Mixing RAM memories of the same brand and latency

If I get the same manufacturer(Corsair) and the same latency(C18) but larger memory(16GBx2) and add them to existing 8GBx2 RAMs. Will it create any stability issues or will I get the benefit of more memory from this? How will this compare with only 16GBx2 sticks?

I don't think it should cause any problems as long as you follow the slot recommendations from the manufacturer to run the memory in dual channel.

This implies you will be populating all 4 of the RAM slots. As per my very limited knowledge, any issues if there are any, will probably arise from motherboard compatibility. Different motherboards have different memory topologies and not every motherboard can support running 4 RAM sticks at a high enough speed. Look up motherboard topology. Also, I found this neat little video:

Right, if same brand and specs except the size of 8gb vs 16gb it won't have any issue. I run 2 gskill and a corsair but have to run at lower speed as my gskill are of lower speed 2400mhz but if i use only gskill i can boost them to max of 2933 without issue

1. I don't understand why he says his first board wasn't compatible with 4 sticks at 3000Mhz RAM. Although it needed 3 resets initially to boot but after that it was running fine right? In his bios too he was seeing 3000Mhz at xmp.
2. When he talks about higher end and lower end boards , is he differentiating on basis of price, vrm, ram slots or something else?
3. I have a b550 pro vdh wifi that supports 4400Mhz ddr4 and I am using 3600 right now. This is one of the best boards for its class of processors when considering vrm throttling with top end CPUs as per gamer nexus.
4. As long as my system isn't crashing randomly with BSOD I am fine with the memory sticks. Right now 2x8 running fine, but not sure if 2x8+2x16 would run fine too.
