2GB DDR2 SODIMM for Satellite A135

This 2GB DDR2-667 SODIMM is built specifically for Toshiba Satellite A135-S4427, A135-S4437 and A135-S4447 notebooks. It targets owners of those models who need a straightforward memory increase without guessing at compatibility. The module arrives new and carries a lifetime warranty from Computer Memory Solutions.

200-pin unbuffered layout fits factory slots

The stick uses a standard 200-pin SO-DIMM edge connector and runs at 1.8V with CL5 5-5-5 timing. No heat spreader is fitted, so it slips into the existing socket without clearance issues. Unbuffered, non-ECC organisation matches the original factory specification for these Satellite chassis.

Replaces a single 64MB module to reach 4GB max

Each laptop accepts two SODIMMs and supports a maximum of 4GB total. Installing this 2GB module in one slot doubles typical factory fitted capacity and leaves the second socket free for a matching stick later. The upgrade is worthwhile when the system still runs a single low-capacity module and the user wants more headroom for period applications.

Questions about this item

What DDR2 speed does this 200-pin SODIMM run at and what bandwidth does that limit me to?

The module operates at 667 MHz, which is the PC2-5300 standard, so the peak transfer rate is capped at 5300 MB/s.

Will this 200-pin SODIMM fit the two memory sockets in my Toshiba Satellite A135-S4427, A135-S4437 or A135-S4447?

Yes, it matches the 200-pin DDR2 SO-DIMM form factor used by those models, and the system board provides two sockets for upgrade.

How do I install the stick and what is the common mistake to avoid?

Power off, unplug, remove the battery, open the memory door, insert the module at about 30 degrees until the gold edge disappears, then press down until both side clips click; the frequent error is stopping before the clips engage fully.
