I'll post one tomorrow.

About using LVL 10 :

I tried running with the same settings and voltages with LVL9, but got an error at the 448k test on one of the cores.
Adding some more voltage (1.92V VDimm and MCH a notch) didn't help either, so I thought that maybe changing the Performance Level might resolve it.
And it did.

I ordered another kit today, see how that does when it arrives.
