Targeted Upgrade Kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Toshiba Satellite C655D-S5515 and C655D-S5511 notebooks. It runs at 1066 MHz with CL7 timing and 1.5 V unbuffered operation. The 204-pin form factor matches the factory slots exactly.

Replacing Factory Modules

The kit replaces the original memory when the system shipped with less than 8 GB or when existing sticks have failed. Moving to the full 8 GB supported by the platform is worthwhile when multitasking feels slow or when the current total is below the two-socket maximum. Each socket accepts up to 4 GB.

Pre-Installation Checks

Confirm the laptop model number matches C655D-S5515 or C655D-S5511 before ordering. Verify the board has two SO-DIMM slots free for the 2 x 4 GB configuration. Ensure the BIOS recognises DDR3 1066 modules without a voltage mismatch.

Questions about this item

What slot type does the 204-pin DDR3 SO-DIMM kit need in the Toshiba Satellite C655D-S5515?

The laptop uses two 204-pin DDR3 SO-DIMM slots; this kit fills both with matched 4GB modules.

Which step is often missed when seating the 204-pin modules in the C655D-S5511?

Insert each stick at the correct angle then press firmly until the side clips click — partial seating causes no-boot or single-channel operation.

When should the 1.5 V DDR3 1066 CL7 pair be swapped out?

Replace the kit if the system fails memory diagnostics, shows random crashes, or when upgrading beyond the 8 GB maximum supported by the two sockets.
