I am building a computer and already have 4x4G G.skills 1600MHz Ripjaws X. My question is whether or not it would be compatible to add 4x8G G.skills 1600MHz Ripjaws X? Or will I have to sell the 4Gs and go with 8Gs across the board?? My interest is to run a decent size DRAM for graphic designing and maybe run my games off of as well.

Solution
If getting 4x8GB regardless, then give it a try, I wouldn't recommend going out and buying with the intent of mixing, but since getting them anyway might as well try them together...To have high hpes of bothe sets playing well, go with same manufacturer and preferably the same model and timings if possible i.e. look for the 4x8GB Ripjaws X in 1600 with the same CL (often 9 with the RJ lines)...then set up the new set first, enable XMP and get them stable, then add the 4x4GB, don't be surprised if it doesn't work, almost guarantee we'll need to make some voltage adjustments and prob a couple adjustments in the advanced timings, but have had success with this before ;)

Ram is sold in kits for a reason.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.
Although, I think the problem has lessened with the newer Intel chipsets. Still,
it is safer to get what you need in one kit.
In particular for 8 sticks I think it will be more important that they be matched.
Go to the g.skil web site and access their ram configurator.
Enter your motherboard and you will get a list of compatible kits.
If you would be happy with 32gb, then you could buy the 32gb kit and hope that your 16gb kit works well with it.
If you want more, I think you are looking at a 8 x 8gb 64gb kit.
