Capacity 256GB (8 x 32GB)

  • 256GB kit expands server capacity for heavy workloads using eight 32GB modules
  • ECC RDIMM detects and corrects single-bit errors to protect data integrity
  • Registered DIMM reduces electrical load on the memory controller for stable operation
  • DDR4 2133MHz at CL15 delivers 17000 MT/s bandwidth for responsive performance
  • 2V standard voltage lowers power draw and heat in dense configurations

Server Memory Kit

This 256GB kit contains eight 32GB DDR4 registered DIMMs built for servers and workstations that require ECC memory. The modules operate at 2133MHz with CL15 latency and 1.2V voltage. They are not compatible with desktop or laptop computers.

Thermals and Power

Each module runs at standard DDR4 1.20V, keeping power draw low for dense 288-pin configurations. Registered buffering reduces electrical load on the memory controller, aiding stability in fully populated channels. No active cooling is included or required by the specification.

Upgrade Context

This kit replaces smaller-capacity DDR4 RDIMM sets when workloads demand 256GB of error-correcting registered memory. The jump is worthwhile for virtualization hosts, database servers or compute nodes that exceed the capacity of existing modules. Systems limited to lower speeds or unbuffered memory cannot use this kit.

Questions about this item

How do I install the 8x32GB DDR4 2133MHz ECC RDIMM kit and what step is often missed?

Power off the server, open the chassis, align each 288-pin module with the slot key, press firmly until the latches click, then consult the system manual for the correct channel population order for all eight modules.

What maintenance or replacement will the 256GB DDR4 ECC RDIMM kit need over time?

No scheduled maintenance is required; the modules have no moving parts, and ECC corrects single-bit errors on the fly. Replace a module only if the system logs uncorrectable errors or a memory diagnostic fails.

What limit appears first when the 2133MHz CL15 1.2V registered kit runs under sustained load?

The memory controller’s maximum supported speed and rank-per-channel limit will cap usable frequency or total capacity before the modules themselves reach a thermal or voltage ceiling.
