It's possible I'm not understanding, but sometimes machines behave in confusing ways.

I need to explain this in a simpler way. I'm not too focused on fixing the problem right now, just curious about what's going on. I have an old 4690k motherboard with a Z97-GD65 chipset and two 8GB Corsair Vengeance RAM sticks. Recently, I've been using about 16GB of memory quite often, so I tried adding some 4GB sticks I had on hand to help out a bit. I know mixing RAM types isn't ideal, but I'm not aiming for the best performance here, just hoping it helps. What I found was that one of my 4GB sticks isn't working at all, the other only works in the third slot, and another 8GB stick only works in the third slot unless paired with the other 8GB stick. The last one works fine in any slot. So, some interesting observations here.
Not after each change, but I removed a few times and it didn’t work. I didn’t attempt this one yet, I’ll try later. Thanks for the help 👍 I said it didn’t make sense and seemed odd.
I've noticed you don't always need this resolved, but offering helpful comments can assist others who encounter this topic. Besides poor RAM configurations (which CMOS would fix) and the suggestion from @SupaKomputa about cleaning contacts (to remove minor corrosion or dust that increases resistance between the connector and slot), there are a couple more ideas: 1) Experiment with various stick combinations in dual-channel slots (assuming you have more than two sticks). 2) Avoid using ECC RAM in a motherboard and CPU that doesn't support it (your setup doesn't have that issue).
It's surprising it actually functioned. All four dimms are operational, though they seem a bit odd in their placement. I was able to locate one that gets recognized by the mobo, even the one I thought was inactive. Thanks to everyone!
