Compatible Dell XPS 15Z Memory Upgrade

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Dell XPS 15Z (L511Z). The parts run at 1333 MHz with CL7 timing and operate at the standard 1.5 V. Installation is a straightforward notebook memory upgrade.

Suits owners of the Dell XPS 15Z (L511Z)

Buyers with a different laptop model cannot use these modules because the kit is validated only for that system. Users who need more than 8 GB or who require ECC or registered memory should look at other options.

Dual-channel 2 x 4 GB configuration

The kit provides a matched pair so the notebook can run in dual-channel mode. Each stick is a 204-pin unbuffered non-ECC module rated PC3-10600, giving the exact specification that decides fit and function.

Questions about this item

What speed does the DDR3 1333 PC3-10600 interface cap at in practice?

The modules run at 1333 MHz with PC3-10600 bandwidth and CL7 timing, so the memory bus tops out at that DDR3-1333 rate in the Dell XPS 15Z.

What physical slot and form factor do the two 4 GB sticks need to fit the Dell XPS 15Z L511Z?

Each stick is a 204-pin DDR3 SO-DIMM without a heat spreader, matching the two SODIMM sockets in the notebook.

How are the modules installed and what step is often missed for dual-channel mode?

Insert both 4 GB sticks into the two slots; the system requires matched pairs in both sockets to enable dual-channel operation.
