Ramping up and upgrading Alienware m11x advice?

The m11x maxes out at 16Gb (2x8) of memory. Also, I believe the CPU is soldered on to the m11x and is not upgradeable.

But could I buy it with 4 gig of ram and then get technician to install 16 gig (2x8), in it? And also, does it have to be 2 8s?

The system board only has 2 slots for memory. Thus, you would need a 2x8 kit. If it comes with 4Gb it is probably a 2x2 config. So you would need to replace those sticks with the 8Gb ones.

Does that help?

Yes thank you
