Capacity & Form Factor

This 64GB DDR5 module uses the standard 288-pin DIMM layout and operates at 1.10V. It provides a single high-density stick for server boards that accept registered memory. The 2Rx4 organisation helps the memory controller manage electrical loading across the channel.

Suited & Unsuitable Builds

The registered ECC design targets multi-socket servers and workstations running virtualisation or database workloads where data integrity matters. Desktop boards and consumer laptops that lack registered-buffer support cannot use this module and will not post with it installed.

Deciding Specification

The registered ECC signal processing is the single attribute that determines whether this part fits the platform; without a chipset and BIOS that explicitly support registered DDR5 the module will not function.

Questions about this item

Will this 288-pin DDR5 DIMM fit my server's memory slots?

The module uses the standard 288-pin DDR5 DIMM form factor. Verify your motherboard supports DDR5 registered ECC memory and has available 288-pin slots before purchasing.

What BIOS setting is often missed when installing this registered ECC module?

After seating the 2Rx4 registered DIMM firmly until the clips lock, enable ECC error correction in the BIOS; many builders forget this step and lose the data-integrity benefit.

Does the lack of a heat spreader mean I must replace the module sooner?

No. The bare PCB runs at the standard 1.10 V and CL40 latency. As long as chassis airflow meets the server vendor's specification, no scheduled replacement is required.
