Frequently Asked Questions
Will the A-Tech 4GB DDR3 1600MHz SODIMM work in my laptop?
It is built for select laptops, notebooks, and all-in-one PCs that use 204-pin DDR3 SO-DIMM slots. Check your system manual or the product listing to confirm that your model supports DDR3 or DDR3L SO-DIMMs at PC3-12800.
Is this module DDR3 or DDR3L, and what voltage does it run at?
The listing says it follows the JEDEC standard for DDR3 at 1.5V or DDR3L at 1.35V. If your laptop requires low-voltage DDR3L, check the product listing to confirm which version you will receive before ordering.
Is this ECC or registered memory?
No. It is non-ECC, unbuffered memory, which is the type most consumer laptops and notebooks use. It is not meant for servers or workstations that require ECC or registered modules.
Can I pair it with another 4GB stick for dual-channel?
If your laptop has two SO-DIMM slots, adding a second matching 4GB module may enable dual-channel operation. The module comes as single rank (1Rx8) or dual rank (2Rx8), so check your system manual for seating and channel guidelines.
