System-specific DDR3 SODIMM

This 4 GB DDR3-1333 module is built for Toshiba Satellite C855-S5241, C855-S5245 and C855-S5247 notebooks. It installs in a 204-pin SO-DIMM slot and operates at 1.5 V without ECC or buffering. The stick uses a 2Rx8 rank layout with CL7 timing.

Speed grade decides fit

The module runs at PC3-10600 (1333 MT/s) with 7-7-7 latency. Supplier data also lists a DDR3-12800 (1600 MT/s) rating; the laptop’s memory controller will set the actual clock. If the system requires a different speed grade, this part will not match.

Two-slot limit shapes the upgrade

The compatible laptops have two SO-DIMM sockets and support up to 8 GB total. This single 4 GB stick fills one slot and leaves the second free for another module. Buyers who want more than 8 GB or who need ECC memory cannot use this kit.

Questions about this item

Will the 1333 MHz speed run at that rate in my Toshiba Satellite C855-S5241?

The module is rated DDR3-1333 (PC3-10600) and will operate at that speed if the laptop’s memory controller supports it; otherwise it will downclock to the highest speed the system allows.

Does the 204-pin DDR3 SO-DIMM interface match the slot in the C855-S5245?

Yes, the 204-pin DDR3 SO-DIMM form factor is the standard used by the Satellite C855 series, so the module fits the memory slot directly.

What physical space does the 1.5 V unbuffered stick need inside the C855-S5247 chassis?

It is a standard low-profile SO-DIMM with no heat spreader, requiring only an empty 204-pin slot and the normal clearance found in the Satellite C855 laptops.
