Four bare green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 512GB (4x128GB) DDR5 4800 PC5-38400 4Rx4 ECC RDIMM server RAM

SKU CH-88GK-NBRE7

Four 128 GB DDR5 4800 registered ECC modules deliver 512 GB at CL40 and 1.10 V for server workloads

  • Capacity512GB (4 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.10V

Capacity 512GB (4 x 128GB)

  • 512 GB total capacity across four 128 GB modules
  • DDR5 4800 speed rated at PC5-38400 bandwidth
  • ECC registered design detects and corrects memory errors
  • 1 V operation reduces server power draw
  • 288-pin RDIMM form factor fits standard DDR5 server slots

High-capacity server memory kit

This NEMIX RAM kit delivers 512GB of DDR5 ECC registered memory across four 128GB modules. It is built for enterprise servers and workstations that require maximum registered capacity with error correction. Systems needing unbuffered memory or desktop form factors cannot use these modules.

4Rx4 registered DDR5 at 4800 MT/s

Each module runs at DDR5 4800 (PC5-38400) with a CAS latency of 40 at 1.10V. The 4Rx4 organisation and registered buffer are the decisive specifications; the motherboard must explicitly support 4Rx4 registered DDR5 RDIMMs for the kit to function.

288-pin RDIMM kit for compatible platforms

The four 288-pin RDIMMs occupy four memory slots and draw 1.1V. They free the builder from mixing capacities or ranks, but they demand a platform qualified for 128GB 4Rx4 registered modules and sufficient slot count. No heat spreaders are included.

I korthet

  • 512 GB total capacity across four 128 GB modules
  • DDR5 4800 speed rated at PC5-38400 bandwidth
  • ECC registered design detects and corrects memory errors
  • 1 V operation reduces server power draw
  • 288-pin RDIMM form factor fits standard DDR5 server slots

Frågor om den här produkten

What does the 4800 MT/s speed mean once the modules are installed in a server?

The 4800 MT/s rating is the maximum data rate the memory controller can run at; actual throughput depends on the CPU and motherboard memory controller, which may operate at a lower speed if the platform does not support the full rate.

How does the 288-pin DDR5 RDIMM interface limit performance in practice?

The 288-pin RDIMM form factor carries DDR5 signals and the registered buffer, so the electrical interface caps the kit at the JEDEC DDR5-4800 standard and prevents use in slots wired for other DDR generations or unbuffered DIMMs.

What physical clearance and slot requirements does a 4Rx4 128 GB RDIMM need to fit?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits any DDR5 RDIMM slot with normal vertical clearance; the 4Rx4 organisation simply requires the motherboard to support quad-rank registered DIMMs.
