  • ECC registered design protects data integrity
  • 5 mil DIMM profile fits standard desktop slots

System-specific 16 GB DDR3 module

The Axiom 713985-S21-AX is a 16 GB DDR3 registered DIMM built for desktop systems that require ECC error checking. It operates at 1600 MHz with a low 1.35 V voltage and conforms to the PC3-12800 standard. The dual-rank design uses tier-one components for mission-critical stability.

Verify registered ECC support and voltage

Before ordering, confirm that your motherboard and processor support registered DDR3 modules with ECC functionality. The module requires a 1.35 V memory voltage slot and the PC3-12800 speed rating. Systems limited to unbuffered non-ECC memory will not accept this DIMM.

Low-voltage operation reduces heat

Running at 1.35 V lowers power draw compared to standard 1.5 V DDR3, which helps keep module temperatures modest under normal workloads. The registered buffer adds slight latency but improves signal integrity in populated slots. No active cooling is required for typical desktop use.

Questions about this item

What does the 713985-S21-AX kit include and is anything extra needed for installation?

The package contains one 16 GB DDR3 DIMM module. No additional components are required beyond a compatible desktop motherboard slot.

How do I decide between the registered ECC version and a standard unbuffered module?

Choose this registered ECC module if your workstation or server board requires error correction and registered signalling; otherwise select a standard unbuffered kit.

What does the 1600 MHz rating mean for actual system performance?

The module runs at 1600 MHz (PC3-12800) with 1.35 V low-voltage operation, delivering the rated bandwidth when the platform supports DDR3-1600.
