SAMSUNG 128GB 4x32GB DDR4 2666MHz RDIMM Server Memory

SKU CH-8CYC-2GWJ3

Four 32 GB DDR4 RDIMMs running at 2666 MHz deliver 128 GB of registered server memory

  • 128GB total capacity across four 32GB modules
  • Registered DDR4 design improves signal integrity for servers
  • 2666MHz speed with PC4-21300 bandwidth rating
  • RDIMM form factor fits standard server DIMM slots
  • Samsung M393A4K40CB2-CTD modules built for enterprise workloads

128GB DDR4 RDIMM kit

This Samsung kit supplies 128GB of registered DDR4 server memory across four 32GB modules. It targets administrators who need high-capacity, error-correcting RAM for multi-socket platforms.

Registered RDIMM form factor

Each DIMM carries part number M393A4K40CB2-CTD and operates at 2666MHz under the PC4-21300 specification. The registered buffer is the single attribute that determines compatibility with registered-only memory slots.

Four-module server population

The bundle fills four RDIMM slots in a single transaction, freeing the installer from sourcing matched sticks separately. It requires a motherboard that accepts registered DDR4 modules and cannot be used in systems limited to unbuffered UDIMM memory.

Perguntas sobre este artigo

What does 2666MHz mean for actual server workloads?

The rated 2666MHz speed sets the maximum data rate the memory controller can use; real-world throughput depends on the platform's memory controller and how many channels it populates.

What does PC4-21300 tell me about the DDR4 interface?

PC4-21300 is the JEDEC designation for DDR4-2666; it defines the peak transfer rate the DIMMs are validated to reach on a compliant memory bus.

Will these RDIMMs fit in a standard server DIMM slot?

Each module uses the RDIMM form factor, which matches the keyed DDR4 DIMM sockets found in registered-memory server platforms.
