DELL AA810826 16GB DDR4 ECC Registered DIMM 3200MHz

SKU CH-CK7J-0B3QH MPN AA810826

A 16 GB DDR4 ECC registered DIMM running at 3200 MHz for compatible Dell PowerEdge servers

  • TypeRAM Module
  • 16 GB capacity supports large server workloads
  • DDR4 3200 MHz speed matches DDR4-3200/PC4-25600 standard
  • ECC registered design protects data integrity in servers
  • 288-pin DIMM fits compatible Dell PowerEdge systems
  • 20 V operation reduces power draw per module

Dell 16GB DDR4 ECC Registered DIMM

This module adds 16 GB of DDR4 server memory to compatible Dell PowerEdge systems. It operates at 3200 MHz with a 1.20 V supply and includes error-correcting code plus registered signal processing for data integrity. The 288-pin DIMM form factor fits standard server memory slots. It is built for administrators upgrading or repairing supported Dell rack and tower servers.

Capacity and headroom for virtualised workloads

A single 16 GB stick suits moderate virtualisation, database caching and application hosting where ECC protection is required. Registered buffering allows larger total memory configurations than unbuffered modules can achieve. Systems needing more than the per-slot maximum or higher total capacity will require additional modules or higher-density DIMMs not covered by this part.

Registered ECC DDR4-3200/PC4-25600 standard

The module conforms to the DDR4-3200/PC4-25600 specification with ECC and registered signalling, which determines compatibility with the memory controller. Only Dell PowerEdge models listed in the manufacturer compatibility matrix — including R640, R740, R740XD, R7515, R7525, R6515, R6525, R840, R940, R940xa, T440, T640, M640, MX740C, MX840C, C4140, C6420, C6525, FC430, FC640, FC830, NX3240, R440, R540 — support this part. Buyers whose servers are not on that list cannot use this DIMM.

Questions about this item

Will the 16GB DDR4 3200MHz ECC Registered DIMM run with slower DDR4 modules already in my PowerEdge R740?

The module is rated for DDR4-3200/PC4-25600 at 1.20V; the server memory controller will clock all installed DIMMs to the lowest common speed, so mixing with slower DDR4 works but the faster module will downclock.

How can I confirm the AA810826 is detected and running with ECC active after installation?

Enter the system BIOS or iDRAC interface on the PowerEdge server; both will show 16GB per module, 3200MHz operating speed, and ECC status as enabled for each populated slot.

Does the AA810826 box include a heatsink or any installation tools, or must I buy them separately?

The package contains only the 288-pin DIMM itself; no heatsink, screwdriver, or anti-static wrist strap is supplied, so source any required tools separately.
