Compatible DDR2 upgrade for Tecra M7

This 2 GB DDR2 SO-DIMM is built to match the memory slots of the Toshiba Tecra M7 series, including the GH1, 141, S7311, S7331 and SP8013 models. It installs as a single 200-pin module running at 667 MHz with CL5 timing. The unbuffered, non-ECC design suits standard notebook workloads.

Low-voltage operation at 1.8 V

The module draws power at the standard DDR2 1.8 V level, keeping heat output modest inside the Tecra chassis. With no heat spreader and no active cooling, it relies on the notebook's existing airflow. The CL5 5-5-5 timing delivers the rated PC2-5300 bandwidth without extra voltage.

Single-stick kit with lifetime guarantee

The package contains one memory stick only, so capacity scales by adding identical modules if a second slot is free. Computer Memory Solutions backs compatibility with a limited lifetime warranty when purchased directly, and the manufacturer highlights that appearance may vary from the reference photo.

Questions about this item

How do I install this 200-pin DDR2 SO-DIMM in my Tecra M7, and which step causes the most problems?

Power off and unplug the laptop, remove the battery, open the memory door, insert the module at a 30-degree angle until the gold contacts disappear, then press down until the side clips click — the step most people miss is pushing firmly enough to engage both clips.

What maintenance or replacement will this 2GB DDR2 module need later?

No scheduled maintenance is required; if errors appear, run a memory test and replace the stick — the limited lifetime warranty from Computer Memory Solutions covers defects when purchased directly from them.

What limit appears first when this CL5 1.8V DDR2 memory runs under sustained load?

The 667 MHz speed and CL5 latency set the bandwidth ceiling; sustained heavy workloads will hit that throughput limit before voltage or thermal constraints become an issue.
