It took between 20 & 45minutes & Orthos blend on priority 8+

As for my NB voltage, I have to admit, I'm still not sure what to do with it. I've found I need it relatively high to run my memory at 1T but I haven't spent enough time trying to lower it and retest to know where the limit is.
It may be the 4GB or even the quad that is demanding the NB voltage but considering the extra load your NB has compared to mine your voltage isn't crazy its just surprising its that high at 400fsb which would suggest to me you couldn't get much more out of your RIG even if the CPU could do it.

I have just had a little play & my board will boot 1970fsb on 1.51v NB although you do need 1.6 + to run 3dmark & keep the bandwidth up in Everest. All other voltages are at minimum.

I haven't found a massive drop in bandwidth from 1t to 2t why don't you drop to 2t & see how low you can drop the NB voltage just out of curiosity.
