I also use the 01/11 bios, runs best except for a little USB trouble (keyboard disconnects and re-initializes every 2-3 days).

Don't think I need to overvolt it at 1.5 as this doesn't seem to be the right route.
Keep in mind that the bios vNB setting is undervolting.. so if you give 1,5V it's more like 1,45V really.
I also need lots of MCH for anything (probably because of quad + 4x1GB + high fsb + high memspeed), but tuning the NB GTL can also help if you want to stay low with MCH.
