NEMIX RAM

NEMIX RAM 768GB (6x128GB) DDR4 2933MHz PC4-23400 CL21 1.2V 288-Pin ECC RDIMM Server RAM

SKU CH-4EF0-7JVY9

A 768 GB DDR4-2933 ECC registered kit of six 128 GB modules at CL21 1.2 V for server workloads

  • Capacity768GB (6 x 128GB)
  • Type288-Pin DDR4 RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V
  • ECCYes

Capacity 768GB (6 x 128GB)

  • 768 GB total capacity for memory-intensive server workloads
  • Six 128 GB DDR4 modules populate all channels
  • Registered ECC RDIMM design detects and corrects data errors
  • 2933 MHz PC4-23400 speed with CL21 latency
  • 2 V operation reduces power draw in dense configurations

High-Capacity DDR4 Server Kit

This 768GB kit contains six 128GB DDR4 RDIMM modules designed for enterprise servers and workstations. ECC and registered buffering protect data integrity in mission-critical environments. It targets IT professionals who need maximum memory density per channel.

DDR4 2933 Interface Constraints

The PC4-23400 standard sets the transfer rate at 2933 MT/s with CL21 latency at 1.2V. Registered modules add one cycle of address-command delay, which the memory controller must support. Total bandwidth is limited by the DDR4 bus width and this rated frequency.

768GB Capacity and Headroom

Six 8Rx4 ranks per module deliver the full 768GB across six slots, ideal for large virtualisation hosts and in-memory databases. Population rules for 8Rx4 DIMMs may reduce maximum speed on some platforms when all channels are filled. Systems requiring more capacity or higher frequency must use a different memory generation.

Questions about this item

Should I choose the 6x128GB kit or look for a different capacity?

The kit provides 768GB total across six 128GB modules, filling six DIMM slots. Choose it when your server board supports that population and you need the maximum registered ECC capacity.

What does the 2933MHz rating mean once installed in a server?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency at 1.20V, delivering that throughput only if the CPU memory controller and motherboard firmware enable the rated speed.

How does the 288-pin DDR4 RDIMM interface limit what I can use this with?

The 288-pin registered DDR4 form factor fits only DDR4 RDIMM slots; it will not work in UDIMM, LRDIMM, DDR5 or any other memory socket type.
