DDR3 SODIMM kit for Panasonic Toughbook 31

This 8 GB kit contains two 4 GB DDR3 1333 MHz SODIMM modules built for Panasonic Toughbook 31 models CF-31GA2CA2M, CF-31GG2EA2M and CF-31GS2EX2M. Each stick is a 204-pin unbuffered non-ECC module running at 1.5 V with CL9 timing. The matched pair is designed for dual-channel operation in the two available memory sockets.

DDR3 1333 MHz speed and 8 GB total capacity

The DDR3 1333 MHz (PC3 10600) interface sets the maximum data rate these modules can deliver. A 32-bit operating system limits usable memory to 4 GB, while a 64-bit operating system allows the full 8 GB. The two SO-DIMM sockets cap total installed memory at 8 GB regardless of larger modules being available.

Verify Toughbook 31 model and OS architecture

Confirm the laptop is one of the three listed CF-31 variants before ordering. Check whether the installed operating system is 32-bit or 64-bit to know if the full 8 GB will be addressable. Ensure both memory slots are free or that existing modules can be removed to make room for the pair.

Questions about this item

Should I buy the 8GB kit or just a single 4GB module for my Toughbook 31?

The kit provides two matched 4GB modules to fill both SODIMM sockets, enabling dual-channel operation and reaching the 8GB maximum supported by a 64-bit OS.

What does the 1333MHz rating mean for everyday performance on a Panasonic Toughbook 31?

The modules run at DDR3-1333 with CL9 timing, delivering the standard memory bandwidth the Toughbook 31 chipset expects for general workloads.

Will these 204-pin DDR3 SODIMMs work in the Toughbook 31's memory slots?

Yes, they are 204-pin DDR3 SO-DIMMs specified for the Cf-31Ga2Ca2M, Cf-31Gg2Ea2M and Cf-31Gs2Ex2M models.
