32GB DDR5 6400 ECC RDIMM kit

This 32GB dual-channel kit uses 288-pin DDR5 RDIMM modules rated at 6400 MT/s with CL32 32-39-39 timings at 1.40V. Registered design and on-die plus side-band ECC target server and workstation platforms that require registered memory with error correction.

Upgrade from slower or non-ECC DDR5

Replacing lower-speed DDR5 or unbuffered ECC modules adds the register clock driver and dual ECC layers needed for multi-DIMM stability in registered-memory slots. The jump is worth it when the platform demands registered DIMMs and the workload benefits from 6400 MT/s throughput.

32GB capacity for virtualization and databases

Two 16GB modules provide 32GB total, handling typical virtualization hosts, database buffers and compute nodes. Workloads needing more than 32GB per channel or higher densities will require larger-capacity RDIMMs or additional memory channels beyond this kit.

Questions about this item

Does this 288-pin DDR5 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR5 RDIMM form factor matches standard registered DIMM slots on compatible server motherboards.

What BIOS setting should I check after installing these 1.40V registered modules?

Verify the memory runs at DDR5 6400 with CL32 32-39-39 timings and that the registered clock driver is recognised by the platform.

When should I consider replacing these ECC registered sticks?

Replace them if the on-die ECC or side-band ECC logs uncorrectable errors, or if the temperature sensor reports sustained overheating.
