A-Tech 4GB DDR3 1066 PC3-8500 204-Pin SODIMM Laptop RAM

4GB DDR3 1066 SODIMM for Laptop Upgrade

This 4GB DDR3 1066 MHz PC3-8500 SODIMM module uses a 204-pin form factor designed for laptop and all-in-one systems. It operates at the standard 1.5V DDR3 voltage with CL7 latency and unbuffered, non-ECC operation. The module is built with major brand chips and tested for reliable performance in compatible AMD and Intel platforms. It serves as a direct replacement for a wide range of Dell part numbers.

Low Voltage Standard Operation

Running at the standard DDR3 voltage of 1.50V, the module draws typical power for its class without requiring elevated voltage settings. The CL7 timing at 1066 MHz ensures stable data access for everyday workloads. As an unbuffered non-ECC SODIMM, it adds minimal electrical load to the memory controller, keeping thermal output low inside compact laptop chassis. No active cooling is required or provided with this form factor.

204-Pin SODIMM Form Factor

The 204-pin SO-DIMM edge connector fits the standard DDR3 laptop memory slot found in many older notebooks and all-in-one PCs. Installation is a simple press-in action that locks the module into the socket without tools. The single 4GB stick leaves a second slot free on dual-channel boards for a matching capacity upgrade. Buyers needing ECC error correction or registered buffering for server or workstation boards cannot use this module.
