Yes, you can mix the two RAM pairs. I don't recommend it because you won't be getting their full use. One of the pairs will have to downgrade itself to match the timing.
In addition to the speed (MHz), there is the CAS/CL spec. So even though they may have the same speed, the CAS/CL timing can be different. You should double check these values to make sure they're as identical on paper.
I'm not sure how exactly you mean stagger. The RAM slots are (from CPU to out) A1, A2, B1, B2. When you have two sticks, they go in the same number (A2, B2). So when you mention stagger, I'm not sure which stagger configuration you're referring to. But it would be one pair on 2's and another pair on 1's.
Thank you very much for your help. Everything has been running amazing
