Sorry to ressurect an old thread, but how precise can the voltage changes be on this motherboard? (GA-MA790X-UD4P)

The manual says .1v increments for the CPU_NB and RAM...my OCZ DDR2-1150 runs at 1.8v 5-5-5-15 but I would like to run between 1.8v and 1.9v and not just jump to 1.9v. :P It's probably a misprint, but I'd like to know before it's too late. I'd also like to run no more than 1.35v -ish on the NB, I'm not going to run 1.4v 24/7. Thanks.
