128 GB DDR5 ECC Registered RDIMM

This 128 GB DDR5 5600 module is a single ECC registered DIMM built for Supermicro X13DEG and X13DEH series motherboards. It targets server and workstation operators who need maximum capacity per slot without mixing memory types.

Thermals noise and power

The module runs at 1.1 V with no heat spreader, relying on system airflow for cooling. Registered buffering and ECC add minimal latency overhead while maintaining signal integrity at CL46 under sustained server workloads.

What the JEDEC compliance changes

Full JEDEC and ROHS compliance means the DIMM meets OEM specifications for warranty-safe installation. The registered design prevents mixing with unbuffered or load-reduced modules, so all slots must use identical registered ECC parts.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in a Supermicro X13DEG motherboard, and what step is often missed?

Align the key notch with the slot, press straight down until both retention clips click, then verify the module is fully seated; the step often missed is confirming both clips have locked on a 128GB registered DIMM.

What maintenance or replacement will this 128GB ECC registered module need over its service life?

No routine maintenance is required; if a correctable error count rises or the module fails POST, replace the single 128GB stick — matched 4Rx4 modules should be swapped together to keep rank symmetry.

What limit appears first when this CL46 1.1V DDR5 RDIMM runs sustained workloads on a compatible server board?

The CAS latency of 46 at 5600 MT/s sets the timing ceiling; sustained throughput is bounded by the JEDEC-standard 5600 speed grade and the registered buffer's command/address delay.
