Eight green DDR4 RDIMM sticks with black chips and gold contacts

SAMSUNG

SAMSUNG 256GB (8 x 32GB) DDR4 2666MHz RDIMM Server Memory

SKU CH-X46X-6105M

256 GB registered DDR4 server kit with eight 32 GB modules running at 2666 MHz CL19

  • 256 GB total capacity from eight 32 GB modules
  • 2666 MHz DDR4 speed for responsive server workloads
  • Registered RDIMM design improves signal integrity on multi-DIMM channels
  • CL 19 CAS latency balances timing and throughput
  • 288-pin form factor fits standard DDR4 server slots

Server-grade capacity

This bundle provides 256GB of DDR4 registered memory across eight 32GB RDIMM modules. It is built for multi-socket servers and workstations that require large memory footprints for virtualization, databases or high-performance computing workloads.

Registered buffering and CL19 timing

Each module uses registered signal buffering to reduce electrical load on the memory controller, allowing the full eight-module population. The CL19 CAS latency and 2666MHz speed rating define the access timing for sustained throughput in compatible server platforms.

Keyed 288-pin installation

The 288-pin RDIMM form factor fits only server motherboards with registered DIMM slots; desktop boards will not accept these modules. Installers must populate slots in the order specified by the system manual, as incorrect population order is the most common cause of boot failure.

Questions about this item

Will any of the eight 32 GB RDIMMs need replacement under normal server duty?

The modules are new DDR4 registered DIMMs with no moving parts; they do not require scheduled replacement unless a hardware fault occurs.

What is the first limit reached when the 256 GB kit runs at 2666 MHz continuously?

The registered buffer and CL 19 latency set the timing boundary, so sustained throughput is capped by the DDR4 2666 MHz specification.

How much heat and noise do the 288-pin RDIMMs produce during all-day operation?

The DIMMs generate only modest heat and are completely silent; server chassis airflow handles cooling without extra noise.
