  • 2 V operation reduces power draw per module
  • Validated compatibility with Supermicro H11SSL-NC motherboards

Server ECC RDIMM Upgrade

This 8GB DDR4 3200 registered DIMM adds ECC-protected capacity to a Supermicro H11SSL-NC motherboard running AMD EPYC processors. The module operates at 1.2V with CL22 latency and uses a single-rank 1Rx8 organisation for broad slot compatibility.

Replaces Slower or Smaller Modules

Upgrading from lower-speed DDR4 or non-ECC unbuffered memory is worthwhile when the workload demands error correction and registered signalling for multi-DIMM stability. The jump makes sense for virtualisation hosts, database nodes or NAS appliances that hit capacity limits on the existing configuration.

Tool-Free Slot Installation

The 288-pin RDIMM seats in the standard DDR4 slot without cables or brackets; align the notch, press evenly until the retention clips engage, then verify detection in BIOS. Common issues include mixing registered and unbuffered DIMMs in the same channel or exceeding the per-channel rank limit documented in the motherboard manual.

Questions about this item

Does the 288-pin RDIMM fit a Supermicro H11SSL-NC motherboard?

The 288-pin DDR4 RDIMM form factor matches the memory slots on the Supermicro H11SSL-NC AMD EPYC series motherboard.

What is the correct way to seat the 1Rx8 ECC registered module?

Align the notch with the slot key, press down firmly until both retention clips click, then verify the system registers 8 GB at 3200 MT/s with ECC active.

When should the module be replaced if ECC starts logging correctable errors?

Replace the stick once the platform firmware reports a rising correctable-error count that exceeds the vendor threshold, as the 1.20 V DDR4 chips cannot be serviced in place.
