NEMIX RAM 768GB 6x128GB DDR5 5600 CL46 ECC RDIMM Supermicro H13SSF memory upgrade

SKU CH-CMP8-3M58R

Six 128 GB DDR5 ECC registered DIMMs deliver 768 GB at 5600 MT/s with CL46 latency for the Supermicro H13SSF motherboard

  • Total capacity768 GB (6 × 128 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 768 GB total capacity across six 128 GB modules for maximum server memory density
  • DDR5 5600 speed with CL46 latency delivers rated throughput without down-clocking
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the motherboard's voltage spec for reliable start-up
  • 288-pin RDIMM form factor fits the Supermicro H13SSF memory slots exactly

Exact-match DDR5 upgrade kit

This 768 GB kit contains six 128 GB DDR5 5600 RDIMM modules built to the PC5-44800 standard. Registered ECC architecture with CL46 timing and 1.10 V operation matches the Supermicro H13SSF memory controller so the system recognises full capacity at rated speed.

Thermals noise and power draw

Bare modules without heat spreaders rely on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all slots are populated. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

Bundled accessories and software

The package delivers only the six RDIMM modules in a single kit. No additional cables, brackets or software utilities are included. Installation follows the motherboard manual population rules for full-capacity operation.

Questions about this item

How do I install the 288-pin RDIMM modules on the Supermicro H13SSF and what step is often missed?

Power down, open the chassis, and insert each 128GB module into the DIMM slots following the motherboard's population order; the step often missed is verifying the BIOS recognises all 768GB at DDR5 5600 CL46 after first boot.

What maintenance or replacement will the 6x128GB DDR5 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement only occurs if a DIMM fails, which is covered by the lifetime replacement warranty.

What limit appears first when the 768GB kit runs sustained workloads at 5600 MT/s?

The registered ECC architecture offloads the memory controller, allowing all six slots to run fully populated at the rated 1.1V without throttling, so no thermal or electrical limit is reached under normal sustained use.
