384GB DDR5 5600 ECC RDIMM kit

This 384GB kit contains six 64GB DDR5 5600 registered DIMMs built for the Lenovo ThinkEdge SE455i V3 inferencing server. Each module runs at 1.1V with CL46 latency and a 2Rx4 organisation. ECC and registered buffering protect data integrity in sustained workloads.

Suits inferencing servers needing maximum capacity

The 384GB total fits the ThinkEdge SE455i V3 when every slot is filled with 64GB RDIMMs. Buyers who need non-ECC memory, unbuffered DIMMs or a lower total capacity should look at a different kit. Systems that do not support registered ECC DDR5 cannot use these modules.

Registered ECC DDR5 with 2Rx4 organisation

The 2Rx4 rank structure and registered ECC design are the single specification that decides compatibility with the ThinkEdge SE455i V3 memory controller. Verify that the platform requires registered ECC DDR5 RDIMMs before ordering.

Questions about this item

What server is required to use this 384GB DDR5 5600 ECC RDIMM kit?

This kit is validated for the Lenovo ThinkEdge SE455i V3 inferencing server; the motherboard must provide 288-pin DDR5 RDIMM slots that support 1.10 V registered memory.

Can I keep my existing DDR5 RDIMMs and add this 6 x 64GB kit?

Mixing is possible only if the installed modules are also DDR5 5600 registered ECC 2Rx4 parts running at 1.10 V; otherwise the system will default to the slowest common speed or may not post.

How do I confirm the 384GB kit is running at 5600 MT/s with ECC active?

Enter the server BIOS or UEFI and verify the memory speed reads 5600 MT/s (PC5-44800), total capacity shows 384 GB across six slots, and ECC status is reported as enabled.
