Capacity and form factor

This kit provides 128GB of DDR5 memory across two 64GB registered DIMMs. Each module uses a 288-pin interface and a 2Rx4 organisation with ECC for error correction. The memory operates at 1.10V and carries a CAS latency of CL46.

Target platform and exclusions

The kit is validated for the Lenovo ThinkSystem SR780a V3 rack server and will not function in consumer desktop boards or laptops that require unbuffered non-ECC modules. Systems lacking DDR5 RDIMM support or those limited to lower maximum capacities per slot should look elsewhere.

Sustained operation

Registered buffering and on-die ECC maintain data integrity during continuous server workloads such as virtualisation and database processing. The 1.1V operating voltage helps limit thermal output when all slots are populated under prolonged load.

Questions sur cet article

Does this kit require a Lenovo ThinkSystem SR780a V3 server to operate?

Yes, the 128GB kit is built for the Lenovo ThinkSystem SR780a V3 and uses 288-pin DDR5 RDIMM modules that only fit that platform.

Can I keep older DDR5 RDIMMs installed while adding this 2x64GB kit?

The server must support mixed-capacity registered ECC modules at 5600 speed; check the system manual for approved population rules before mixing ranks.

How do I verify the memory runs at 5600 MT/s with CL46 after installation?

Enter the BIOS or use a tool like ipmitool to confirm the memory reports PC5-44800, 1.10V, and CL46 timings on each 64GB module.
