Four green DDR5 RDIMM modules in a kit

NEMIX RAM

NEMIX RAM DDR5 128GB 4x32GB 5600 CL46 ECC RDIMM Supermicro H13SSH-E memory upgrade

SKU CH-QRJM-GM6R2

A 128 GB DDR5 registered ECC kit of four 32 GB modules running at 5600 MT/s with CL46 latency and 1.1 V operation, validated for the Supermicro H13SSH-E motherboard

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 128 GB total capacity with four 32 GB modules for high-density server workloads
  • DDR5-5600 speed rated at PC5-44800 for fast data throughput
  • CL46 CAS latency and 1.1 V operation tuned for registered ECC stability

Exact-match DDR5 ECC RDIMM kit for Supermicro

This 128GB kit ships as four 32GB modules built to the DDR5 5600 standard with CL46 timing and 1.1V operation. Registered ECC architecture and 2Rx8 organization match the memory controller expectations of the Supermicro H13SSH-E motherboard so the full capacity is recognized at rated speed. It is intended for administrators upgrading that specific server platform.

Replaces partial or slower memory configurations

The jump is worth it when your current DIMMs leave slots empty, run at a lower data rate, or lack ECC and registered buffering. Populating all channels with matched 2Rx8 RDIMMs lets the controller operate at the full 5600 MT/s spec while ECC corrects single-bit errors before they affect workloads. Builders who need a different form factor, non-ECC UDIMMs, or capacities beyond this kit's 128GB total should look elsewhere.

Verify motherboard population rules

Consult the Supermicro H13SSH-E manual for the approved DIMM installation sequence, maximum supported capacity per slot, and any BIOS version requirements. The 288-pin RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit. Confirm that your chassis and airflow design accommodate four full-height modules without clearance issues.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SSH-E motherboard DIMM slots?

Yes. The kit uses the 288-pin Registered DDR5 RDIMM form factor that the H13SSH-E requires; it is not a UDIMM or SODIMM and matches the board's physical slot layout.

What is the correct installation order for the four 32 GB modules on the H13SSH-E?

Populate all four slots following the motherboard manual's DIMM population sequence so the memory controller recognises the full 128 GB at DDR5-5600.

Does the kit include a heat spreader that could require cleaning or replacement later?

No. The modules ship without a heat spreader, so there is no spreader to maintain or replace during the product's lifetime.
