Targeted laptop upgrade

This 4GB DDR3 SODIMM module is built for Toshiba Satellite A505 series notebooks listed in the compatibility data. It installs in a 204-pin slot and runs at 1066MHz with CL7 timing at 1.5V.

Suitable for single-slot expansion

The unbuffered non-ECC design matches the factory specification for the supported Satellite models. Buyers needing ECC registered memory, a different DDR generation, a heat spreader, or a larger capacity kit should look elsewhere.

1066MHz DDR3 speed rating

The module operates at PC3-8500 1066MHz with 7-7-7 latency. Confirm the laptop accepts this exact speed before purchase because a mismatched frequency will prevent the system from booting.

Questions about this item

Does the 204-pin SODIMM fit the memory slot on a Toshiba Satellite A505-S6004?

Yes, the module is a 204-pin DDR3 SO-DIMM built for the Satellite A505-S6004, A505-S6005, A505-S6007 and the other listed A505 models.

What is the common mistake when installing this 204-pin DDR3 SO-DIMM in a Satellite A505?

Inserting the stick at the wrong angle or not pressing firmly until both side clips click; the notch must align with the slot key before you seat it.

Will this 4 GB DDR3 1066 MHz module need any firmware updates or battery replacement over time?

No firmware or battery is involved; the SO-DIMM is a passive component. If a memory error appears later, reseat the stick or test with a known-good module.
