OWC 2GB DDR3 SODIMM for Alienware

This OWC module is a 2GB DDR3 1333 non-ECC SODIMM built to JEDEC PC3-10600 CL9 specifications at 1.5V. It is validated for Alienware M11x R3, M15x, M17x and M17x R2 notebooks and installs in any 204-pin DDR3 slot.

Who should buy this and who should not

Owners of the listed Alienware models who need a single 2GB upgrade or a matched pair will find this module a direct fit. Systems that require ECC registered memory, a different pin count, or a larger capacity per module cannot use this part.

The specification that decides compatibility

The 204-pin DDR3 SODIMM form factor combined with 1.5V unbuffered non-ECC operation is the single requirement that determines whether the module seats and posts in the target notebook.

Questions about this item

Should I buy the 2 GB module or add a second one for 4 GB total?

Each module is a single 2 GB DDR3 1333 CL9 SODIMM; adding a second identical stick gives 4 GB in dual-channel mode if your Alienware has two slots.

What does the 1333 MHz rating deliver in daily use on an Alienware M11x R3?

The PC3-10600 1333 MHz speed matches the factory memory spec, so the system runs at its native data rate without down-clocking.

Will the 204-pin DDR3 SODIMM fit the M15x and M17x R2 slots?

Yes — the 204-pin unbuffered non-ECC DDR3 SODIMM at 1.5 V is the exact form factor used by those Alienware models.
