Two green DDR5 server memory modules with gold contacts and black chips, no heat spreader

NEMIX RAM

NEMIX RAM 256GB (2x128GB) DDR5 4800 ECC RDIMM Server RAM

SKU CH-QPH4-QSF79

A 256 GB DDR5 server kit of two 128 GB ECC registered DIMMs running at 4800 MT/s with CL40 latency and 1.1 V operation

  • Capacity256GB (2 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.10V
  • ECCYes

Capacity 256GB (2 x 128GB)

  • 256 GB total capacity from two 128 GB modules
  • DDR5 4800 MT/s speed rated at PC5-38400 bandwidth
  • ECC registered design detects and corrects single-bit errors
  • Low 1.10 V operating voltage reduces server power draw
  • Built with major OEM Samsung Micron Hynix DRAM chips

256GB DDR5 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR5 ECC RDIMM modules built for servers and workstations that require registered memory with error correction. The 4Rx4 organisation and 1.10V operating voltage target enterprise platforms designed for high-density memory configurations. Buyers deploying virtualisation hosts, database nodes or compute clusters will match the capacity and reliability profile.

Platform Requirements Check

Verify that your motherboard supports DDR5 RDIMM modules, registered operation and 4Rx4 rank density at 4800 MT/s. The memory controller must accept 288-pin ECC registered DIMMs at 1.10V and the BIOS must be current enough to initialise the full 256GB capacity. Systems limited to UDIMM, lower rank counts or slower speeds will not post with this kit.

Build Integration

The modules occupy two DIMM slots and leave remaining channels free for further expansion up to the platform limit. Registered buffering reduces electrical load on the memory controller, helping stability when all slots are populated. No heat spreaders are fitted, so airflow across the bare PCBs must be provided by the server chassis cooling design.

Domande su questo articolo

Does the 256 GB kit include two 128 GB modules or do I need to buy extra sticks?

The kit ships with two 128 GB DDR5 RDIMM modules for a total of 256 GB.

Should I choose the 4Rx4 4800 MT/s version or a different rank and speed?

This kit is 4Rx4 at 4800 MT/s; select it when your server requires registered ECC DDR5 at that rank and data rate.

What does the CL40 latency mean once the memory is installed in a server?

CL40 indicates 40 clock cycles of CAS latency at the rated 4800 MT/s speed, which the memory controller uses for timing.
