If my uncore ratio at 45 makes my 47 ratio cpu speed unstable, can I just add more voltage to my cpu ratio to make it stable again?

I believe that could work, but there are many reasons of why it could be unstable.

First thing, what is your VCore/Current Voltage supplied to the CPU?
Secondly, you could always lower the uncore ratio.
Third, what temperature is your CPU running at, you're clearly using water cooling.

I would try, but would not recommend, raising the VCore/Voltage a little bit, maybe to 1.4? If that doesn't work, try decreasing the clock to 4.6GHz, or something similar.

I wouldn't recommend pushing it higher than 1.38 for full time use.
I was fortunate enough to get my core speed to 5Ghz at 1.35v core, I found most of my stability problems actually came from the cache/ringbus speed, each CPU is different so you'll have to find where you can balance your core/cache speeds.

My cache can't go past 4.3Ghz but I'm only putting 1.1v through it.

I tried both the cache and Vcore at 1.33v and now it seems stable, but will do more tests
