128 GB DDR4 ECC RDIMM for Supermicro

This 128 GB registered DDR4 module targets administrators upgrading Supermicro servers and workstations that require ECC protection. It delivers a single high-density stick so populated DIMM slots remain available for future expansion.

3200 MT/s CL22 with 4Rx4 organisation

Rated at DDR4 3200 (PC4-25600) and CAS latency 22, the module handles virtualisation hosts, database buffers and large dataset caching. The quad-rank x4 layout maximises capacity per slot but limits maximum memory frequency on some platforms when multiple ranks are populated.

1.2 V 288-pin registered design

The 1.20 V RDIMM fits standard DDR4 server boards without extra cooling because it has no heat spreader. Registered signalling reduces electrical load on the memory controller, freeing headroom for additional modules while the ECC function corrects single-bit errors in flight.

Questions about this item

Will this 128GB DDR4 3200 4Rx4 ECC RDIMM run alongside my existing lower-capacity RDIMMs in the same Supermicro server?

Mixing ranks and capacities is possible if the motherboard supports it, but the 4Rx4 organisation and 128GB density may limit which slots can be populated together. Check the Supermicro memory population guide for your specific chassis.

How can I verify the module is running at 3200MT/s with CL22 after installation?

Enter the BIOS or use a tool like dmidecode on Linux; the SPD data will show PC4-25600, 3200MT/s, CAS 22, 1.20V and ECC registered status.

Does the package include a heat spreader or any mounting hardware, or must I buy those separately?

The module ships without a heat spreader and no extra brackets are included; it installs directly into a standard 288-pin DDR4 RDIMM slot.
