I have 4GB Ram on my PC I have 6GB Ram, I opened my PC and added 2GB RAM, I turn on my PC and the RAM didn't change. ( https://www.asus.com/Notebooks/X751LN/specifications/ ), it says 1x DIMM Socket what does it mean?
1| Can you please pass on the information for both the sticks of ram?
2| have you made sure your BIOS is up to date?
3| It's bad practice to mix and match rams.
