4GB DDR3 SODIMM for Toshiba Satellite

This 4 GB DDR3-1333 SO-DIMM module is built for the Toshiba Satellite C655D-S5200, C655D-S5202 and C655D-S5302. It uses a 204-pin unbuffered design running at 1.5 V with CL7 timing. The stick adds removable memory to laptops that shipped with 1 GB, 2 GB, 4 GB or 6 GB as standard.

Upgrade from 1 GB or 2 GB factory memory

Replacing a 1 GB or 2 GB stick with this 4 GB module raises the total toward the 8 GB ceiling allowed by a 64-bit operating system. The jump is worth it when the system currently uses a single lower-capacity module and has a free slot. A 32-bit OS will still limit usable memory to 4 GB.

Check socket count and OS before ordering

The platform provides two memory sockets and an AMD E-Series APU at 1.6 GHz. Verify how many slots are already occupied and whether the installed OS is 32-bit or 64-bit. If 4 GB is already present, the recognised total may drop to 3.5 GB or less depending on system allocation.

Questions about this item

Will the 204-pin DDR3 SODIMM fit the memory slot on my Toshiba Satellite C655D-S5200?

Yes, the module is a 204-pin DDR3 SODIMM and the compatible systems list includes the C655D-S5200, C655D-S5202 and C655D-S5302.

What is the correct way to seat the SODIMM so the laptop recognises the full 4 GB?

Insert the stick at roughly a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click; if the BIOS still shows only 3.5 GB, that is a 32-bit OS limitation, not a seating issue.

Does this unbuffered non-ECC module need any firmware update or periodic replacement?

No firmware update is required; the stick is a standard 1.5 V DDR3 part with a limited lifetime warranty from the manufacturer, so it only needs replacement if it fails.
