Compatible Toughbook 54 CF-54 memory

This 8GB DDR4 SODIMM module is built specifically for the Panasonic Toughbook 54 CF-54 series. It targets users upgrading compatible CF-54G, CF-54J or CF-54mk3 models that require 260-pin DDR4 memory. The single stick installs directly into one of the system's two slots. Buyers needing ECC support or registered memory should look elsewhere.

Speed and timing decide fit

The module runs at DDR4 2400 (PC4 19200) with CL17 latency and 17-17-17 timing at 1.2V. These exact electrical parameters must match the laptop's memory controller specification. The 2Rx8 rank organisation and unbuffered, non-ECC design are fixed characteristics. A different speed grade or latency will not work correctly in this platform.

Low voltage keeps thermals simple

Operating at the standard DDR4 voltage of 1.2V, the stick draws minimal power and generates little heat during normal workloads. No heat spreader is fitted, relying on the chassis airflow of the Toughbook 54 for passive cooling. The memory operates silently with no moving parts or active cooling required.

Questions about this item

What does the 2400 MHz DDR4 speed mean once the module is installed in a Toughbook 54?

The module will run at up to 2400 MHz if the system supports that frequency; otherwise it down-clocks to the highest speed the platform allows.

How does the 260-pin DDR4 SO-DIMM interface limit performance in practice?

It caps the memory to DDR4 electrical and mechanical standards, so the stick cannot exceed the platform's maximum supported DDR4 rate.

What physical space is needed to fit this SODIMM into the CF-54?

A single 260-pin DDR4 SO-DIMM slot; the laptop has two such sockets and supports up to 32 GB total.
