Since you already bought it all you can do is try it.
You could have bought a identical stick of vulcan memory and even that might not work. Memory is extremely sensitive to small difference in timing between the sticks.
You now in addition have 2 different brands of memory and 2 different sizes.
There actually is a pretty good chance you can get it to work but you might have to spend a lot of time testing difference timing settings in the bios.
This is so hard to say because it also depends on the motherboard and cpu chip you have. All this stuff has small difference.
This tends to be why people that don't want to deal with this mess tend to buy matched kits that are on the list of tested memory from the motherboard maker.
After you get something that will boot to windows I would boot a memtest64+ USB image and let it run overnight. If that runs with no errors you are likely good to go.
