looks like they tested it with 6400

I looked at ASRock's workstation motherboard and I see this specified:

Max. DIMM Frequency     5600 MHz (1DPC); 3600 MHz (2DPC)]]> Sat, 10 May 2025 23:09:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=107890&PID=192651&title=x870e-taichi-fastest-ddr5-ecc-rampound#192651 https://forum.asrock.com/forum_posts.asp?TID=107890&PID=192649&title=x870e-taichi-fastest-ddr5-ecc-rampound#192649 Author: eccential

It depends on the processor you put into it.

Official AMD specs says...
7000-series supports upto 5200MT/s
8000G-series supports upto 5200MT/s(**)
9000-series supports upto 5600MT/s

** ECC only supported on PRO variants on monolithic APU dies.

In reality, I imagine 5600MT/s will work just fine on all of them.
I'm running two sticks of MTC20C2085S1EC56BR on my B850M-X (WiFi) with 9800X3D at stock speed (5600MT/s 46-45-45-90). No problems.

I went with Micron because Crucial used to sell them directly.
The other option was one of these:
https://www.kingston.com/en/memory/server-premier/ddr5-5600mts-ecc-unbuffered-dimm

I imagine 64GB ECC UDIMMs will be available at some point from these companies. I don't really need it, but it'd be cool to have 128GB with two sticks.

Just make sure to get UNBUFFERED DIMMs.

What is the fastest DDR5 ECC RAM memory supported?
Any issues with 5600 MT/s ?]]> Sat, 10 May 2025 08:43:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=107890&PID=192642&title=x870e-taichi-fastest-ddr5-ecc-rampound#192642
