Compatible Toshiba Satellite Upgrade

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 timings. It is built for the Toshiba Satellite C655-S5507 and L775-S7114 notebooks that accept 204-pin unbuffered memory. The 1.5 V voltage matches the original specification for these models.

Suitable For Single-Channel Notebooks

The two-module kit fills both slots on systems limited to 8 GB maximum capacity across two sockets. It will not suit laptops that require ECC or registered DIMMs. Buyers needing higher density per slot or faster JEDEC speeds should look elsewhere.

1066 MHz CL7 Speed Rating

The decisive specification is the DDR3-1066 (PC3-8500) rating with 7-7-7 latency. Modules at 1333 MHz or with different CAS values may not operate at the intended timings on these platforms.

Questions about this item

Does the 1.5 V DDR3 1066 MHz kit run hot or noisy in a Toshiba Satellite C655-S5507 under all-day load?

These unbuffered SO-DIMMs have no heat spreader and draw standard 1.5 V; they add no fan noise and run at normal notebook temperatures.

What must my Toshiba Satellite L775-S7114 already have for this 2 x 4 GB 204-pin kit to work?

Two free DDR3 SO-DIMM slots and a BIOS that accepts 8 GB total at 1066 MHz CL7.

Will the CL7 1066 MHz modules down-clock reliably beside the original 1333 MHz CL9 sticks in a Satellite L755D-S5109?

Yes — the kit is rated 1066 MHz CL7 and will run at the lower common speed without errors.
