DDR3 1333MHz SODIMM for Dell laptops
This A-Tech module provides 4GB of DDR3 memory at 1333MHz (PC3-10600) in a 204-pin SODIMM form factor. It operates at the standard 1.5V with CL9 latency and uses unbuffered, non-ECC architecture. The stick is built with major-brand chips and serves as a direct replacement for Dell part numbers A3520621, A3944744 and A4501458.
Suitable for DDR3 laptop upgrades only
This module fits laptops and all-in-one systems that accept DDR3 SODIMMs at 1.5V and have a free 204-pin slot. It will not work in machines that require ECC or registered memory, nor in platforms limited to lower voltages such as 1.35V. Systems needing more than 4GB per slot or a different DDR generation must use other memory.
Speed rating PC3-10600
The decisive specification is the 1333MHz DDR3 speed grade, labelled PC3-10600. Your system’s memory controller must support this exact rate; otherwise the module will not function correctly. Verify the supported memory specifications of your laptop before ordering to ensure compatibility.
