Capacity & compatibility

This Brute Networks module delivers 64GB of DDR5-5600 registered ECC memory in a single RDIMM. It is built to match HPE part number P64707-B21 and uses major-brand chipsets for full compatibility with supported HPE servers.

Suitable builds and limits

The part suits administrators expanding memory in qualified HPE platforms that accept 2Rx4 registered DDR5 RDIMMs. It is not for systems limited to unbuffered UDIMMs, for boards that cap per-slot capacity below 64GB, or for any desktop or consumer motherboard.

Deciding specification

The registered ECC RDIMM form factor with 2Rx4 organisation is the single attribute that determines whether this module will function in a given server; only platforms explicitly qualified for this configuration will recognise and utilise the full 64GB capacity.

Questions about this item

How much heat does a 64GB DDR5-5600 registered ECC module generate during continuous server workloads?

The module uses DDR5 architecture with a 2Rx4 registered design, which operates at standard DDR5 voltages for lower power draw per gigabyte compared to earlier generations.

What server platform must I already own for this HPE-compatible P64707-B21 64GB RDIMM to function?

You need an HPE server that supports DDR5-5600 registered ECC memory and accepts 2Rx4 PC5-44800 RDIMMs in its DIMM slots.

Can I mix this 64GB 2Rx4 DDR5-5600 RDIMM with smaller DDR5 registered ECC modules already installed in my HPE server?

Yes, provided the server supports mixed-capacity DDR5 registered ECC populations and the memory controller can handle 2Rx4 organisation alongside other ranks at 5600 MT/s.
