Possible to have 256G RAM in supermicro X10SDV mother board?

I've found my homelab build with X10SDV-16C-TLN4F is now limited by its 128G RAM capacity.

Although the mother board spec says it supports up to 128GB registered ECC RDIMM with 2133/1866/1600MHz. I wonder if anyone successfully upgrade to 256GB (64x4)?

It is a pity supermicro doesn't provide comparable mini-ITX mother boards in its X11/X12/X13 generations

The D-1587 appears to be only supporting 128Gb so i believe you will find that is the limitation.

Yes probably.

I once had a lab build with NUC6i3SYK. Its CPU i3-6100U spec supports 32GB RAM at most. However, it works just fine with 64G (32x2). Don't know if Xeon D-1587 could be similar

If you have a 64GB dimm give it a try?
(32GB dimms were the largest ones when the xeon d cpus were released, not counting lrdimms)

been curios and grabbed four 64GB RDIMMs to stuff one of my X10SDV-8C boards: NO success. Even just DIMM A1 populated with 1 stick gives a "memory signal is too marginal" error.
*Might* work with LRDIMMs, but do not have 64GB LRDIMM for testing....

Would you please share your RAM brand and product code? I already tried with LRDIMM (SAMSUNG M386A8K40BM1 CPB), but no luck.

So probably it just won't work

I can confirm the same thing with SKhynix HMAA8GR7AJR4N. Even tried manually setting the memory speed from Auto to 1333.
