Compatible Fujitsu Lifebook Upgrade

This 4GB SODIMM is built for Fujitsu Lifebook S560/A, T580, T730, T731 and T900 models. It delivers a direct memory upgrade for compatible notebooks using DDR3 technology. The module installs in one of two available expansion sockets.

DDR3 1066 MHz Interface Limit

The DDR3 1066 standard caps transfer rates at PC3 8500 bandwidth. Systems that require faster memory speeds cannot utilise higher frequencies with this module. A 64-bit operating system is necessary to address the full installed capacity.

4GB Single Module Capacity

One 4GB stick occupies a single slot and leaves the second socket free for expansion. If 4GB is installed, the recognised memory may be reduced to 3.5GB or less depending on system configuration. Maximum supported memory is 8GB across both slots.

Questions about this item

Should I choose this single 4 GB stick or look for a 2-stick kit?

This module is sold as a single 4 GB stick; the listed notebooks have two sockets and support up to 8 GB total, so adding a second identical stick later will reach the maximum.

What does the 1066 MHz rating actually deliver in these Fujitsu Lifebook models?

The memory runs at DDR3-1066 (PC3-8500) with CL7 timing at 1.5 V, matching the speed grade the chipset officially supports.

The spec says 204-pin DDR3 SO-DIMM — does that guarantee it will work in my Lifebook T730?

Yes, the 204-pin DDR3 SO-DIMM form factor is the correct physical and electrical interface for all listed Lifebook models including the T730.
