64 GB DDR5 RDIMM for servers

This Micron module delivers 64 GB of DDR5 ECC memory in a single RDIMM. It is designed for server platforms that require registered DIMMs with error correction. The PC5-5600B rating indicates a 5600 MT/s data rate. Buyers needing higher capacity per slot will find this density suitable.

Check motherboard RDIMM support

Verify that the target system accepts DDR5 RDIMM modules and has a free DIMM slot. The module uses a 2Rx4 organisation, so the memory controller must support this rank configuration. Confirm the platform qualified vendor list for this specific part number before ordering. Mixed DIMM populations may affect maximum speed.

Single-module kit simplifies upgrades

The package contains one 64 GB stick, allowing precise capacity increments without buying matched pairs. No additional cables, brackets or software licences are included. Installation follows standard server DIMM procedures. The ECC feature operates automatically when the platform enables it.
