Here I thought 1.55~1.6V was plenty high for watercooling. It was enough to kill my motherboard's VRMs back when I was using AMD.
Most 955s could only OC up to 3.8~4ghz. Only the C3 chips were able to go as high as 4ghz~4.3ghz on average. If you're trying to go past 4.5ghz, you'll need to start looking at DICE, LN2, or phase change. You're lucky to have reached that point, but that's as far as you can go unless you change to next gen or Intel.
Like I said, the C2 ones barely got to 3.8~4ghz, while the C3 chips were running at 4.0~4.3ghz. OP is trying to push them a lot higher and that's where my statement comes in. Back when I was using my 955, I could barely go up to 4.5ghz even with my Rasa block.
Also keep in mind that your mobo may be limiting your OC. My 1090t only has 1.476 Vcore and 47 max core temp. But my mobo makes anything higher unstable. I'm guessing your temps are fine with your WC, which is why I think your mobo may be what's setting the ceiling.
