Green 288-pin DDR4 RDIMM module with black DRAM chips

SK hynix

SK hynix HMA82GR7CJR4N-WM 16GB 1Rx4 PC4-2933Y DDR4 server RAM

SKU CH-2XCW-9CE2V

16 GB DDR4 registered ECC RDIMM running at 2933 MHz for server workloads

  • 16 GB registered ECC capacity for reliable server workloads
  • DDR4 2933 MHz speed supports high-throughput data tasks
  • Single-rank 1Rx4 layout simplifies memory-channel population
  • 2 V operating voltage reduces platform power draw
  • 288-pin RDIMM form factor fits standard server DIMM slots

16 GB DDR4 RDIMM for servers

This 16 GB registered DIMM uses DDR4 technology at 2933 MHz and includes ECC error correction. It is built for servers and workstations that require registered memory with single-rank organisation.

Check 288-pin DDR4 RDIMM slots and voltage

Verify that your motherboard accepts 288-pin DDR4 RDIMM modules and operates at 1.2 V. The module is a registered design with one rank, so the platform must support registered ECC memory in this configuration.

Steady throughput with registered ECC

The registered buffer and ECC circuitry maintain data integrity during continuous workloads. Single-rank organisation across eighteen FBGA DRAMs allows consistent bandwidth without the timing penalties that can appear in multi-rank configurations under sustained load.

Questions about this item

Does the HMA82GR7CJR4N-WM come as a single 16 GB stick or do I need to buy anything else to install it?

It is supplied as one 16 GB RDIMM. No extra parts are required for installation beyond a compatible DDR4 DIMM slot.

How do I decide between the 1Rx4 organisation and other rank options for this module?

The module uses a single-rank 1Rx4 layout with eighteen 2 Gb x4 DRAMs, giving 16 GB capacity at 2933 MT/s while leaving additional slots free for future expansion.

What does the 2933 MT/s rating mean for actual throughput in a server?

At 2933 MT/s the module transfers data at the PC4-23466 rate, providing the bandwidth specified for DDR4-2933 when the platform runs the memory at that speed.
