384 GB DDR5 ECC RDIMM kit

This 384 GB kit contains four 96 GB DDR5 5600 registered DIMMs with ECC and a CL46 latency. It operates at 1.10 V and uses a 288-pin 2Rx4 layout built with major OEM chips. The modules are validated for the Lenovo ThinkSystem SR680a V3 rack server.

Suited for SR680a V3 capacity upgrades

IT teams expanding memory in a Lenovo ThinkSystem SR680a V3 will match the platform’s registered ECC requirement exactly. Builders needing unbuffered UDIMMs, non-ECC modules, lower capacities or different form factors should look at other product lines.

Fills four DDR5 RDIMM slots

Each 96 GB module occupies one 288-pin registered slot, so the kit consumes four sockets and delivers 384 GB of error-correcting memory. The 1.10 V operation keeps power draw within standard DDR5 limits, leaving remaining slots free for future expansion if the chassis supports more.

Questions about this item

What motherboard slot type is required to install these 288-pin DDR5 RDIMM modules?

The modules require a motherboard with 288-pin DDR5 RDIMM slots; the Lenovo ThinkSystem SR680a V3 provides the correct socket and registered memory support.

Will the 2Rx4 rank organisation work with other DDR5 RDIMMs already installed in the server?

The 2Rx4 dual-rank layout is compatible with the SR680a V3 memory architecture; populate remaining channels following the server's population rules for matched rank counts per channel.

How can I confirm the kit is running at 5600 MT/s with CL46 timings after installation?

Check the system BIOS or UEFI memory information screen; it should report DDR5 5600 (PC5-44800) speed and CAS latency 46 for each of the four 96 GB modules.
