Dell PowerEdge ECC RDIMM Upgrade

This OWC 16GB DDR5 4800 CL40 1Rx8 288-pin 1.1V ECC Registered RDIMM is built for Dell PowerEdge R6625, R760, R7615 and R7625 servers. It delivers error-correcting registered memory for workloads that require data integrity. The module follows JEDEC DDR5 specifications at PC5-38400 speed.

Workstation and server builds only

This memory suits administrators upgrading or repairing the listed PowerEdge models. It will not work in standard desktop computers, consumer workstations or any system that requires unbuffered or load-reduced DIMMs. Mixing with those memory types is not supported.

Registered ECC DDR5 at 4800 MT/s

The single specification that decides fit is the registered ECC DDR5 4800 CL40 1.1V 288-pin RDIMM form factor. Only systems qualified for this exact module type and speed will accept it.

Questions about this item

Does my Dell PowerEdge R760 need to support ECC Registered DDR5 at 4800 MT/s for this 16GB module to work?

Yes. The module is an ECC Registered DDR5 DIMM rated at 4800 MT/s CL40 1.1V, and the R760 is listed as a compatible system, so the server must accept that exact specification.

Can I add this 1Rx8 16GB RDIMM alongside existing DDR5 4800 ECC Registered modules in my R7625?

Yes, provided the installed memory is also DDR5 4800 ECC Registered. The product notes state it cannot be mixed with unbuffered or load-reduced ECC, but matching registered modules of the same speed and voltage will operate together.

How do I confirm the module is running at 4800 MT/s with ECC active after installation?

Check the system BIOS or iDRAC memory configuration screen; it should show each DIMM at 4800 MT/s, 1.1V, with ECC Registered status and the correct 16GB capacity per module.
