing it loads some relaxed timings to improve stability at the cost of brute performance from the memory controller. It might be or it might not

Thats one again, sound not like a AGESA Problem. Other Boards hasnt this error so what i could see. So that a Bug from Asrock. And dont say, OC isnt supported. Thats just a joke on a Baord like the Taichi. And we dont had to talk about Samsung B-Die, we know that the works on all other Boards. Maybe someone has contact with Asrock and could check if the work on it?

The main AGESA and SMU code is shared among all AM4 boards, so only minor differences should be present in Taichi as opposed to Fatal1ty UEFI's.

Your best bet for the moment is to wait for the new UEFI's, and if the issues will not be fixed with 1.0.0.2a I don't think they ever will unfortunately, I would stay with 4.40 for the moment and you should send ASRock a message with the memory P/N and report the issue.

But you should wait until the new UEFI arrive, not that much waiting, I am also waiting for them because of other bugs in 1.0.0.1a, its been a long one month of waiting

Cheers

Your test arent with Ryzen 1xxx and not with the taichi. Are you shure, that your mainboard, the x370 ITX has the same issue with the Ryen 1xxxx? The "save" CBS settings in Profile should aso one error whiches was on all Asrock, but now should fixes, but on taichi it isnt (JZ did test the other Mainbaords, mybe you know him).

And by honest, iam arround 42000 with 3466-16 and you are around 49000 with 3333-16. i would clame about loss 2 or 3 % but i do loss more as 25% with the new bios. 

Look at this result. for me it look like a asrock "bug" or and amd bug and all other vendor has found a workaround:

Asus and Biostar already released UEFI's with 1.0.0.2a, Gigabyte and MSI I thing have betas already available, ASRock is the last one without 1.0.0.2a so it should come, usually ASRock is the fastest in releasing UEFI's but X370 UEFI development was slowed down by X470 boards, if you check the FTP server you will see they released about 10-15 UEFI's for X470 boards in the last 2 weeks, X370 comes next
