4GB DDR3 SODIMM for select Dell laptops

This 4GB DDR3 module runs at 1066MHz with CL7 timing and 1.5V operation. It is built as a 204-pin unbuffered non-ECC SODIMM using a 2Rx8 rank configuration. The part is validated for Dell Studio 1450, 1458, 1745, 1749 and XPS 1647 systems. JEDEC and RoHS compliance ensures a warranty-safe upgrade.

Check your current memory configuration first

Verify the laptop uses DDR3 SODIMM slots and supports 1066MHz PC3-8500 modules at 1.5V. Confirm the maximum capacity per slot and total system limit in the service manual. Ensure any installed modules match this speed, voltage and non-ECC unbuffered specification for stable dual-channel operation.

Replaces slower or lower-capacity DDR3 modules

Swapping a 2GB or slower DDR3 stick for this 4GB CL7 module adds capacity and reduces latency. The jump is worth it when the system currently runs with a single channel or hits memory limits during multitasking. Buyers needing more than 4GB per slot or a different voltage should not use this part.
