AGESA 1002a

   Yes as have, the problem seems to lie in the AGESA code, the change from 1.0.0.0a to 1.0.0.1a seems to have affected some memory kits more than other, I have Hynx chips in my Corsair, it seems, Samsung B dies are affected, I only lost 3-4GB/s, should wait on see if the new 1.0.0.2a will fix the problems, do you have the possibility to test with another memory kit?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

	A other User from overclock.net has done some Benchsmark. Now with Ryzen 2700X. It looks like the Drop happens only if CPU will be overclocked. http://www.overclock.net/forum/27231929-post3486.html 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?

	Here is a screenshot of my Corsair @ 3200MHz with Ryzen Timings calculator all else left to default after a UEFI reset, maybe it helps you, maybe you can ask on the Overclock.net forum for someone with a 1xxx Ryzen or even 2xxx and an Asus or MSI X370 to test this. 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 Edited by cristy6100 - 24 Apr 2018 at 3:18am

	Look again at my newest post on overclock.net. I did some more test. Just dont touch CPU Mutliper in Bios. Change it after in AMD MAster Tool. -> Full Memory Bandwidth. 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 checked and replied in the other thread :) 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: http://forum.asrock.com/forum_posts.asp?TID=8075&KW=&title=fatality-x370-itx-ac-bios-l451-very-buggy and here: http://forum.asrock.com/forum_posts.asp?TID=8166&KW=&title=yet-another-uefi-bug-with-ab350-x370-itx-ac here also: http://forum.asrock.com/forum_posts.asp?TID=8184&KW=&title=warning-to-users-with-older-video-cards And lastly: http://forum.asrock.com/forum_posts.asp?TID=8254&KW=&title=loud-pop-from-left-channel-when-poweron-reboot Maybe you can replicate some of them with your 2200G and B350 Pro4?
