Compatible Toshiba Satellite upgrade

This 4GB DDR3 SO-DIMM is built for the Toshiba Satellite C655D-S5508, C655-S5541 and C655-S5547. It uses a 204-pin unbuffered layout with a 2Rx8 rank structure. The module installs directly into the factory memory slots without configuration changes.

Low voltage CL7 timing

Operating at 1.5V with a CAS latency of 7 and 7-7-7 timing, the stick runs at DDR3 1333 (PC3 10600) speed. The unbuffered design keeps power draw modest during typical workloads. No heat spreader is fitted, so airflow in the laptop chassis handles thermal dissipation.

Major brand chipset 2Rx8 layout

The module uses a major brand chipset in a 256x8 organisation across 16 chips. It fits the two sockets available in the compatible models, which support a maximum of 8GB. Buyers who want more capacity will need a second module. Systems requiring ECC or registered memory cannot use this stick.

商品問答

How do I install the 204-pin DDR3 SO-DIMM in my Toshiba Satellite C655-S5541, and what step is often missed?

Power off the laptop, remove the battery, open the memory compartment, align the notch on the 204-pin module with the slot key, press firmly until both side clips click, then reinstall the battery before booting.

What maintenance or replacement will the 4GB 2Rx8 CL7 module need over its lifetime?

No scheduled maintenance is required; the unbuffered non-ECC stick has no moving parts, so replacement is only necessary if a memory test reports errors or you upgrade to the 8 GB maximum supported by the two sockets.

What limit appears first when the 1.5 V DDR3-1333 CL7 memory runs under sustained load?

The CAS 7 timing at 1333 MHz sets the latency floor; thermal throttling is unlikely without a heat spreader, so the fixed latency and 4 GB capacity are the primary constraints during prolonged use.
