Alright so I'm a pretty inexperienced budget builder and I had a question about memory, hence why I came here. So I currently have G.Skillz Ares 8gb (2x4GB) sticks in my Asus M5A99FX board. Specifically, http://www.newegg.com/Product/Product.aspx?Item=N82E168... , a pair of these. Now I have been thinking about increasing the speed of my computer to run some games better and thought about increasing the ram. Then I came across this on newegg, http://www.newegg.com/Product/Product.aspx?Item=N82E168... , these are going to be going on shell shocker later today. Now will I have a problem running these two even though they are at different speeds? I know I will have to dial back the 2133, (actually I already have my 1866 running at 2133 stable,) but they are different voltages and that's what kinda scares me. Any advice would be greatly appreciated.

I would just stick with what you have. If you were building the system new then yes get the 2133 since the shell shocker deal (I was watching that one myself) If you're just gaming you won't need 16 gb, and it certainly not worth the money to upgrade from 1866 to 2133. The mixed voltages would be fine you could run that faster set at 1866 1.5v and be fine. But I wouldn't mix the kits. If you really think you need 16gb (IE: you actually use the 8 you have right now) then you can consider this option, if not just stick with what you have.
PS: I'm surprised your 6100 will actually run memory at 2133, you're a lucky duck compaired to most.
1.5V Ram Systems tend to be more stable . Its not that 1.6V or 1.65 V will are gonna destoy your PC but they are a little more unsafe but you can change the Voltage from motherborad's BIOS with some speed cost probably. Other than that a faster ram will definately not run any games faster ( FPS etc.. ) for better and smoother gameplay you try first a better GPU and then maybe a good CPU.
So I suggest you stay were you are. No need to upgrade your RAM memory
