Buying 16 GB RAM

[slocar2]

Hello i got few questions befor i buy a new RAM.
Currently my MoBo is PEGATRON CORPORATION 2AD5
specs - http://www.findlaptopdriver.com/specs-pegatron-2ad5-corporation/
At ram section is said it saupport 1600/1333 MHz non-ECC. I will buy Kingston HyperX FURY Red 16 GB ram 1866 MHz.
Now i don't know will my MoBo could use 1600MHz or 1333MHz and Should i keep my old 6 GB RAM 800MHz as second dual channel or i just use 16 GB??

Pegatron means prebuilt OEM like a Dell or HP. You will not be able to use memory faster than what's listed so don't waste money on DDR3 1866 when DDR3 1600 is as fast as it will support.

Your RAM shows as 800Mhz in CPU-Z? That means it's DDR3 1600. DDR = double data rate. It moves information on both the rising and falling edges of the clock cycle so the real speed of DDR3 1600 is 800Mhz but since it's DDR you double that for the effective speed of 1600. Memory is sold ( marketed ) at its effective speed. CPU-Z reads real speed so DDR3 1600 reads as 800Mhz in CPU-Z.

If i am correcty it wont be faster it will only have more memory??

Correct. There are some caveats there, but on a basic level, more RAM isn't going to make your PC more powerful.

Also, get a 2x8 kit. You can try to use your old RAM in a third slot as well if you really need the RAM, but RAM sticks have a tendency to not get along with different ones. RAM can sometimes even fight with the same model stick that wasn't manufactured at the same time. It's not something you can count on at all and unless you have very specific usage that requires a ton of RAM, it's highly unlikely you'd need more than 16 GB anyway.
