Lenovo SR780a V3 memory kit

This 384 GB kit supplies four 96 GB DDR5 5600 registered DIMMs built for the Lenovo ThinkSystem SR780a V3 rack server. Each module carries ECC and a 2Rx4 organisation to protect data integrity in enterprise workloads. The kit arrives as a matched set of four modules.

DDR5 5600 registered limits

Registered DDR5 at 5600 MT/s requires a server platform that supports PC5-44800 speeds and ECC correction. The memory controller must accept 2Rx4 dual-rank modules operating at 1.1 V. Population rules and maximum capacity per channel are defined by the system firmware and cannot be exceeded.

Check server configuration before ordering

Verify that the SR780a V3 has enough free 288-pin DDR5 slots for all four modules and that the current BIOS revision supports 96 GB RDIMMs. Confirm the planned memory population order matches the vendor guidelines for this model. Ensure the operating system and applications can utilise the full 384 GB capacity.

Questions about this item

Should I pick the 4 x 96 GB kit or a different capacity for my SR780a V3?

The kit provides 384 GB total across four 96 GB modules, matching the SR780a V3 memory slots for maximum supported capacity.

What does the DDR5 5600 PC5-44800 rating mean for actual throughput in this server?

The modules run at 5600 MT/s with CL46 latency at 1.1 V, giving the SR780a V3 the highest standard DDR5 speed the platform supports.

How does the 288-pin ECC RDIMM interface affect compatibility and limits?

The 288-pin registered DIMM with 2Rx4 organisation and on-die ECC is the required form factor for the SR780a V3 memory controllers.
