Lenovo ThinkSystem 16GB 2Rx8 DDR4-2933 RDIMM TruDDR4 Performance+ Memory

Server memory has to match what the platform expects, and this module is specific about it. The Lenovo ThinkSystem 16GB 2Rx8 DDR4-2933 RDIMM, part number 4X77A12184, is a registered DIMM with ECC, running at 1.2V.

Capacity is 16GB per module. The 2Rx8 label describes a two-rank layout built from x8 chips, and 2933 is the transfer rate in MT/s. Registered modules suit servers that fill many slots, because the register reduces electrical load on the memory controller. ECC lets the module detect and correct single-bit errors, which is why servers use it.

The TruDDR4 Performance+ name is Lenovo's designation for this module line. Use it to add capacity to a ThinkSystem server or to replace a failed DIMM. Mixing module types in one server can cause problems, so match what is already installed.

Available in new, refurbished and used condition. New and refurbished carry 1 year or 3 years of warranty; used carries 90 days. Add the module to an RFQ with your quantity and ask for any of the three conditions.
