Single 4GB DDR3 module for Dell XPS 7100 and 8100

This OWC UDIMM provides a 4GB capacity upgrade for Dell XPS 7100 and 8100 desktops. It uses standard DDR3 technology at 1333MHz with CL9 latency. The unbuffered non-ECC design matches the original system requirements. Installation is a straightforward DIY task for most users.

DDR3 1333 PC3-10600 speed and voltage limits

The module operates at DDR3 1333 (PC3-10600) with a 1.5V requirement. Systems restricted to lower DDR3 speeds or different voltages cannot use this part. The 240-pin form factor fits only DDR3 desktop slots. Mixing with faster or slower modules will force the system to run at the lowest common speed.

2Rx8 rank configuration decides fit

The dual-rank 2Rx8 organisation is the specification that determines compatibility with the Dell XPS 7100 and 8100 memory controllers. Boards requiring single-rank modules will not accept this DIMM. Buyers needing ECC error correction or registered buffering must select a different module type.

Questions about this item

Should I choose this single 4GB module or look for a kit to upgrade my Dell XPS 7100?

This is a single 4GB DDR3 1333 module. If your Dell XPS 7100 or 8100 has free 240-pin slots you can add one or more of these modules to increase capacity.

What does the PC3-10600 1333MHz rating mean for actual system performance?

PC3-10600 1333MHz CL9 is the JEDEC standard speed for DDR3 1333. The module will run at this rated frequency and latency when installed in a compatible Dell XPS 7100 or 8100 system.

Is the 240-pin DDR3 interface compatible with the memory slots in my Dell XPS 8100?

Yes. This 240-pin DDR3 UDIMM matches the desktop DIMM slots used in the Dell XPS 7100 and 8100. It is unbuffered, non-ECC and operates at the standard 1.5V for those platforms.
