SuperMicro Compatible DDR5 RDIMM

This 128GB DDR5 5600 ECC registered module is built for SuperMicro X13SEI-F and X13SEI-TF motherboards. It delivers 44800 MT/s bandwidth with CL46 latency at 1.10V. The 4Rx4 Samsung, Micron or Hynix chips provide error-correcting stability for server workloads.

Suits single-slot capacity needs.

Install one 128GB stick to maximise density in a single 288-pin slot. Builders populating multiple channels should verify platform rank limits per channel. Systems requiring unbuffered UDIMMs or lower-density modules cannot use this registered 4Rx4 part.

4Rx4 rank determines channel population limits

The quad-rank x4 organisation counts as four logical ranks on the memory bus. SuperMicro X13 platforms typically allow eight ranks per channel, so two such modules fill one channel. Exceeding the rank limit prevents boot or forces speed reduction.

Questions about this item

Does this 128GB DDR5 5600 ECC RDIMM require a motherboard that supports registered memory?

Yes, this is a registered RDIMM with ECC, so the motherboard must support registered DDR5 memory and ECC functionality for it to operate correctly.

Can this 288-pin DDR5 module be installed alongside existing DDR5 modules of different speeds or capacities?

It can be installed alongside other DDR5 modules, but the system will run all memory at the speed of the slowest module and may require matching rank configurations for optimal stability.

How can I verify this 128GB DDR5 5600 CL46 module is running at its rated speed after installation?

Check the BIOS or UEFI memory information screen to confirm the module is detected at 5600 MT/s with CL46 timings and 1.10V voltage.
