256 GB DDR4-2933 ECC Kit

This 256 GB kit contains two 128 GB registered DDR4 modules rated at 2933 MT/s with CL21 latency. It is built for servers and workstations that require error-correcting memory to protect data integrity in production workloads.

Thermals, Noise and Power Draw

Operating at 1.2 V, the modules draw minimal power and generate little heat inside a server chassis with directed airflow. No active cooling is present on the DIMMs themselves, so system fans determine the acoustic profile.

Major-Brand DRAM and Lifetime Support

Chips from Samsung, SK Hynix or Micron are selected and tested for stability under sustained load. The vendor provides a lifetime replacement warranty and access to technical support staff who specialise in memory upgrades.

Questions about this item

How do I install the 288-pin RDIMM modules, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, and verify the server BIOS detects the full 256 GB capacity after POST.

What maintenance or replacement will the 128 GB modules need later?

No routine maintenance is required; if a module fails it is replaced under the manufacturer lifetime warranty, and no other components wear out.

What limit appears first under sustained load with CL21 latency and 1.2 V operation?

The CAS latency of 21 cycles at 2933 MT/s sets the minimum access delay, which becomes the bottleneck before voltage or thermal limits are reached.
