CMS DDR3 1333 MHz kit for Dell XPS 15z

This 16 GB kit contains two 8 GB unbuffered SODIMM modules built to the PC3-10600 standard. It targets owners of the Dell XPS 15z (L511z) notebook who need the maximum 16 GB capacity the platform supports. The sticks run at 1.5 V with CL9 9-9-9 timings and use major-brand chipsets in a 2Rx8 layout.

Upgrade from 4 GB or 8 GB factory configs

The XPS 15z ships with two slots and a 16 GB ceiling, so this kit fills both sockets and reaches the limit in one step. The jump is worthwhile when the current 4 GB or 8 GB installation leaves too little headroom for modern multitasking or larger workloads. Each module is a 204-pin DDR3-1333 part rated at PC3-10600, matching the notebook's native memory controller speed.

Verify slot count and OS before ordering

Confirm the laptop has both SODIMM sockets free, because the kit occupies the full complement of two slots. A 64-bit operating system is required to address the full 16 GB; a 32-bit edition will not use the additional capacity. The modules carry no heat spreaders and are non-ECC, matching the original specification for this system.

Questions about this item

Will the 204-pin DDR3 SO-DIMM modules fit the Dell XPS 15z (L511z) memory slots?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the two slots inside the Dell XPS 15z (L511z) notebook.

Which way round do the 204-pin DDR3 SO-DIMM sticks go in, and what click confirms they are seated?

Align the notch on the module with the key in the slot, insert at an angle, then press down firmly until both side clips snap into place with an audible click.

When should the 16 GB (2 x 8 GB) DDR3 1333 MHz kit be replaced or upgraded?

Replace the kit if memory diagnostics report errors, the system becomes unstable, or you need more than the 16 GB maximum the notebook supports.
