Would adding 2 different RAM kits work?

Hi, a have a spare kit of Corsair Vengeance 8GB 1866MHz DDR3 (2x4GB) and currently running
Kingston HyperX FURY 8GB 1866MHz DDR3 CL10 DIMM (2x8GB). Would adding that spare kit work? Thanks

To slightly amend the above^ It may work. Mix and match RAM pairings don't always work. They certainly have the capacity to work, as people have gotten them to work, but there are also people that attempt to mix and match the same exact RAM and don't get the desired results. That's why I've only got 3 sticks of RAM in my machine instead of the four I bought. The fourth stick didn't play nice with the first set I bought when I made the computer.

So normally it should not work?

Na, I'm trying to get across that there isn't any 'normal' when it comes to mixing RAM kits; you could get unlucky and it will cause blue screens or just not boot, or you could get lucky and it will work but the highest speed will be the speed of the slowest RAM. There's no definitive answer but it could be a waste of money.

Hey, once put them in and get them running, how should I test to see if they're working correctly? Are there any risks of adding those? Thanks!

The only real "risks" you run would be the possible BSOD due to poor RAM or poor RAM compatibility. Blend on Prime95 does a good job of testing RAM, I believe intel burn test does as well (?), might want clarification on that one though.

Thank you for your help and feedback, I guess it's time to try it out :D

Whenever I change something to the RAM configuration in one of my PCs, the first thing I do is do a memtest burn-in for 8-20 hours.

I have wasted a week sorting out corrupted files on one of my PCs once due to a single intermittent bit in one DIMM and I'd like to avoid having to go through that again if possible. Using memtest86 lets you do a fairly thorough memory test without having to worry about HDD/SSD data corruption.
