NEMIX RAM 256GB (4×64GB) DDR5 5600 CL46 ECC RDIMM memory upgrade for Lenovo ThinkSystem SR780a V3

System-Specific DDR5 Kit

This 256GB kit contains four 64GB registered DDR5 modules built for the Lenovo ThinkSystem SR780a V3 rack server. It targets administrators who need to expand memory capacity in that exact platform without mixing module types.

Registered ECC with 4Rx4 Organisation

Each module runs at 5600 MT/s with a CAS latency of 46 at 1.1V and uses a 4Rx4 layout on 288-pin RDIMM form factor. The registered buffer and on-die ECC provide the signal integrity and error correction required by the qualified server motherboard.

Four-Module Population for Maximum Capacity

Populating four slots with this matched kit delivers the full 256GB in a balanced configuration, leaving remaining DIMM slots available for future expansion. The kit eliminates the need to source individual sticks and ensures identical rank structure and timing across all populated channels.
