Hi, i bought the ASRock Z790 PG Sonic at 2024-05-18 and stumble into the same issue. I have bought a 64 GB Kit consisting of 2x32GB from Corsair. It is Corsair DIMM 64 GB DDR5-4800 (2x 32 GB) Dual-Kit (CMK64GX5M2A4800C40). In the recommended combination A2-B2 it does not work. The A1 and A2 slot do not work in any combination.

I tried every combination.

A1     A2     B1     B2     works?     combi
X     o     o     o     No     A1
o     X     o     o     No     A2
o     o     X     o     No     B1
o     o     o     X     Yes     B2
X     X     o     o     No     A1-A2
X     o     X     o     No     A1-B1
X     o     o     X     No     A1-B2
o     X     X     o     No     A2-B1
o     X     o     X     No     A2-B2
o     o     X     X     Yes     B1-B2

The modules are sold as DDR5-4800. In the BIOS they show up with 3600.
It is difficult to determine are Corsair not supported or the mainboard or the ram are defect.
At this link https://pg.asrock.com/mb/Intel/Z790%20PG%20Sonic/Specification.asp#MemoryRPL the Corsair modules are not mentioned. May this is the cause?

It's very hard to judge if I'm doing something wrong, there is no documentation about the BIOS (or UEFI) This is ridiculous.

I have also have the same memory and it works just not at rated speeds, but it works with two modules and it doesn't matter what two modules I use.

It is. Even limited to a matching pair for a total of 32gb, it won't boot.

Anyway I've never seen a package of 4 together, it's always 2s.]]> Mon, 20 Mar 2023 05:41:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104128&title=asrock-z790-pg-sonic-memory-issue#104128 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104081&title=asrock-z790-pg-sonic-memory-issue#104081 Author: RLGL

I'm having the same issue with the memory, it?™s all over the place and I'm currently running at 3600MHz trying to get 6000MHz XMP setting or 5400MHz with four sticks of Kingston 8GB 6000MHz modules]]> Tue, 14 Mar 2023 18:01:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104007&title=asrock-z790-pg-sonic-memory-issue#104007 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104004&title=asrock-z790-pg-sonic-memory-issue#104004 Author: JCLentine

Update, testing again, I was getting a stick now showing as 3600. Then checking each stick after that, getting 5600 on every one of them.

It may be the CPU is bad, but I've never seen anything like this happen where the memory speed appeared different every time.]]> Tue, 14 Mar 2023 03:21:08 +0000 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104004&title=asrock-z790-pg-sonic-memory-issue#104004 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104003&title=asrock-z790-pg-sonic-memory-issue#104003 Author: JCLentine

I did find that one of the four sticks was PC-4800 and the others were PC-5600 but that should have just slowed the others down to 4800 instead of not booting at all. So even in a single package they weren't identical.

I haven't seen any memory offered as such anywhere, I've literally only seen memory sold in 2's. If I could have bought 4 in 1, I would have.

Also how am I supposed to test them with a freeware program when I cannot boot the computer to install an OS yet?]]> Tue, 14 Mar 2023 01:56:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=25592&PID=104003&title=asrock-z790-pg-sonic-memory-issue#104003
