Axiom

Axiom 4X70Q27989-AX 16 GB DDR4-2400 ECC SODIMM 260-pin CL17 1.2 V

SKU CH-MFAN-EXQFA

16 GB DDR4-2400 ECC SODIMM with 260 pins, CL17 timing and 1.2 V operation

  • 16 GB DDR4-2400 capacity for demanding workloads
  • ECC protection detects and corrects memory errors
  • 260-pin SODIMM form factor fits compatible laptops
  • CL17 latency at 1.2 V for efficient operation
  • PC4-19200 bandwidth supports high-speed data transfer

Purpose-built upgrade

This 16 GB DDR4 SODIMM targets laptops and small-form-factor systems that require ECC protection. Unbuffered operation keeps latency low for everyday workloads while the error-correcting code guards data integrity in long-running tasks.

Interface ceiling

The module runs at 2400 MHz with a PC4-19200 transfer rate and CL17 timing. Bandwidth and latency are fixed by the DDR4 standard at this speed class, so performance will not exceed the platform’s native memory controller limits.

Daily fit

A 260-pin edge connector slots directly into standard SODIMM sockets without adapters. The 1.2 V operating voltage matches mainstream mobile platforms, reducing heat output and preserving battery life during extended sessions.
