256GB DDR4 2933MHz ECC RDIMM

This single 256GB module delivers DDR4 2933MHz PC4-23400 speed with ECC and registered buffering for server platforms that require data integrity. It is built for enterprise workloads needing maximum capacity per slot and is not intended for standard desktop computers.

Thermals noise and power draw

Operating at 1.2V standard DDR4 voltage the module runs within typical server thermal envelopes without active cooling on the DIMM itself. Registered buffering reduces electrical load on the memory controller helping keep system power draw predictable during normal operation.

Sustained load behavior

The 8Rx4 organisation and CAS latency 21 support consistent throughput for long-running compute or virtualisation tasks. ECC correction maintains data accuracy across extended sessions while the registered design stabilises signalling on heavily populated memory channels.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and which step is often missed?

Align the notch on the module with the key in the slot, press firmly until both retention clips click, then verify the server BIOS recognises the full 256GB capacity and the registered buffer initialises correctly.

What maintenance or replacement will this ECC RDIMM need over its service life?

The module itself has no user-serviceable parts; plan to replace it only if the server logs uncorrectable ECC errors or if a firmware update requires a different rank configuration.

What limit appears first when this 8Rx4 module runs at 2933MHz under sustained load?

The memory controller’s maximum supported rank-per-channel limit is typically reached before thermal or bandwidth constraints, so confirm the platform supports 8Rx4 at full speed.
