Compatible upgrade for Fujitsu Lifebook tablets

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 timing. It is built specifically for the Fujitsu-Siemens Lifebook T901, T731 and T580 tablet PCs. The unbuffered, non-ECC design matches the original memory specification for these systems.

Low-voltage operation at 1.5 V

Each module runs at the standard DDR3 voltage of 1.5 V without a heat spreader. The 2Rx8 rank organisation and major-brand chipset keep power draw modest during normal workloads. Passive cooling is sufficient for the thin tablet chassis these modules are designed to occupy.

Two-slot kit fills the maximum expansion

The T901, T731 and T580 each provide two SO-DIMM sockets supporting up to 8 GB total. This kit occupies both slots, delivering the full supported capacity in a single purchase. No additional modules are required and no slots remain free for further upgrades.

Questions about this item

How do I install the 204-pin SODIMM modules in a Fujitsu T901?

Power off the tablet, remove the battery, open the memory cover, insert each stick at an angle until the gold contacts disappear, then press down until the side clips lock both 4GB modules in place.

What maintenance or replacement will the CL7 DDR3 kit need later?

No routine maintenance is required; if a module fails, the limited lifetime warranty from Computer Memory Solutions covers replacement of the 2Rx8 sticks.

What limit appears first under sustained load on the 1.5V PC3-8500 memory?

The 1066 MHz speed and CL7 latency set the throughput ceiling; thermal throttling may occur before bandwidth saturates because the modules have no heat spreader.
