Axiom P1N55AA-AX 16GB DDR4-2133 SODIMM server RAM

SKU CH-GK53-CPCYF MPN P1N55AA-AX

16 GB DDR4-2133 SODIMM with CL15 latency and 1.20 V operation for notebooks and desktops

  • 16 GB capacity runs memory-hungry programs simultaneously
  • DDR4-2133 speed delivers responsive application loads
  • CL15 latency and 1.20 V reduce power consumption by 20 %
  • 260-pin SODIMM form factor fits notebook and desktop systems
  • Axiom compatibility assurance backs enterprise-grade reliability

16 GB DDR4-2133 SODIMM module

This 16 GB DDR4 SODIMM runs at 2133 MHz with a CL15 latency and 1.20 V operating voltage. The 260-pin form factor fits standard notebook and desktop memory slots. It is sold new and carries Axiom compatibility assurance for HP part numbers P1N55AA and P1N55AT.

Suits DDR4 SODIMM slots requiring 2133 MHz CL15

Builders upgrading compatible HP notebooks or small-form-factor desktops can use this module to reach 16 GB capacity. Systems limited to DDR3, higher-speed DDR4, or DIMM slots cannot accept this part. Buyers needing ECC, registered, or lower-latency memory should look elsewhere.

2133 MHz DDR4 speed rating

The module operates at 2133 MHz (PC4-17000) with CL15 timing at 1.20 V. This single speed specification determines whether the memory matches the platform's supported data rate and voltage.

Questions about this item

How much power does the 16GB DDR4-2133 SODIMM draw at 1.20 V during continuous operation?

The module operates at 1.20 V, which is 20% lower than DDR3, reducing heat output and cooling demand during all-day use.

What slot type and pin count must my system provide for this 260-pin SoDIMM?

Your laptop or desktop needs a DDR4 SODIMM socket with 260 pins; the module is keyed for PC4-17000 and will not fit DDR3 or 204-pin slots.

Will this CL15 2133 MHz stick run reliably alongside existing DDR3 memory in the same machine?

No, DDR4 and DDR3 use different voltages, pin layouts and signalling, so they cannot be mixed in the same system.
