Compatible DDR3 SO-DIMM upgrade

This 4 GB DDR3 module runs at 1333 MHz with CL7 timings and 1.5 V unbuffered operation. The 204-pin SO-DIMM form factor fits the listed Toshiba Satellite notebooks. A single stick is supplied in the package.

Buyers matching the specified Satellite models

Owners of Toshiba Satellite P775-S7320, P775-S7365 or P775D-03C can install this module directly. Systems requiring ECC, registered DIMMs, a different pin count or a higher voltage should not use this part.

2Rx8 rank configuration

The memory is organised as 2Rx8 using major-brand chips without a heat spreader. This rank layout must match the platform's memory-controller expectations for stable operation.

Questions about this item

Should I pick the 4 GB CL7 stick or the 1600 MHz variant listed in the highlights?

The module supplied is a single 4 GB DDR3 SODIMM rated at 1333 MHz with CL7 timings; the 1600 MHz figure appears only in the manufacturer highlights and does not describe the shipped part.

Will the CL7 latency at 1333 MHz feel faster than a standard CL9 module in my Satellite P775?

At the same 1333 MHz bus speed, CL7 reduces the cycle wait from nine to seven cycles, shaving a few nanoseconds per access — measurable in benchmarks but barely noticeable in everyday tasks.

Does the 204-pin DDR3 SO-DIMM interface limit the usable speed to 1333 MHz on my laptop?

Yes, the SO-DIMM socket and the chipset in the compatible Satellite models cap the memory bus at DDR3-1333 (PC3-10600), so faster modules would simply down-clock.
