I have the 1.03g revision board- As far as I can remember only the 1.03g and 1.04g boards have the option for 1.85v. 1.02g and lower only have an option for 1.65v but a pencil mod can get it up to 1.85v.
If I set it to auto the system won't boot at all @ 333 X 9
1.65v - System is unstable overclocked but stable @ stock
1.85v - Rock Solid. I've also got a 40mm fan on top of the heatsink. Even after hours of gaming the NB heatsink is barely luke warm.
BIOS 2602 was unstable for me for a while after I added a second gfx card and another 2GB of RAM. I never got around to flashing back to 2504. Strangely enough after a week or two of teething problems 2602 is now stable for me.
I've been running 1.85v since September and it's never caused a problem- heat or stability wise, but I've got an insane amount of 120mm Fans in a CM stacker case. 3 on the sidedoor, 1 on the case top, 1 on the front panel, 1 on the back panel and finally 2 more on a TRU120E heatsink. Overkill? Yes- But you'll never hear me complain about temps
