What this kit adds

This kit supplies 8 GB of DDR3 memory as two 4 GB SO-DIMM modules for the Alienware Phantom M11X notebook. It runs at 1066 MHz with CL7 latency and 1.5 V unbuffered operation. The 204-pin form factor matches the laptop's two memory sockets.

Before you order

Confirm the notebook is running a 64-bit operating system; a 32-bit OS limits usable memory to 4 GB. The two sockets must be populated in matched pairs for dual-channel mode. Existing 4 GB configurations may report only 3.5 GB usable depending on system allocation.

Sustained-load behaviour

JEDEC-standard DDR3 at 1066 MHz maintains stable throughput during extended workloads without thermal throttling. Unbuffered 2Rx8 organisation and fixed 7-7-7 timings deliver consistent latency. The 1.5 V supply keeps power draw predictable over long sessions.
