Question Noob question, using two sets of Ram?

[mlqc82]

I am getting ready to do my second build. I use it strictly for gaming. My current system has an older set of Corsair Vengence 16gb of ram (2x8)
My question is this:
If I buy a different set of 16gb for a total of 32gb will that cause any issues. Meaning if 2 are a certain type and the other a different type. I would probably stick with Corsair but its been a while and the exact model I have isn't made any more. Would this cause any issues?
Thanks,

Asked a dozen times a day here.
The only answer is "Maybe".

Maybe it will work, maybe it will fail.
Unless it is sold as a set and comes in the same manufacturers box...no guarantees.
