One slot's worth of headroom. That's what this is — a 16GB ECC UDIMM-A that slots into your Lenovo ThinkSystem and gives you the breathing room to stop paging to disk during that Monday-morning report run.
It's a 1Rx8 single-rank module at 5600MHz with ECC error correction, so the data integrity your server relies on stays intact. The UDIMM-A designation means it's the variant your specific ThinkSystem model calls for — not a generic swap that might post but won't validate.
Five units in stock right now. If your build list has this part number, you don't need to wait on a back-order cycle
