OWC 4GB DDR3 1066 PC3-8500 CL7 2Rx8 204-pin 1.5V Non-ECC SODIMM for Dell Studio 1450 1458 1745 1749 XPS 1647

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.
