System-specific DDR3 SO-DIMM kit

This 8GB kit contains two 4GB unbuffered SO-DIMM modules built to the PC3-8500 standard. It targets owners of the listed Toshiba Satellite models who need a matched pair for dual-channel operation.

204-pin layout and 1.5V operation

The modules use a standard 204-pin edge connector and run at 1.5 volts with CL7 timing. No heat spreader is fitted, so they sit low in tight notebook slots and draw only the power the platform expects.

Replaces factory 4GB or mismatched sticks

Moving from a single 4GB module to this 8GB pair enables full dual-channel bandwidth and supports a 64-bit operating system. The upgrade is worthwhile when the current configuration leaves one slot empty or mixes speeds.
