You're right, typically you shouldn't need 1.5v + on any FX to get to 4.5GHz, that being said It can come down to the chip and the motherboard. MSI doesn't have a very good rep when it comes to overclocking the FX. Do you know how old your chip is? Some of the old original chips did take a lot of volts. I had one but it was still only 1.45v at 4.5G.
When it come to memory and amount, like E_D said we have had a lot of experience with the FX. The FX is hit and miss with the IMC in the first place, I have had at least a dozen different chips over the last few years and all of them are different. But the memory itself in that quantity comes down to physical addressing regardless of the speed. Naturally the more memory the more addressing that needs to be allocated. Each stick has chips on it we call ICs the higher the density of the stick the more chips typically. So lets just say there's 1 chip per GB that gives you 8 per stick and 32 in total that the IMC has to keep track of. Now If I use a 2x4 kit that 8 in total. This in itself makes the IMC work harder. I already made my suggestion earlier bout the ram. Unless you are video editing or doing heavy work in photoshop 32 GB of ram is just way too much, you'll never use it.
I have a CPU here that has a very good IMC and with a decent 1866 kit of 2x4 I can run the CPU_NB up to 3000+ with less than 1.3v. Right now I have that chip(9370) in my HTPC with a 2x8GB Geil 1600 kit that I bought. I had a heck of a time getting it stable with that ram. CPU_NB is at 2400 and ram at 1600 and I needed the same amount of voltage to the IMC that I did for 1866 and 3100 NB.
There is nothing written down about the "rules" for an FX and the amount of ram it can handle. Like I said though I did check the QVL list for your board and 32GB at 2133 isn't on there neith is your particualar ram at that speed. My suggestion would be to start the OC with 2 sticks around the 1600 mark. When you get stuck try adding some CPU_NB voltage instead of the core. That MIGHT help keep the V_Core down but no guarentees.
