Ryzen 3000 series support

The LEDs come on after pushing power button, but cpu fan doesn't spin and it just appears to reset itself continuously. Switching back to a 1700X works fine. Has anyone got any XT processors running on an x370 based board (taichi specifically) ??

Some of us 3000 series X users experience your problem, example and solution in http://forum.asrock.com/forum_posts.asp?TID=14013 post no.4

x370 Taichi is notorious with 3000 series, hahahaah. you've got to find ways to tame it..

6.32 was the first version to add XT support it might worth trying rather than 6.40.

Hello there, 2 month ago i bought asrock b550m steel legende mb + ryzen 5 3600. Until yesterday i had no any problem when i get to update bios. After updating bios from 1.00 to v1.2 cpu always using turbo boost on balanced mode, before it was idle like 1.5-1.8ghz maybe even even less i dont remember correctly. Now all the time it is 3.7-4.11ghz in idle no any activities 1% cpu usage. Because i get info cpu temp goes high 50+ and fan makes noise. When i use power save mode i get 2.19 clocked cpu and not down or up. Any help would be appreciated.

Will Asrock be adding support for the Ryzen 5000 CPU's to x470 and B450 BIOS? I just saw MSI announce today that they will be supporting all of their X470 and B450 boards. I would not be pleased if Asrock doesn't follow MSI's lead in supporting the new CPUs. Personally I don't see any huge value in the hardware support of the X570 and B550 over the predecessors from a performance perspective in my particular situation (work software dev't + moderate gaming).

I'm using it on the x470 Master SLI/ac (that's nearly identical) with 3950x and it seems fine but some memory options are missing so if you tweak your RAM some options might not be available. I'd stick to P3.70 with "Update AMD AGESA Combo-AM4 1.0.0.4 Patch B" if you need those memory OC options with the Zen2 CPU. With P4.20 you can flashback to P3.70 if needed. The UEFI/BIOS is much better in P3.70. If you do up your BIOS version install the updated chipset drivers from AMD first before you flash and make sure your running at least Windows 10 ver1909.

I had a lengthy newegg review with instructions how I updated hassle free but it is not listed anymore. I copied my instructions below and updated them from when I was running a 3800x. The 3800x did just fine with air cooling so 3700x should be no problem but for 3950x you really should get the EK monoblock or heat can be a problem with the VRM's.

Upgrading to AMD Ryzen 7 3800X 8-Core (16 thread) 3.9 GHz (4.5 GHz Max Boost)
- Before swapping CPU:
- Reset to BIOS defaults, save, reboot
- If you have a BIOS/UEFI older than P1.90 update to P1.90 first!
- Be sure to update to BIOS/UEFI version P3.70 (minimum).
- Install new AMD chipset drivers and update Ryzen Master
- Swap CPU
- After swapping CPU:
- It is normal to have to wait some time for the motherboard to detect the new processor and readjust before posting. (potentially multiple reboots)
- Reset to BIOS to defaults again, save, reboot
- Do not use any pre-saved BIOS/UEFI profiles with your older processor. Save over top any existing profiles you had to avoid loading any incompatible settings you had with your prior processor.
- Do not panic when you see the voltages after your new 3000 series CPU is installed. Google "the_final_word_on_idle_voltages_for_3rd_gen_ryzen" and read the article there to understand what is happening. It is normal and related to core boosting behavior.

Hope this helps. I think the master is EOL now, I'd start grabbing a copy of the BIOS from the site in case the page is taken down. The Master SLI/ac page is no longer available.
