64 GB DDR5 4800 ECC RDIMM

This 64 GB DDR5 4800 registered DIMM adds ECC-protected capacity to a Dell PowerEdge XE8640 rack server. The module runs at PC5-38400 speed with CL40 latency and operates at 1.1 V. It uses a 2Rx4 organisation on a 288-pin form factor without a heat spreader.

Suited for XE8640 memory expansion

IT teams scaling memory in a Dell PowerEdge XE8640 will find this module validated for that platform. Buyers needing unbuffered UDIMMs, non-ECC memory, lower-density sticks or a different server model should look elsewhere.

Fills a 288-pin DDR5 RDIMM slot

The stick plugs directly into an available DDR5 RDIMM slot on the XE8640 motherboard and draws power at the standard 1.1 V. No extra cooling hardware or adapters are required, leaving other slots free for further upgrades.

Questions about this item

Does my Dell PowerEdge XE8640 need a specific BIOS version to recognise the 64GB DDR5 4800 CL40 ECC RDIMM?

The module is validated for the Dell PowerEdge XE8640; install it in a supported slot and the system will detect the 64GB capacity at 4800 MT/s with CL40 timing.

Can I keep my existing DDR5 4800 ECC RDIMMs and add this 64GB 2Rx4 module without changing the memory configuration?

Yes, if the installed modules are also DDR5 4800 ECC RDIMMs the server will train all channels to 4800 MT/s; mixed ranks are supported per Dell's memory population rules.

How do I confirm the new 64GB DDR5 4800 CL40 ECC RDIMM is running at the correct speed and voltage after installation?

Enter the BIOS or iDRAC and verify the memory shows 64GB, 4800 MT/s, 1.1 V and ECC active for the new module.
