NEMIX RAM 96GB DDR5 5600 ECC RDIMM Kit

This 96GB kit contains two 48GB DDR5 5600 registered DIMMs with ECC and a CL46 latency. Modules run at 1.1V and use a 288-pin form factor with a 1Rx4 organisation. The kit is built for the Lenovo ThinkSystem SR655 V3 AI server.

Compatibility Check Before Ordering

Confirm that your SR655 V3 supports DDR5 5600 registered ECC memory and has two free 288-pin slots. Verify the system BIOS is current enough for 48GB 1Rx4 modules. Ensure the memory voltage setting matches the 1.1V specification.

Ideal For Memory Expansion In SR655 V3

Suits administrators adding 96GB of registered ECC capacity to a compatible Lenovo ThinkSystem SR655 V3. Not for systems that require unbuffered or non-ECC DDR5, for boards limited to lower densities per slot, or for any platform outside the validated SR655 V3 configuration.

Questions about this item

Does the kit include only the two 48 GB RDIMMs or are cables or brackets supplied as well?

The package contains the two 48 GB DDR5 5600 ECC RDIMM modules and nothing else; no cables, brackets or additional hardware are included.

Should I choose the 96 GB (2×48 GB) kit or would a single 48 GB module be better for the ThinkSystem SR655 V3?

The 96 GB kit provides two matched 1Rx4 modules for dual-channel operation, which the SR655 V3 memory controller is designed to use for maximum bandwidth.

What does the 5600 MHz rating mean once the memory is installed in the SR655 V3?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1 V, delivering the rated throughput and error-correction the server platform expects.
