System-Specific DDR3L SODIMM for Sony Vaio
This 4 GB DDR3L SODIMM is built for the Sony Vaio VPCEB42EG, VPCEA43FB, VPCEA43FX and VPCEA44FX laptops. It fits the 204-pin slot and runs at 1.35 V, matching the factory voltage requirement. The module is unbuffered, non-ECC and uses a single-rank 1Rx8 organisation with Major Brand Chipset components.
Sustained-load behaviour with CL11 timing
At 1600 MHz the stick operates at PC3L 12800 bandwidth with 11-11-11 timings. CAS latency 11 keeps access consistent during long sessions such as video encoding or large spreadsheet recalculation. The single 4 GB rank feeds the controller without interleaving delays, so throughput remains stable once caches are warm.
Thermals, noise and power draw in normal use
Running at the standard 1.35 V keeps power draw low and eliminates the need for a heat spreader. The module produces no audible noise and adds minimal heat to the laptop chassis. The platform supports a maximum of 8 GB across two sockets, so a second identical stick can be added later if the 64-bit operating system is present.

Questions about this item
Will the 1.35 V DDR3L module run hotter or draw more power than the original memory during long sessions?
The module operates at the standard 1.35 V DDR3L voltage, so power draw and heat output match the factory specification for the listed Sony Vaio models.
Does my Vaio need a 64-bit operating system to recognise the full 4 GB capacity of this SODIMM?
The system supports up to 8 GB across two sockets; a 64-bit OS is required only when the total installed memory exceeds 4 GB.
Can this CL11 1600 MHz stick be paired with the factory CL11 module already in the second slot?
Both the new and original modules share CL11 11-11-11 timing and 1.35 V voltage, allowing them to run together at the rated 1600 MHz speed.
