Capacity and Configuration

This kit delivers 512GB of DDR5 server memory arranged as eight 64GB modules. It is built for administrators who need maximum registered ECC capacity in a single qualified package for the Lenovo ThinkSystem SR680a V3.

Platform Limits

The DDR5 5600 standard sets the electrical and timing envelope at 1.10V with a CAS latency of 46 cycles. Registered DIMMs add a clock cycle of buffering, so the memory controller must support registered operation and the specific 2Rx4 organisation used here.

Deciding Specification

Compatibility is locked to the Lenovo ThinkSystem SR680a V3 rack server through part number MR44800-924K8; the modules will not function in desktop boards, consumer workstations or other server platforms that require unbuffered or differently ranked DDR5.

Questions about this item

Should I choose the 512GB kit with eight 64GB modules or a smaller capacity?

The kit provides 512GB total across eight 64GB RDIMMs, matching the Lenovo ThinkSystem SR680a V3 maximum supported configuration.

What does the 5600 speed mean once installed in the server?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, delivering the rated throughput when the platform enables the full data rate.

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

The 288-pin DDR5 RDIMM form factor with ECC and registered buffering is required by the ThinkSystem SR680a V3 memory slots; other form factors will not fit or function.
