If the memory stick works (you can try them one by one), two should work in dual/quad channel.

If it doesn't, I would suspect the motherboard or CPU.]]> Thu, 13 Mar 2025 17:53:26 +0000 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=185550&title=650m-pro-rs-only-recognize-1-ddr5-ram#185550 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=185540&title=650m-pro-rs-only-recognize-1-ddr5-ram#185540 Author: albertkao

I updated bios to latest version 3.20.
Only one DDR5 RAM is recognized at the A2 slot.
The other DDR5 RAM is not recognized at the B2 slot.
It prevents the POST screen from appearing, i.e. only a blank screen appear, at the A1 or B1 slot.
I ordered a new DDR5 RAM.
I installed linux successfully on the SSD.
USB, Ethernet works as expected.
Thanks for your help!]]> Thu, 13 Mar 2025 08:05:23 +0000 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=185540&title=650m-pro-rs-only-recognize-1-ddr5-ram#185540 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=184678&title=650m-pro-rs-only-recognize-1-ddr5-ram#184678 Author: M440

The POST screen appeared 10-15 seconds after the computer is turned on.
Then it stayed the same (was unchanged) after a long time (more than 30 minutes).
Is there a way to change the "RAM training" time?]]> Mon, 10 Mar 2025 01:10:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=184491&title=650m-pro-rs-only-recognize-1-ddr5-ram#184491 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=184452&title=650m-pro-rs-only-recognize-1-ddr5-ram#184452 Author: albertkao

ASRock B650M Pro RS and 8500G only recognize 1 DDR5 RAM.

My CPU is AMD Ryzen 5 8500G.
My ASRock B650M Pro RS motherboard BIOS is 3.10.

I put the TeamGroup T-FORCE VULCAN Z DDR5 RAM 32GB (2x16GB) 5200MHz at the DIMM slots:
A2
B2

I have only one TEAMGROUP MP44L 1 TB M.2-2280 PCIe 4.0 X4 NVME SSD.
I put it at the gen 5 SSD socket (M2_1) but it prevents the POST screen from appearing, i.e. only a blank screen appear, so I remove it for now.
Then I get the POST screen.

However, ASRock B650M Pro RS and 8500G only recognize one DDR5 RAM at the A2 slot but its speed is at 4800Mhz, not 5200MHz.
The other three slots are "Not Present".
What do I do now?
Do I remove and reinsert the DDR5 RAM at the B2 slot until it is recognized during POST?
Do I put the gen 4 SSD on a gen 5 SSD socket (M2_1) only after both DDR5 RAMs are recognized during POST ?]]> Sun, 09 Mar 2025 10:13:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=100136&PID=184452&title=650m-pro-rs-only-recognize-1-ddr5-ram#184452
