384GB DDR5 ECC RDIMM kit for Lenovo ST650 V3

This 384GB kit contains four 96GB DDR5 5600 registered DIMMs with ECC and a CL46 latency. It is built for the Lenovo ThinkSystem ST650 V3 tower server and targets administrators who need maximum registered memory capacity in that platform.

Verify DDR5 RDIMM slot count

Before ordering, confirm that your ST650 V3 has four available 288-pin DDR5 RDIMM slots and that the system BIOS and processor configuration support 384GB of registered ECC memory at 5600 MT/s. The modules operate at 1.1V and are organised as 2Rx4 rank.

Registered design with no heat spreader for dense

Each module uses a standard 288-pin registered DDR5 form factor without a heat spreader, allowing tight spacing in the ST650 V3 memory tray. The registered buffer reduces electrical load on the memory controller, and the ECC function corrects single-bit errors during continuous server workloads.
