Dell N5110 i7 Model Ram Upgrade

It is also a function of the operating system.  WIndows 7 Home Basic is limited to 8G (64-bit), while Home Premium has a 16G limit.  7Pro/Ultimate/Enterprise have much higher RAM limits.

FYI:

I just upgraded to 16GB on my Dell n5110. Just plug  and play  :)

If you can't access that, here are the specs from the auction:

16GB (2X8GB) PC3-12800 DDR3-1600MHz non-ECC Unbuffered - LAPTOP MEMORY

CL11 204 Pin Dual Rank SO-DIMM Memory Module

Technical Specs

Memory Type DDR3 SDRAM

Capacity  8GB

Pins 204 Pin

Bus Type PC-12800

Error Correction     Non-ECC

Cas  CL11

Data Transfer Rate 1600Mhz

Voltage   1.4

That is not correct, a lot of official places say that 2x8 GB won't work, but here I am running Windows 7 Ultimate happily with 2x Kingston HyperX Impact Black 8GB 1600MHz DDR3L CL9 SODIMM 1.35V Laptop Memory (HX316LS9IB/8)

Note: I updated to BIOS A7 to A11 (don't know if it's a necessity).

The official specs are just plain wrong saying Max 8GB@1333Mhz, as you see above 16GB@1600Mhz is just fine, here's the invalid excerpt from the Setup Guide for N5110:
