Question about NB and Bus auto vs manual and voltage

I have a fx-6100 and in my bios the Ht frequency is on AUTO 2400mhz, while the NB frequency is @ 2000MHZ. I have my chip OCed via cpu multiplier to 22x and raised voltage to [+1.750]. NB voltage is on auto as, its its multiplier. My bus is on auto ( 201.3) as well. I have been told that the bulldozers like the nb and ht freq to be equal. I have tried this with ht and nb @ 12x which gave both 2400mhz, and bus on manual which gave me 200, ram was on auto for the time being but it was read correctly. Simply my question is, can I set the NB to 12x, without setting the bus to manual, leave it at auto (201.3) and give the nb a +1 in voltage which would give it around 1.2~V?

PS I have also been getting random aero shut offs but at the time I noticed my voltate dipped to like 1.2 on the cpu, so I lowere cpu voltage to [+1.500] and turned LLC to regular ( I only have 3 options, auto, regular, extreme) Now my cpu voltage is at a constant 1.440-1.456....should I maybe lower it to [+.125] with LLC set to regular to get a slightly lower constant?

Hi cranky, that vcore seems high to me but I'm not familiar with what the 6100 likes. My 8350 runs a 1.313 20x P-state. My OC raised that to 1.404. The lower your 20x p-state voltage is (at default) the better the chip can oc.

Many amd clockers leave the ht alone and very small changes to nb voltage. About all I change is vcore, bus and multiplier. Some very good amd OC guides at overclockers.com and rog.asus.com.
