Dell PowerEdge R760xa DDR5 kit

This NEMIX RAM kit provides 256 GB of DDR5 4800 memory for the Dell PowerEdge R760xa. Two 128 GB modules operate at 1.1 V with CL40 latency and 4Rx4 organisation. ECC and registered buffering are built in for server reliability.

Suited for R760xa capacity upgrades

IT teams expanding a Dell PowerEdge R760xa will match the server's qualified DDR5 4800 specification. Systems that require unbuffered DIMMs, lower voltage, or a different pin count cannot use these modules.

Verify R760xa memory rules

Confirm the R760xa supports 4Rx4 registered DIMMs at this density and that the planned population order follows Dell's slot guidelines. Ensure the BIOS revision accepts 256 GB kits before installation.

Questions about this item

What server is required for this 256 GB DDR5 4800 ECC RDIMM kit to work?

It is validated for the Dell PowerEdge R760xa rack server and will operate in that platform with the correct memory configuration.

Will this 4Rx4 registered DDR5 kit run at its rated 4800 MT/s if the R760xa already has slower DDR5 modules installed?

The server memory controller will negotiate a common speed; all populated slots typically run at the lowest rated module speed present.

How can I confirm the kit is running at DDR5 4800 with CL40 timings after installation?

Check the system BIOS or iDRAC memory inventory; it will report each module at 4800 MT/s, CL40, 1.1 V, registered ECC operation.
