4GB DDR3-1066 SODIMM for ThinkPad X200

This 4GB DDR3-1066 CL7 module is built for Lenovo ThinkPad X200 models 2024, 7454, 7455, 7457 and 7458. It uses a 204-pin SO-DIMM form factor and runs at 1.5V without ECC or buffering.

Suits single-slot upgrades on listed X200 units

Owners of the specified ThinkPad X200 variants can add this stick to a free slot or replace an existing module. Builders working on other laptops, desktops or newer ThinkPad generations cannot use this DDR3 SO-DIMM.

PC3-8500 speed rating sets the bandwidth ceiling

The module operates at 1066 MHz with 7-7-7 timings, delivering the PC3-8500 data rate. Systems that require faster DDR3 speeds or a different voltage will not reach their rated performance with this part.

Questions about this item

Will the 204-pin DDR3 SODIMM need any firmware updates or periodic reseating after installation?

No firmware is required; the module is a standard 1.5 V unbuffered DDR3 stick that simply seats in the slot and runs without further maintenance.

What electrical or thermal limit appears first when the CL7 1066 MHz module runs continuously in a ThinkPad X200?

The fixed 1.5 V operating voltage and lack of a heat spreader mean the memory controller’s voltage ceiling is reached before any thermal throttle can occur.

How much heat and fan noise does the 4 GB 2Rx8 stick add during all-day use?

Without a heat spreader the module relies on chassis airflow, so it contributes minimal extra heat and no audible noise beyond the system’s existing cooling.
