Computer Memory Solutions 4GB DDR3 1333 SO-DIMM Panasonic Toughbook 19 Mk5 Cf-19

SKU CH-PGC8-SEGJW

A 4 GB DDR3 1333 MHz SO-DIMM module built for the Panasonic Toughbook 19 Mk5 CF-19, delivering CL7 timing at 1.5 V

  • Capacity4GB
  • Type204-Pin DDR3 SO-DIMM
  • SpeedDDR3 1333 (PC3 10600)
  • CAS LatencyCL7
  • Timing7-7-7
  • Voltage1.5V
  • 4GB capacity expands Toughbook 19 Mk5 memory
  • DDR3 1333 speed matches system specification
  • CL7 latency supports responsive operation
  • 204-pin SO-DIMM fits the laptop slot
  • 5V voltage aligns with platform requirement

Targeted Upgrade

This 4GB DDR3 SO-DIMM is built specifically for the Panasonic Toughbook 19 Mk5 Cf-19. It suits field technicians or mobile workers who need to restore or expand system memory in that exact rugged platform. The module arrives new and ready for immediate installation.

Build Integration

The stick uses a standard 204-Pin DDR3 SO-DIMM form factor and runs at 1.5V unbuffered, requiring no special cooling or configuration beyond an empty slot. The Toughbook 19 Mk5 Cf-19 accepts up to 8GB across 2 sockets, so this single 4GB module leaves the second socket free for a matching upgrade later.

Sustained Operation

Rated at DDR3 1333 (PC3 10600) with CL7 7-7-7 timings, the memory maintains its specified latency and bandwidth during extended workloads without a heat spreader. A 32-bit operating system will recognise only 3.5GB or less of the installed capacity, while a 64-bit OS is required to address the full 4GB.

Highlights

Questions about this item

Will the 1.5 V DDR3 1333 SO-DIMM stay stable when the Toughbook 19 Mk5 runs hot under load?

The module is rated for standard 1.5 V operation without a heat spreader; sustained heavy workloads will raise its temperature but it remains within JEDEC limits for DDR3 SO-DIMMs.

How much power does the 4 GB 204-pin kit draw during all-day use?

At 1.5 V and CL7 the stick typically draws only a few watts, so battery impact on the CF-19 is minimal even during continuous operation.

Does the CF-19 Mk5 need a 64-bit OS before this 4 GB stick can be recognised?

A 32-bit OS will still see the module but may report only 3.5 GB or less; a 64-bit OS is required to address the full 4 GB.
