NEMIX RAM 48GB DDR5 6400 CL52 2Rx8 ECC RDIMM Supermicro H13SRH memory upgrade

SKU CH-FKS9-83TCR

48GB DDR5 6400 CL52 2Rx8 ECC registered RDIMM built for Supermicro H13SRH servers

  • Capacity48GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 48 GB capacity lets the H13SRH run fully populated at rated speed
  • DDR5-6400 CL52 timing matches the board's memory controller for immediate recognition
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 1 V operation at 2Rx8 rank fits the motherboard's voltage and population rules
  • 288-pin RDIMM form factor is the exact slot type the Supermicro H13SRH requires

48GB DDR5-6400 ECC RDIMM for Supermicro H13SRH

This 48GB DDR5 registered DIMM runs at 6400 MT/s with CL52 latency at 1.1 V. It is built for the Supermicro H13SRH motherboard and uses the 288-pin RDIMM form factor that board requires. The module delivers error-correcting, registered memory for server workloads.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM design with 2Rx8 rank structure. This matches the memory controller expectations of the H13SRH so every populated slot operates at the rated 6400 speed without down-clocking. A UDIMM or SODIMM would not be recognised by this platform.

Suited for admins expanding H13SRH capacity

System administrators adding memory to a Supermicro H13SRH will find the exact rank, voltage and timing the board expects. Builders needing unbuffered UDIMMs, non-ECC modules or a different pin count should look elsewhere because those types are physically and electrically incompatible with this server board.

Questions about this item

What does the 6400 speed rating mean when this module is installed in a Supermicro H13SRH server?

The DDR5 6400 (PC5-51200) rating is the exact data rate the memory controller expects, so the module runs at its full 6400 MT/s without down-clocking.

How does the registered ECC design affect signal integrity on this 288-pin RDIMM?

The registered architecture buffers address and command signals, reducing electrical load on the memory controller, while ECC corrects single-bit errors on the fly.

What physical slot and clearance does this 48GB kit require on the H13SRH motherboard?

It uses a standard 288-pin DDR5 RDIMM slot; with no heat spreader, the low-profile height fits dense server chassis without clearance issues.
