I am looking for some 32GB RDIMM ECC RAMs for ASUS Pro WS X570-ACE motherboard to max out the RAM storage. But the official ASUS memory QVL of ECC memories do not include any 32GB memory modules. The best I can find on the list is Kingston 16GB ECC RAM (RDIMM).

Could you please suggest a high-density RAM module that will be compatible with the motherboard? I plan to install a Ryzen 5950x CPU on it. Thanks.

Are you sure registered ram is supported on this platform?

I thought ECC UDIMMS were required.

BTW, I do have ECC on my X570-ACE but it is unbuffered. 2X16GB ECC UDIMMs listed in my sig

Actually, I have no experience with this motherboard and I am not sure. But the official QVL list includes Kingston's RDIMM (see the attached file).

It appears the motherboard works with both UDIMM and RDIMM. Please correct me if I am wrong.

I looked up most of the dimms, even the ones that said were registered were udimms (out of the ones I checked). As far as I know x570 doesn't support registered dimm's. The amount of work in that screenshot points it out enough. I'd get some 32 gb samsung ecc udimm's.

Here's one more option: Crucial lists two on their web site if you punch in your board. Both are the no-heatsink variety. 3200 CL22 or 2666 CL19 32GB unbuffered ECC single sticks. Both run 1.2V and are out of stock on their website. I wonder how much you could clock them up if you added heatsinks and raised the voltage. Kingston doesn't list anything useful, only non-ECC stuff.

Out of stock forever. Crucial discontinued all their ECC products.

I've read some poeple having trouble with the 3200 version. 2666 is more secure.
