64 GB DDR5 ECC RDIMM for Supermicro servers

This 64 GB DDR5 5600 registered DIMM adds error-correcting memory to compatible Supermicro SuperServer systems. It is built for workstations, NAS appliances, servers and network switches that require ECC registered modules. Standard desktop computers cannot use this memory.

Installation notes and common issues

The module fits a 288-pin DDR5 slot and installs like any DIMM, but it must not be mixed with unbuffered or load-reduced ECC memory. Systems that require registered DIMMs will not post if the wrong type is populated. Verify the server manual for population rules and rank limits before adding this module.

Compatibility checklist before ordering

Confirm your Supermicro model matches one of the listed SuperServer part numbers: SYS-821GE-TNHR, SYS-821GV-TNR, SYS-E403-13E-FRN2T, SYS-F511E2-RT or SYS-F521E3-RTB. Check that the platform supports DDR5 5600 registered ECC at 1.1 V and that the memory controller accepts 2Rx4 organisation. Ensure no unbuffered or load-reduced DIMMs are already installed.

Questions sur cet article

How do I verify the 64GB DDR5 5600 ECC RDIMM is running at PC5-44800 CL46 after installation?

Enter the server BIOS or UEFI and confirm the memory speed shows 5600 MT/s, CAS latency 46, voltage 1.1 V and that ECC Registered mode is active for the installed module.

What ships with the OWC 5R6D52R464GB module and what must be sourced separately?

The package contains the single 64 GB 288-pin DDR5 ECC Registered DIMM only; no heat spreader, cables, tools or additional DIMMs are included.

Which capacity and rank should I choose for a Supermicro SuperServer SYS-821GE-TNHR upgrade?

This part is a single 64 GB 2Rx4 Registered ECC DIMM; select it when the server requires a 64 GB module at DDR5 5600 CL46 1.1 V and the memory slots accept 2Rx4 registered memory.
