Alienware M17x R1 DDR3 SODIMM kit

This 8 GB kit contains two 4 GB DDR3-1066 SO-DIMMs built for the Alienware M17x R1 notebook. The modules run at 1.5 V with CL7 timing and use unbuffered, non-ECC chips. Buyers needing more than 8 GB or a different DDR generation cannot use this kit.

DDR3-1066 bandwidth and OS ceiling

The DDR3-1066 interface delivers a PC3-8500 data rate that caps usable memory at 4 GB on a 32-bit operating system. A 64-bit operating system is required to address the full 8 GB. Systems limited to a lower memory bus speed will down-clock these modules automatically.

Paired installation for dual channel

The two modules must be installed as a matched pair to enable dual-channel mode on the notebook's two sockets. Mixing capacities or adding a single stick breaks dual-channel operation. The kit has no heat spreader, so it fits the standard SODIMM slots without clearance issues.

Questions about this item

Should I choose the 8GB kit with two 4GB modules or a single 8GB stick for my Alienware M17X R1?

The M17X R1 requires modules to be installed in matched pairs for dual-channel operation, so the 2×4GB kit is the correct choice; a single 8GB stick would not enable dual-channel mode.

Will the advertised 1066MHz speed actually run at 1066MHz once installed in the M17X R1?

Yes, the notebook's memory controller supports DDR3-1066, so the CL7 modules will operate at their rated 1066MHz without down-clocking.

Does the 204-pin DDR3 SODIMM interface limit the maximum usable memory on this laptop?

The platform accepts up to 8GB with a 64-bit OS; a 32-bit OS caps usable memory at 4GB, and 4GB configurations may show only 3.5GB due to system allocation.
