i can get a 8gb stick of ram to combine with my 4gb both are the same company and run at 2400 or i could just get another one of the 4gb sticks
pc specs are 15 8400, no dedicated gpu yet,4gb ddr4 Hyper x Fury 2400,600 watt power suply and 1tb hard drive

in theory dual channel is faster. however, if you constantly uses more than 8gb of ram , 12gb will be better.

mixing ram not always work together

Since you are using on board video by the sounds of it I would go with the 12gb or Ram if the sticks are compatible since your on board Video uses system memory. 12 is not typically a great scenario though. Like the other person stated you want to maintain Dual Channel identical memory when possible.

AS a side note if you do go with the 12GB memory and are using on board video. some bioses allow you to control how much memory your on board video can use if this is an option for you I would go set yours to 4 GB or if that high isn't available set it as high as it will go.
This dedicates memory to your video card.

This article gets me thinking even more and the reality is your better off taking that money and buying a cheap Discrete video card. Even entry level will perform better than an on board video card.

In theory with a 4 and 8 GB stick will run in 'flex mode', which should give equivalent performance to 8 GB (2x4GB) running in dual channel plus the extra 4 GB at single channel. So getting 12 GB is strictly better. But as said above, combining sticks that weren't bought together in a kit doesn't always work.
