Alienware X51 R2 DDR3 upgrade

This 8 GB DDR3 1600 module is built specifically for the Alienware X51 R2 desktop. It arrives as a single unbuffered DIMM using major-brand chips and runs at the standard 1.5 V. The kit targets owners who want a straightforward memory increase without compatibility guesswork.

Suits single-slot expansion only

The X51 R2 has two slots and a 16 GB ceiling, so this stick works best when the other slot is empty or already filled with an identical 8 GB module. Builders needing more than 16 GB total capacity or a different form factor should consider other platforms. Systems requiring ECC or registered memory are not supported.

240-pin DDR3 1600 CL11 specification

The module operates at DDR3 1600 (PC3 12800) with 11-11-11 timings and a 2Rx8 rank structure. Matching these exact speed, latency and voltage figures is the deciding factor for stable operation in the X51 R2.

Questions about this item

How can I confirm the module is running at 1600 MHz with CL11 timing after installation?

Enter the BIOS or use a tool such as CPU-Z; the memory tab should show 1600 MHz and 11-11-11 timings at 1.5 V.

What does the package contain and is anything else required for the Alienware X51 R2?

The box includes one 8 GB 240-pin DDR3 stick; the X51 R2 has two slots supporting up to 16 GB total, so a second identical module can be added later if desired.

Should I choose the single 8 GB stick or look for a 2 x 4 GB kit for this system?

The 1 x 8 GB module leaves the second slot free for a future upgrade to the 16 GB maximum, while a 2 x 4 GB kit would fill both slots immediately.
