Axiom 713985-B21-AX 16 GB DDR3-1600 ECC Registered server RAM

SKU CH-A55D-3RCWQ MPN 713985-B21-AX

16 GB DDR3-1600 ECC registered DIMM runs at 1.35 V for low-voltage server memory upgrades

  • Rated speedDDR3 SDRAM
  • ECC supportECC
  • Buffer typeRegistered
  • 16 GB capacity for high-density server workloads
  • 1600 MHz DDR3 speed for responsive data throughput
  • ECC registered design protects data integrity
  • 35 V low-voltage operation reduces power draw
  • DIMM form factor fits standard server slots

Server memory upgrade for registered ECC platforms

This 16 GB DDR3-1600 module targets administrators who need to expand capacity on servers that require registered ECC DIMMs. It operates at 1.35 V and conforms to the PC3-12800 standard for compatible systems. The dual-rank design fits standard DIMM slots in qualified platforms.

Installation notes for registered DIMMs

The module installs like any standard DIMM but must go into slots that support registered signal processing and ECC. Mixing registered with unbuffered memory will prevent the system from posting. Verify the server's qualified-vendor list before adding this part to avoid firmware-level incompatibilities.

Capacity and headroom for DDR3-1600 workloads

Sixteen gigabytes per module suits virtualization hosts, database nodes and compute clusters that benefit from ECC protection at DDR3-1600 speeds. Workloads that exceed the registered controller's bandwidth or require higher densities will need platforms that support faster DDR generations or larger registered modules.

Questions about this item

How can I verify the 16 GB DDR3-1600 module is running at 1600 MHz with ECC active after installation?

Enter the server BIOS or UEFI and confirm the memory speed reads 1600 MHz, the voltage shows 1.35 V, and ECC is reported as enabled for the 16 GB DIMM.

What ships with the 713985-B21-AX module and what must be sourced separately?

The box contains the single 16 GB PC3L-12800 registered ECC DIMM; any additional DIMMs, memory risers or cooling shrouds required by your server chassis are sold separately.

When should I choose this 16 GB dual-rank 1.35 V registered ECC DDR3 DIMM over other capacities?

Select this 16 GB module when your server requires low-voltage PC3L-12800 registered ECC memory and the configuration calls for dual-rank 1600 MHz DIMMs to fill the supported slots.
