64 GB DDR4 ECC RDIMM for Dell PowerEdge R7525

This 64 GB DDR4 3200 MHz ECC registered DIMM is built for the Dell PowerEdge R7525 rack server. It runs at 1.2 V with CL22 latency and a 2Rx4 rank layout on a 288-pin module. The part number MR25600-924K1 identifies the exact specification for this platform.

Suited for administrators expanding R7525 memory

IT teams adding memory to a Dell PowerEdge R7525 will find this module validated for that system. Buyers who need unbuffered UDIMMs, non-ECC memory, or a different pin count should look elsewhere because this part is a registered 288-pin DDR4 RDIMM only.

Registered ECC design maintains stability under

Error-correcting code and registered buffering work together to preserve data integrity during sustained server workloads. The 1.2 V operating voltage keeps power draw consistent while the module handles prolonged operation without the signal degradation that can affect unbuffered alternatives.

Questions about this item

Does the Dell PowerEdge R7525 need a specific BIOS version or firmware update before installing this 64GB DDR4 3200 ECC RDIMM?

The module is designed for the PowerEdge R7525 and uses standard DDR4 3200 registered ECC specifications. Check the Dell support site for the latest BIOS to ensure full compatibility with 2Rx4 registered DIMMs.

Can I mix this 64GB 2Rx4 CL22 registered DIMM with existing 32GB 2Rx8 modules in the same R7525?

Mixing different ranks (2Rx4 vs 2Rx8) and capacities in the same channel can prevent the server from posting or force it to run at reduced speed. Dell recommends identical DIMMs per channel for optimal stability.

How do I verify the module is running at 3200 MT/s with ECC active after installation?

Enter the system BIOS or iDRAC interface and confirm the memory speed shows 3200 MT/s, ECC status is enabled, and the total capacity reflects the added 64GB module.
