Axiom 16GB DDR3 ECC Registered module

This Axiom A7187318-AX module delivers 16GB of DDR3 1866 server memory with ECC and registered signal processing. It operates at 1.50V with a CAS latency of CL13 and uses the standard 240-pin DIMM form factor. The part is listed as compatible with multiple Dell PowerEdge and Precision Workstation models.

Suited for admins upgrading listed Dell servers

Administrators maintaining Dell PowerEdge R610, R620, R715, R720, R720xd, M620, T620 or Precision T3610 systems can use this module to expand capacity. It is not intended for desktop boards that require unbuffered non-ECC memory or for platforms that only support newer DDR generations.

No bundled accessories or software included

The module ships as a standalone memory component without additional cables, brackets or software utilities. Installation relies on the server's existing DIMM slots and BIOS recognition of the registered ECC specification.

Questions about this item

My server only takes 240-pin DDR3 modules — will this A7187318-AX stick fit?

Yes, the module uses the 240-pin DDR3 form factor that matches slots wired for DDR3 1866 (PC3 14900) memory.

Can I mix this 16 GB CL13 registered ECC DIMM with the original 8 GB registered ECC sticks already in my PowerEdge R620?

The R620 supports mixed capacities of registered ECC DDR3; the system will run all modules at the lowest common speed and latency.

How do I confirm the module is running at 1866 MHz with ECC active after installation?

Check the BIOS memory information screen or run dmidecode — it should report 1866 MT/s, CL13 timings, 1.50 V and ECC type registered.
