64GB DDR5 ECC RDIMM for Supermicro

This 64GB DDR5 5600 registered DIMM delivers ECC protection for Supermicro motherboards including B13DEE, B13DET, B13SEE-CPU-25G and B13SEG. The module runs at PC5-44800 speed with CL46 latency and 1.1V operation. It is built for workstations, servers and NAS systems that require registered memory.

Workstation and server builders needing registered

Buyers upgrading compatible Supermicro platforms gain a single 64GB module that meets JEDEC standards. Systems requiring unbuffered or load-reduced ECC cannot use this RDIMM. Desktop computers without registered memory support are also unsuitable.

Registered ECC requirement decides compatibility

The module is an ECC registered RDIMM and will not function in platforms that accept only unbuffered or load-reduced memory. Verify that your Supermicro motherboard explicitly supports registered DIMMs before purchase.

Questions about this item

How much power does the 1.1V DDR5 5600 module draw when the server runs continuously?

The module operates at 1.1V, the standard DDR5 voltage, which helps limit heat output during all-day workloads in compatible Supermicro systems.

Which motherboard must the system already have for this 64GB RDIMM to function?

It is validated for Supermicro motherboards B13DEE, B13DET, B13SEE-CPU-25G and B13SEG; the board must support DDR5 ECC registered memory.

Can this 2Rx4 registered DIMM share channels with older unbuffered ECC sticks I kept from a previous build?

No, the manufacturer states it cannot be mixed with unbuffered or load-reduced ECC memory; all slots should use matching registered modules.
