768GB DDR5 ECC RDIMM kit for Lenovo SR780a V3

This eight-module kit delivers 768GB of registered DDR5 memory built for the Lenovo ThinkSystem SR780a V3 rack server. Each 96GB module operates at 5600MHz with CL46 latency and 1.1V power draw. The 2Rx4 organisation and on-die ECC suit enterprise workloads that demand data integrity and high capacity per slot.

Sustained load behaviour with registered DDR5

Registered buffering reduces electrical load on the memory controller, allowing all eight slots to run at the rated 5600MHz without signal degradation during long compute runs. ECC corrects single-bit errors in real time, preventing silent data corruption during extended database or virtualisation tasks. The 1.1V operating voltage keeps power draw predictable under continuous utilisation.

Verify slot count and BIOS before ordering

Confirm the SR780a V3 chassis provides eight available 288-pin DDR5 RDIMM slots and that the system BIOS supports 96GB 2Rx4 modules at 5600MHz. Mixed-rank or mixed-capacity populations can reduce achievable speed, so plan a full-kit installation. Ensure the server firmware is current to initialise the full 768GB capacity correctly.

Questions sur cet article

How much power does the 768GB kit draw at its rated 1.1V?

Each 96GB module operates at 1.1V; total draw depends on how many of the eight DIMM slots the server populates and the platform's memory controller efficiency.

Does the Lenovo ThinkSystem SR780a V3 need a specific BIOS revision before these 2Rx4 RDIMMs are recognised?

The kit is validated for the SR780a V3; installing the latest Lenovo firmware ensures the 5600 MT/s speed and ECC functions are enabled at boot.

Can I mix these 5600 CL46 modules with slower DDR5 already installed in the server?

The memory controller will run all populated channels at the lowest common speed and latency, so older DDR5 will down-clock this kit to match.
