Four green DDR4 ECC RDIMM modules with gold contacts and black heat spreaders

NEMIX RAM

NEMIX RAM 64GB (4x16GB) DDR4 2933 ECC RDIMM 2Rx8 1.2V

SKU CH-X41H-A2JG9

A 64GB server memory kit of four 16GB DDR4 2933 ECC registered DIMMs running at 1.2V with CL21 latency

  • Total capacity64 GB (4 × 16 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latency21
  • Rated voltage1.2 V
  • Buffer typeRegistered
  • 64 GB kit delivers high server capacity with four 16 GB modules
  • ECC registered design detects and corrects memory errors for reliable uptime
  • DDR4 2933 MT/s speed provides fast data throughput at PC4-23400 bandwidth
  • Low 1.2 V operation reduces power draw and heat in dense chassis
  • Dual-rank 2Rx8 organisation on 288-pin RDIMMs maximises density per channel

Server DDR4 2933 kit

This 64 GB kit contains four 16 GB DDR4 2933 modules rated at PC4-23400 with CAS latency 21. Each stick is a 2Rx8 registered ECC DIMM operating at 1.2 V on a 288-pin form factor. It is built for servers that require registered error-correcting memory and is not suitable for standard PC platforms.

Capacity and headroom

The 64 GB total capacity provides ample headroom for multi-threaded workloads, virtualization hosts and database buffers that benefit from large, error-corrected memory pools. Four dual-rank modules fill four slots, so expansion beyond this kit requires free DIMM sockets on the motherboard.

DDR4 2933 interface limits

The DDR4 2933 interface caps transfer rates at PC4-23400, so bandwidth is bounded by this specification regardless of processor capability. Registered signalling adds a clock cycle of latency versus unbuffered designs, and the 1.2 V operating voltage is fixed for this standard.

Questions about this item

Will this DDR4 2933 kit run at full speed alongside my existing DDR4 modules?

The kit is rated for DDR4 2933 (PC4-23400) at CAS 21. If paired with slower DDR4 modules, the system typically downclocks all memory to the lowest common speed, so the 2933 MHz rating will not be maintained.

How can I verify the ECC registered function is active after installing these 288-pin RDIMMs?

Enter the server BIOS or use a hardware inventory tool such as IPMI or dmidecode. Look for ECC status reported as enabled and memory type shown as Registered DDR4 2933 with 2Rx8 organisation across all four 16 GB modules.

Does the box contain only the four 16 GB RDIMMs or are extra items included?

The package supplies the four 16 GB DDR4 2933 ECC RDIMM modules (288-pin, 1.2 V, 2Rx8). No heatsinks, cables, software or additional accessories are included.
