I am having a similar issue. Thanks for the information. It seems I have been all over looking for a feasible solution. ]]> Sun, 08 Nov 2020 11:39:56 +0000 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=81236&title=asrock-b450-pro4-ram-stuck-at-2133mhz#81236 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73090&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73090 Author: diycuguja

I have Patriot Viper 4 PV416G320C6K (red, non-rgb Viper 4) and it runs 100% stable with XMP profile 3200Mhz CL16, even when AsRock's QVL list claims it runs stable only at 2933Mhz. Mine has Hynix C.

I have Asrock B450M Pro4 with 3.30 Bios and Ryzen 5 2600.

Try to use my timings (sorry for the bad photos, but hopefully you have everything in the same order). https://imgur.com/a/lvq3RG6

I doubt it will help though, sounds like your motherboard is bad, or something is wrong with the CPU's memory controller. ]]> Tue, 25 Feb 2020 00:11:32 +0000 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73090&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73090 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73018&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73018 Author: Ray62

Good morning.

It looks like the B channel has a tick, just running at lower frequency.

I would check the CPU and the socket for it (contacts) and the ram slots like ThreeDee posted.

A test of the CPU in another known good AM4 board and/or another known good CPU with your board would be helpfull.

A good repair shop should be able to do that for a small fee.

I use a windows tool to test slots and i dont found errors. Is there a way to test cpu? ]]> Sat, 22 Feb 2020 11:11:35 +0000 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73016&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73016 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73015&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73015 Author: ThreeDee

Yes, sticks works fine in A2 but if i add the second in B2 the bios reset and speed return to 2133mhz. Unfortunately i dont have another cpu. ]]> Sat, 22 Feb 2020 09:42:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73013&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73013 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73012&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73012 Author: ThreeDee

Nothing works. I tried another ram (lpx corsair 3000 mhz) and i have the same problem. I really dont know what to do. ]]> Sat, 22 Feb 2020 09:11:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=13695&PID=73009&title=asrock-b450-pro4-ram-stuck-at-2133mhz#73009
