Axiom 647901-S21-AX 16 GB DDR3 1333 MHz ECC Registered DIMM 1.35 V memory upgrade

SKU CH-CBQK-3FEG9 MPN 647901-S21-AX

A 16 GB DDR3 registered ECC DIMM running at 1333 MHz and 1.35 V for compatible systems

  • 16 GB DDR3 capacity supports demanding server workloads
  • 35 V low-voltage operation reduces power draw and heat
  • ECC registered design detects and corrects data errors automatically
  • 1333 MHz DDR3-1333/PC3-10600 speed matches qualified system specs
  • 5 mil standard DIMM thickness fits approved server slots

Axiom 16 GB DDR3 Registered ECC DIMM

This Axiom module is a 16 GB DDR3 registered ECC DIMM built for servers and workstations that require error-correcting memory. It operates at 1333 MHz with a low 1.35 V supply and conforms to the PC3-10600 standard. The dual-rank design fits standard DIMM slots in qualified platforms.

Registered ECC signal processing

The registered ECC signal processing is the specification that determines compatibility; only systems designed for registered ECC DDR3 DIMMs can use this module. Unbuffered or non-ECC platforms will not accept it. Verify the motherboard or server documentation before purchase.

16 GB capacity for memory-intensive workloads

Sixteen gigabytes per module provides substantial headroom for virtualisation, database caching and large dataset processing in compatible systems. Capacity limits are reached when the platform's maximum supported memory per slot or total populated slots is exceeded, or when application demand surpasses the installed amount.

Questions about this item

What does 16 GB at 1333 MHz mean for a live server workload?

The module delivers 16 GB of DDR3 capacity at 1333 MHz with ECC and registered signal processing, giving the memory controller corrected data and reduced electrical load per DIMM slot.

How does the PC3-10600 rating limit real-world throughput?

PC3-10600 defines the DDR3-1333 data rate; the memory bus will not exceed that frequency, so peak bandwidth is set by the 1333 MHz clock and the 64-bit DIMM width.

Will the 157.5 mil thickness fit a standard DIMM slot?

At 157.5 mil (approximately 4 mm) the module matches the standard DIMM card thickness, so it seats in any DDR3 DIMM socket keyed for registered ECC memory.
