System-specific SODIMM for Satellite notebooks

This 4 GB DDR3 module is built to the exact electrical and mechanical spec of the Toshiba Satellite L875D-S7210 and P845-S4200. It installs in a single 204-pin slot and restores factory memory performance without configuration changes. Buyers who need ECC, registered buffering or capacities beyond 8 GB total cannot use this part.

CL11 timing at 1.5 V with no heat spreader

The stick runs at standard DDR3-1600 voltage and CAS latency 11-11-11, drawing minimal power and producing no audible noise in normal operation. Unbuffered 2Rx8 organisation keeps signal loading low for the platform's two-slot topology. Systems that require 1.35 V low-voltage modules or active cooling on memory will not be compatible.

Direct replacement for a 2 GB or 4 GB factory stick

Upgrading from the original 4 GB maximum to this 4 GB module fills one slot and enables dual-channel operation when paired with an identical stick. The jump is worthwhile when the current configuration leaves one slot empty or runs a single 2 GB module. Machines already populated with two 4 GB sticks gain no capacity benefit from this part.

Questions about this item

How do I install this 204-pin DDR3 SODIMM in my Toshiba Satellite, and which step is often missed?

Power off, unplug, remove the battery, open the memory access panel, align the notch on the module with the slot key, press firmly until the side clips click, then replace the panel and battery before powering on.

What maintenance or replacement will this 4GB DDR3 1600MHz module need later?

No scheduled maintenance is required; if a fault appears, the module carries a limited lifetime warranty from Computer Memory Solutions for direct replacement.

What limit appears first when this CL11 1.5V memory runs under sustained load?

The system maximum of 8GB across two slots is reached before the module hits its own speed or voltage ceiling.
