Dell XPS 730x memory upgrade

This OWC module is a 2GB DDR3 1066 PC3-8500 CL7 240-pin 1.5V non-ECC UDIMM built specifically for Dell XPS 730x and 730X H2C systems. It arrives new, unbuffered, single-rank 1Rx8, and without a heat spreader. JEDEC and RoHS compliance make it a warranty-safe drop-in replacement. The 8U5D31R802GB part is tested to meet or exceed OEM specifications.

Who this suits and who it does not

Owners of the listed Dell XPS models who need a single 2GB stick to fill an empty slot or replace a failed module will find this part matches the factory speed, latency and voltage exactly. Builders working on any other platform, or users who require ECC, registered, low-voltage or higher-capacity DIMMs, should look elsewhere because this module is validated only for the named systems and does not support those features.

Deciding specification

The decisive figure is the 1066 MHz PC3-8500 CL7 rating combined with 1.5V non-ECC unbuffered 240-pin DDR3 construction; if your XPS 730x or 730X H2C calls for that exact JEDEC profile this module will work, otherwise it will not.

Questions about this item

What speed does the PC3-8500 DDR3 1066 module actually run at in a Dell XPS 730x?

The module is rated for DDR3 1066 (PC3-8500) with CL7 latency. It will operate at that speed provided the system's memory controller supports 1066 MHz; otherwise it downclocks to the highest supported frequency.

Does the 240-pin DIMM fit the Dell XPS 730x H2C motherboard slots?

Yes, the 240-pin DDR3 UDIMM form factor matches the desktop DIMM slots used in the XPS 730x and 730X H2C. No heat spreader is present, so clearance around the CPU cooler is not an issue.

How do I install this single 2 GB module, and what step do people often miss?

Power off and unplug the system, open the case, align the notch on the module with the slot key, press firmly until both retention clips click. The step often missed is verifying the BIOS recognises the new 2 GB capacity after reboot.
