Adding RAM that's a different speed?

First off, the specs:

CPU: AMD FX-8350 4.0 GHz
Mobo: Asus Crosshair V Formula-Z
RAM: GSkill Ripjaws X 16GB DDR3-1866
Hard Drive: Kingston 240GB SSD
GPU: Asus Radeon R9 380 4GB
PSU: Corsair CXM 750W
Windows 10 Pro

I had a buddy give me some memory the other day and I'm considering adding it to my system. I already checked it out in his build, and it works. It is Corsair Vengeance 8GB (2x4GB) DDR3 1600 MHz. The current memory I have is 16GB (2x8GB) GSkill Ripjaws DDR3 1866 MHz.

In the old days, adding memory was the go-to for increasing speed and responsiveness of a computer. It didn't matter about the speed, latency, etc., as long as the chip fit in the slot, it worked. Now, you have to worry about things like memory speed, voltage, and timing.

My question is two parts: first, should I even consider adding the memory to my system? And if so, can different memory run at different clock speeds on the same board? For example: if I have my GSkill run at 1866, and I have the Corsair run at 1600, or do all 4 sticks have to run at the same speed?

Thanks for reading/answering guys!

So 16 GB of 1866 is better than 24 GB of 1600?

It's a trap!

Your comment about "the old days" is not true, you did need to worry about all those things, there were just less variations as there were less manufacturers, and there wasn't any overclocked (out of the box anyway) memory.

As for your question, 16gb is already more than enough for modern gaming, you will not see any performance increase ans you'll never use that much memory. The fact that it will force your 1866 memory to run at 1600mhz (if it even runs) will likely make your system slower, not faster.

Thanks Rogue Leader! That makes sense to me.
