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.

Questions about this item

What limits sustained performance when the OWC DDR3 1066 CL7 module runs continuously?

The fixed 1066 MHz speed and CL7 latency set the bandwidth ceiling; with no heat spreader the chips rely on case airflow to stay within JEDEC thermal limits.

How much heat or noise does the 1.5 V unbuffered DIMM add during all-day operation?

The module draws standard 1.5 V DDR3 power and has no fan or spreader, so it adds negligible heat and zero acoustic noise beyond what the system cooling already handles.

What must the Dell XPS 730x already have for this 240-pin UDIMM to work?

A free 240-pin DDR3 slot, a BIOS that supports 4 GB non-ECC unbuffered modules, and an existing memory configuration that matches the 2Rx8 rank layout.
