NEMIX RAM DDR5 48GB 6400MHz CL52 2Rx8 1.1V ECC Registered RDIMM 288-Pin memory upgrade

SKU CH-52BE-XZ8RZ

48GB DDR5 6400MHz CL52 2Rx8 1.1V ECC registered RDIMM validated for Supermicro H14SSF motherboards

  • Total capacity48 GB
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 48 GB capacity lets you run larger workloads in a single module
  • DDR5 6400 speed delivers high bandwidth for demanding server tasks
  • CL52 latency and 1.1 V voltage match the memory controller timing for stable operation
  • 2Rx8 registered ECC design offloads the controller and corrects single-bit errors on the fly
  • 288-pin RDIMM form factor fits the Supermicro H14SSF motherboard exactly

Exact-match server upgrade

This 48GB DDR5 6400MHz CL52 Registered ECC RDIMM is built for the Supermicro H14SSF motherboard. The 2Rx8 1.1V module matches the board's required rank, voltage and timing so the controller recognises full capacity at rated speed. It targets administrators who need enterprise stability in a single-slot population.

Replaces lower-capacity or unbuffered DDR5

Swapping a UDIMM or smaller RDIMM for this 48GB registered module lets every populated slot run at the full PC5-51200 data rate while ECC corrects single-bit errors on the fly. The jump is worth it when the manual approves 48GB per slot and the workload cannot tolerate silent data corruption or unplanned reboots.

Tool-free DIMM installation

Align the 288-pin key, press until the retention clips click, then verify population order in the system manual. The most common issue is mixing registered and unbuffered modules or filling slots in an unsupported sequence, which prevents the server from posting at the rated 6400MHz speed.

Questions about this item

Will the 288-pin RDIMM fit my Supermicro H14SSF motherboard slots?

Yes, the 288-pin Registered RDIMM form factor matches the slots required by the Supermicro H14SSF motherboard.

What BIOS setting or population order is critical when installing this 2Rx8 DDR5 module?

Follow the motherboard manual for approved DIMM population order and enable ECC Registered mode so the controller recognises the 2Rx8 rank at 6400 MHz.

Does the lack of a heat spreader on this 1.1V DDR5 module affect long-term reliability?

The module runs at the standard 1.10 V DDR5 voltage and uses major OEM chips rated for continuous server operation without a spreader.
