NEMIX RAM

NEMIX RAM 256GB (4 x 64GB) DDR4 3200 PC4-25600 4Rx4 1.2V ECC RDIMM server RAM

SKU CH-1THH-2XK09

Four 64 GB DDR4 registered ECC modules at 3200 MHz with CAS 22 and 1.2 V for server upgrades

  • Total capacity256 GB (4 × 64 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latency22
  • Rated voltage1.2 V
  • Buffer typeRegistered
  • 256 GB total capacity across four 64 GB modules for large server workloads
  • DDR4 3200 speed rated at PC4-25600 for high-throughput data paths
  • ECC registered design detects and corrects single-bit errors to protect data integrity
  • 4Rx4 organisation with major OEM chips delivers dense, reliable memory ranks
  • 2 V operation reduces power draw in multi-DIMM configurations

Server Memory Kit

This 256GB kit contains four 64GB DDR4 3200MHz registered DIMMs built for enterprise servers that require ECC error correction. The modules operate at 1.2V and use a 288-pin RDIMM form factor with 4Rx4 organisation.

Capacity and Headroom

Four ranks per module provide high density for virtualisation hosts and database workloads that benefit from large memory pools. CAS latency of 22 and the PC4-25600 rating set the performance envelope for sustained throughput.

DDR4 Interface Limits

The DDR4 3200 standard caps transfer rates at 25600 MT/s, so this kit cannot exceed that bandwidth regardless of processor capability. Registered buffering adds a cycle of latency but enables the high module count required for 256GB configurations.

Questions about this item

Will the 4Rx4 288-PIN DDR4 3200 modules work in a server that currently runs 2Rx4 RDIMMs at the same speed?

Yes, 4Rx4 and 2Rx4 RDIMMs can mix on DDR4 3200 platforms if the motherboard supports both rank configurations; populate identical ranks per channel for best stability.

How can I confirm the kit is running at PC4-25600 with ECC active after installation?

Check the BIOS memory information screen — it should report 3200 MT/s, CAS 22, 1.2 V and show ECC enabled for all 256 GB across the four 64 GB modules.

Does the box contain only the four 64 GB RDIMMs or are extra items such as heatsinks or cables included?

The kit includes only the four 64 GB 288-PIN ECC RDIMMs; no heatsinks, cables or additional accessories are supplied.
