Targeted notebook upgrade

This 4GB DDR3 SODIMM module is built for Fujitsu-Siemens Lifebook T1010, T2020, T5010 and T901 models. It suits owners of those specific notebooks who need to replace a failed stick or add capacity to an open slot. Buyers with other laptop families or desktop systems cannot use this part.

Speed and pin count

The module runs at DDR3 1066 (PC3 8500) with CL7 7-7-7 timing on a 204-pin SO-DIMM interface at 1.5V. Only notebooks that accept DDR3 1066 unbuffered non-ECC memory in a 204-pin slot will recognise the full 4GB. Systems limited to slower DDR3 speeds or different pin layouts will not be compatible.

Single-stick simplicity

The package contains one memory stick with no heat spreader, cables, software or adapters. Installation is a direct swap into an available SODIMM socket. No configuration utilities or driver discs are included or required.

Questions about this item

What does DDR3 1066 mean for everyday use in a Fujitsu-Siemens Lifebook?

The module runs at 1066 MHz with CL7 timing, giving the supported Lifebook models the rated PC3 8500 bandwidth for standard office and web tasks.

How does the PC3 8500 rating relate to the SO-DIMM slot in these laptops?

PC3 8500 is the DDR3 1066 standard; the 204-pin SO-DIMM fits the two expansion sockets in the T1010, T2020, T5010 and T901.

Will the 204-pin stick fit the Lifebook T1010, T2020, T5010 or T901 without modification?

Yes, the 204-pin DDR3 SO-DIMM matches the two SODIMM slots in each listed model; no heat spreader means it clears the standard retention clips.
