Green 288-pin DDR4 LRDIMM module with black chips, no heat spreader

NEMIX RAM

NEMIX RAM 64GB 1Rx64 DDR4 3200 PC4-25600 4Rx4 CL22 288-pin ECC LRDIMM for ASRock Rack ROMED8-2T

SKU CH-484Z-BBGJS

64 GB DDR4 ECC load-reduced DIMM running at 3200 MHz with CL22 latency for ASRock Rack ROMED8-2T EPYC servers

  • Capacity64GB
  • SpeedDDR4 3200 (PC4 25600)
  • ECCYes
  • Buffered/RegisteredLoad Reduced
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V

Capacity 64GB

  • 64 GB capacity supports memory-intensive server workloads
  • DDR4 3200 speed delivers high data throughput for EPYC platforms
  • ECC LRDIMM technology corrects errors and reduces electrical load on the memory bus
  • CL22 latency at 1.2 V balances responsive timing with efficient power use
  • 288-pin form factor ensures direct compatibility with the ASRock Rack ROMED8-2T motherboard

Server memory for EPYC platforms

This NEMIX RAM module delivers 64 GB of DDR4 ECC LRDIMM capacity for the ASRock Rack ROMED8-2T motherboard. It targets administrators who need registered load-reduced memory to maximise density on AMD EPYC server boards. The single-stick kit simplifies population rules for qualified configurations.

4Rx4 organisation at 3200 MT/s

The decisive specification is the 4Rx4 rank layout running at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V. This rank structure and speed grade must match the motherboard's qualified-vendor list; a different rank count or data rate will prevent the system from posting.

Tool-free DIMM installation

The 288-pin LRDIMM seats vertically in the board's memory slots with standard ejector levers and requires no heat spreader clearance. Common issues arise when mixing this 4Rx4 module with other rank types or when the BIOS is not updated to the revision that supports the full 64 GB density per slot.

Questions about this item

What does the 3200 speed mean when this module is installed in a server?

The module runs at 3200 MT/s, giving a peak transfer rate of PC4-25600 bandwidth for the memory controller.

How does the 288-pin DDR4 LRDIMM interface limit performance in practice?

The 288-pin DDR4 LRDIMM interface caps the module at 3200 MT/s and 1.20V, with ECC and load-reduced buffering for signal integrity.

What physical slot and clearance does this 64GB stick need to fit?

It needs a standard 288-pin DDR4 DIMM slot; the module has no heat spreader, so it fits in tight server chassis.
