Axiom

Axiom T7B78AA-AX 16 GB DDR4 SO-DIMM 260-Pin 2133 MHz CL15 1.2 V Unbuffered Non-ECC Server RAM

SKU CH-QYJE-KGYMM MPN T7B78AA-AX

A 16 GB DDR4 SO-DIMM running at 2133 MHz with CL15 latency for compatible HP EliteBook and ZBook models

  • 16 GB capacity runs memory-hungry programs simultaneously
  • 2133 MHz speed with CL15 latency handles heavy applications smoothly
  • DDR4 technology provides 100% faster data rates over DDR3
  • 20% lower power consumption at 1.2 V reduces cooling demands
  • Unbuffered non-ECC SO-DIMM fits HP EliteBook and ZBook G3 models

Target systems

This 16 GB DDR4 SO-DIMM is built for HP EliteBook 840 G3, 850 G3 and ZBook 15 G3, 15U G3, 17 G3, Studio G3 mobile workstations. It suits IT teams upgrading fleet laptops that need reliable, unbuffered non-ECC memory for everyday workloads.

Before ordering

Confirm the notebook uses 260-pin DDR4 slots and accepts 1.2 V modules running at 2133 MHz with CL15 timing. The board must support unbuffered non-ECC memory; registered or ECC variants will not work in these platforms.

Upgrade context

The module replaces 8 GB or smaller DDR4 sticks or legacy DDR3 SO-DIMMs where the platform allows DDR4 migration. The jump is worthwhile when multitasking heavy applications or running virtual machines that exceed current memory capacity.

Questions about this item

Does the Axiom T7B78AA-AX module ship as a single 16 GB stick or do I need to buy a second one for dual-channel?

The module is a single 16 GB SO-DIMM; add a second identical stick if your laptop supports dual-channel operation.

Should I choose this 2133 MHz CL15 version or a faster DDR4 module for my EliteBook 840 G3?

The EliteBook 840 G3 platform is specified for 2133 MHz memory; faster modules will downclock to this speed.

Will the advertised 2133 MHz speed actually run at that frequency once installed in a ZBook 15 G3?

Yes, the ZBook 15 G3 supports DDR4-2133 natively so the module will operate at its rated 2133 MHz CL15 timing.
