64GB DDR4 ECC RDIMM for Supermicro H11SSL-NC

This 64GB DDR4 3200 registered DIMM is built for the Supermicro H11SSL-NC motherboard and AMD EPYC platforms. It targets server and workstation administrators who need validated ECC memory for mission-critical workloads. The module uses major OEM chips from Samsung, Micron or Hynix and runs at 1.20V.

Sustained load stability with CL22 registered timing

The module operates at DDR4 3200 PC4-25600 with a CL22 latency and 2Rx4 organisation. Registered buffering reduces electrical load on the memory controller during continuous operation. All units are stress-tested under load before shipment to verify reliability in 24/7 environments. ECC detection corrects single-bit errors without interrupting service.

Simple DIMM installation with manual guidance

The 288-pin RDIMM installs in standard DDR4 slots on the H11SSL-NC board. No heat spreader is fitted, so clearance inside dense chassis is not affected. Installation typically takes minutes; the owner's manual should be consulted for population rules and BIOS settings. Mixing with unregistered or non-ECC modules is not supported.

Questions about this item

How much power does the 1.2 V DDR4 3200 module draw under continuous server load?

The module operates at 1.2 V with CL22 latency; registered ECC RDIMMs at this voltage typically run cool and draw minimal power during all-day workloads.

What motherboard slot and chipset are required for this 288-pin 2Rx4 RDIMM to function?

It needs a Supermicro H11SSL-NC or compatible AMD EPYC server board with DDR4 RDIMM slots and registered ECC support.

Will this CL22 3200 MHz stick run stably alongside slower DDR4 modules already installed in the same system?

The memory will down-clock to match the slowest installed module while maintaining ECC and registered operation for stability.
