NEMIX RAM 8GB DDR4 3200 ECC RDIMM SuperMicro H12SST-PS memory upgrade

SKU CH-HKJ0-3MCFT

8GB DDR4 3200 ECC registered DIMM for Supermicro H12SST-PS EPYC servers

  • Capacity8GB
  • SpeedDDR4 3200 (PC4 25600)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity on dense server boards
  • DDR4 3200 speed matches EPYC platform requirements
  • 2 V operation reduces power draw per module
  • 288-pin RDIMM form factor fits Supermicro H12SST-PS slots

Server Memory Upgrade

This NEMIX RAM module adds 8GB of DDR4 3200 ECC registered memory to a Supermicro H12SST-PS motherboard running AMD EPYC processors. The single 1Rx8 rank operates at 1.20V with CL22 latency and fits the 288-pin RDIMM slots without a heat spreader.

Capacity and Headroom

An 8GB stick suits light virtualization, file serving or development workloads that fit inside a modest memory footprint. Heavy database caches, large container fleets or memory-intensive rendering will exhaust this capacity quickly and require additional modules to scale.

Upgrade Context

The module replaces slower DDR4 DIMMs or fills empty slots on the H12SST-PS platform to reach the board’s supported speed. The jump is worthwhile when the system currently runs below 3200 MT/s or lacks ECC protection for data integrity.

Highlights

  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity on dense server boards
  • DDR4 3200 speed matches EPYC platform requirements
  • 2 V operation reduces power draw per module
  • 288-pin RDIMM form factor fits Supermicro H12SST-PS slots

Questions about this item

Will this DDR4 3200 RDIMM work in the same Supermicro H12SST-PS board alongside my existing 1.2 V ECC modules?

The module is a 1.2 V DDR4 3200 ECC RDIMM built for the H12SST-PS, so it matches the voltage and registered design of other qualified sticks for that platform.

How can I confirm the stick is running at CL22 3200 MT/s with ECC active after install?

Check the BIOS memory information screen for 3200 MT/s speed, CL22 timings and ECC status, then run a memory stress test to verify stability.

Does the package include only the 8 GB RDIMM or are there extra parts such as a heat spreader?

The box contains the single 8 GB 288-pin DDR4 RDIMM; no heat spreader or additional accessories are included.
