Need help with RAM.

[mosaic1300]

I'm sorry if something like this has been answered before, I just think I have a semi unique situation. I just got done resetting my PC after 3 hours of attempting to troubleshoot this issue. I bought this PC from a reputable guy who builds PCs for professional streamers and professional players. I have 4 sticks of Corsair Vengeance Pro DDR4 Ram equaling 32gb. The guy who originally built the PC had put 2 sticks of ram equaling 16gb at 3600mhz, and I purchased another 2 sticks about a month later, but the catch is the ones I purchased are 16gb at 3200hz. I went into my BIOS and changed the DOCP profile and adjusted the RAM to the lower of my two sets of sticks. It worked fine for a day and then I was randomly doing a windows update and found myself stuck in an endless loop of BSOD. I finagled with it for about two hours before I was finally able to get it to a state where I could reset it. I set the RAM frequency and settings that I messed with in the BIOS back to the way they were which puts my RAM at a whopping 2133hz frequency. Level with me, did I screw up by A.) Not buying the same frequency sticks, and B.) Not buying them all together (for instance, they weren't in the same "batch")? Am I hard stuck at 2133hz for my 32 gb of RAM?

Yes and not just same frequency but same brand/model or at least timings, you'll now have to do your tweaking manually.
