OWC 4GB DDR3 1066 PC3-8500 CL7 2Rx8 240-pin 1.5V Non-ECC UDIMM for Dell XPS 730x H2C

OWC 4GB DDR3 1066 Module for Dell XPS 730x

This OWC module is a single 4GB DDR3 1066 PC3-8500 CL7 UDIMM built for the Dell XPS 730x and 730X H2C. It runs at 1.5V with 2Rx8 organisation and no heat spreader. The part is JEDEC-standard and ROHS compliant for a warranty-safe upgrade. Buyers needing ECC or registered memory cannot use this module.

Installation fits 240-pin desktop DIMM slots

The unbuffered 240-pin DIMM plugs directly into the compatible Dell motherboard slots. It requires no extra cables, brackets or software configuration. The CL7 latency matches the system's original specification. Builders using platforms that require registered DIMMs or a different pin count cannot install this memory.

Replaces slower or smaller DDR3 sticks in the XPS

Swapping an existing 2GB or slower DDR3 module for this 4GB CL7 unit raises total capacity and keeps timing consistent. The jump is worth it when the current memory limits multitasking or large-file work. Systems already at maximum supported capacity or running a different DDR generation will not benefit.
