Two green DDR5 RDIMM modules, bare chips, 288-pin, 256GB kit

NEMIX RAM

NEMIX RAM 256GB 2x128GB DDR5 5600MHz ECC RDIMM Supermicro H13SSF memory upgrade

SKU CH-MDDC-SGM92

256GB dual-rank DDR5-5600 ECC RDIMM kit validated for Supermicro H13SSF servers

  • Total capacity256 GB (2 × 128 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 256 GB capacity from two 128 GB modules for maximum server density
  • DDR5 5600 speed with CL46 timing delivers rated bandwidth out of the box
  • Registered ECC architecture corrects single-bit errors to prevent silent data corruption
  • 1 V operation reduces power draw across fully populated DIMM slots
  • 288-pin RDIMM form factor matches Supermicro H13SSF memory-population rules exactly

Exact-Match Server Upgrade

This 256GB kit delivers two 128GB DDR5 5600MHz ECC Registered RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSF motherboard expects. It is intended for administrators who need the full supported capacity recognised immediately and running at rated speed without manual tuning.

Verified Fitment and Stability

The modules use the 288-pin RDIMM form factor this board requires, not UDIMM or SODIMM, and are spec-matched to its memory-population rules. Registered architecture offloads the memory controller so every slot runs fully populated, while ECC catches and corrects single-bit errors on the fly to stop silent data corruption and unplanned reboots before they reach production.

Lifetime Support and Pre-Purchase Checks

The kit is backed by a lifetime replacement warranty and free US-based technical support. Buyers must consult their system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase, because server memory support varies by model and configuration.

Questions about this item

Does this DDR5-5600 RDIMM kit run at its rated 5600 MT/s on the Supermicro H13SSF, or does the board cap it lower?

The kit is spec-matched to the H13SSF so the memory controller recognises the exact rank, voltage and timing, allowing the modules to operate at the full DDR5-5600 (PC5-44800) data rate when populated per the board's rules.

What physical slot and form factor does this 256 GB kit require on the H13SSF motherboard?

It uses the 288-pin Registered RDIMM form factor that the H13SSF expects; UDIMM or SODIMM modules will not fit or function in these slots.

What is the correct installation sequence for the two 128 GB modules on this board?

Consult the H13SSF manual for the approved DIMM population order; the board's memory-population rules dictate which slots must be filled first to achieve full 256 GB capacity and rated speed.
