Panasonic Toughbook C2 Mk1 memory upgrade

This 4 GB SODIMM is built specifically for the Panasonic Toughbook C2 Mk1 CF-C2 series. It delivers a direct-fit DDR3L module that matches the factory slot and voltage requirements. The single-stick kit simplifies installation for field service or depot repair. No configuration changes are needed on supported units.

Suits technicians restoring or expanding a C2 Mk1

Technicians who need a guaranteed-compatible 4 GB stick for the listed Toughbook models will find this part validated by the supplier. Buyers who want more storage capacity or a different form factor such as a 2.5-inch drive should look elsewhere. The module does not support ECC or registered operation. Systems requiring those features cannot use this stick.

DDR3L 1600 CL11 at 1.35 V decides fit

The module runs at DDR3L 1600 (PC3L 12800) with CL11 11-11-11 timing at 1.35 V. This exact voltage and speed combination is what the C2 Mk1 memory controller expects. A different voltage or DDR generation will not seat or operate correctly. Verify the target laptop model matches the compatibility list before ordering.

Questions about this item

Should I pick the 4 GB stick or add a second one to reach the 6 or 8 GB maximum shown for the Toughbook C2 Mk1?

The module is a single 4 GB stick; the system accepts up to 6 or 8 GB total, so adding a second identical SODIMM will fill the expansion slot and raise capacity toward that ceiling.

What does the 1600 MHz / PC3L 12800 rating deliver once the SODIMM is seated in the C2 Mk1?

At 1.35 V the stick runs at DDR3L 1600 with CL11 11-11-11 timings, giving the peak bandwidth the platform’s memory controller allows for this generation.

The spec says 204-pin DDR3L — does that limit speed or voltage compared with standard DDR3?

The 204-pin SO-DIMM form factor carries DDR3L at 1.35 V and 1600 MHz; the lower voltage is the only practical difference from 1.5 V DDR3 at the same frequency.
