Not every ThinkSystem slot takes an RDIMM. If your chassis spec calls for a UDIMM, you need the right module — not a guess that doesn't post.
This is a 16GB TruDDR5 ECC UDIMM at 4800MHz in a 1Rx8 configuration. It's built for ThinkSystem platforms that use unbuffered DIMM slots, and the ECC layer catches bit-flips before they become a 2am page.
We've got 12 on hand. If your server manual says UDIMM, this is the one that goes in without a fight.
