This is the ram I have installed
CORSAIR Vengeance LPX 8GB (2x4GB) DDR4 DRAM 3000MHz C15 Memory Kit - Black (CMK8GX4M2B3000C15) ======= https://www.amazon.com/Corsair-Vengeance-3000MHz-Desktop-Memory/dp/B0123ZBPDA/ref=sr_1_2?ie=UTF8&qid=1544849260&sr=8-2&keywords=corsair%2Bram%2Bddr4&th=1

This is the ram I'm planning to buy

orsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15 Desktop Memory Kit - Black (CMK16GX4M2B3000C15) ======== https://www.amazon.com/Corsair-Vengeance-3000MHz-Desktop-Memory/dp/B0134EW7G8/ref=sr_1_2?ie=UTF8&qid=1544849260&sr=8-2&keywords=corsair%2Bram%2Bddr4&th=1

Mixing sticks can be problematic, especially different sizes. If I were you I'd sell off the old ram and buy a new ram kit. Generally it's good practice to buy the same exact ram in one package to avoid any problems.

Can you mix a set of two different sizes? Yes. But are they the same cas latency, timing and recommended voltage? Just increases the chances of the BSOD.

Hope this helps.

Nothing is stopping you from doing that. Corsair does not guarantee such combinations to be compatible together.

Workarounds to get extra memory to work together include:
1) Lower memory clock speed
2) Relax DRAM timings
3) Increase DRAM voltage

I have done it with crucial dimms. I started with 1 8gb stick then a few months later picked up another one, then a few months later added a 2x4 kit to get me to 24gb total. I had no problems because i chose the same brand with the same speed and the same latency. You appear to be doing the same so in my opinion, you should be good to go.
