Hey, thanks for posting and surprised it's not running.I have two KSM48E40BD8KM-32HM and the Asus WS W680 here.
and a Core i7 13700K
And it isn't running.
If I put only one DIMM into the Socket it is booting but with ridiculous fast RAM timings(normal for fast DDR5-RAM but too fast for DDR5-ECC).
One DIMM is even memtest stable.
But if you are putting 1 DIMM per channel into the system it isn't even booting.
I updated to the newest firmware and it isn't helping.
I think I am going to send it back.
I have a X13SAE+13700K+Kingston-ECC running with conservative RAM settings. Everything is running rock stable with 1DPC.
Currently with the Asus Board I try to set the RAM settings CL tRCD .... manually but so far no luck.
This is my X13SAE config
You indicated that you updated to the latest BIOS - did you confirm whether or not the Management Engine (ME) version of the board is at the level indicated by ASUS? I haven't updated the BIOS as I haven't had a chance to check the ME version.
I have a feeling the memory isn't compatible, however, there isn't any indication that I have that would suggest by looking at the Spec sheet that it shouldn't work.
Have you tried loading Optimized defaults and have confirmed that the RAM modules are fully seated? when I first stuck memory into this board, I was surprised by how much more force I had to push down the module to get it to really engage in comparison to my earlier DDR4 ECC RDIMM insertion experience, so wonder if something else is off?
Any thing resting on the board that is metal, or any screws that fell out and landed on something? just curious if going back to just CPU + RAM and then booting MemTest gives you a result? can you grab a screenshot from MemTest? I am just curious to see if the board "sees" the RAM correctly or not?
