A: Get proven Dell Alienware X51 R2 memory upgrades here. We ship approved, certified and OEM qualified modules to ensure total Dell Alienware X51 R2 system memory reliability. Nothing is perfect. Sometimes things happen. If your Dell Alienware X51 R2 memory upgrade fails at anytime–we will ship a replacement same day.

Q: What kind of graphics card does Alienware use?

A: It’s currently running a NVIDIA (R) GeForce (R) GTX 745 with 4GB DDR3 and the case only has a Alienware 240 Watt Power Supply. I know that greatly reduces my options but was hoping to get the best available for this.

Q: Do you need DIMM for X51 R2 system?

A: Factory configured X51 R2 systems often have smaller, less expensive modules. As more memory is required different density and technologies are needed. DIMM type mixing is never recommended. What is an unbuffered memory module?

Q: Why is my X51 r2 not running at 1600Mhz?

A: It is because the 1600mhz speed needs to be activated via XMP (which we cannot access to toggle on the X51 R2). From what I have managed to find out, the HyperX Fury 1600mhz sticks I listed earlier are plug and play (unlike the ripjaws) and are supposed to automatically operate at the maximum speed supported by the CPU/Motherboard.
