Yes, with one caveat which I forgot to mention!
Change the "Max Boost Clock" in Default Tab to your max stable clock, say 1481.0
Now, it can happen you changed your Boost Clock to 1481.0, but your card still only boosts to, say, 1250.
Now, look over the voltage tab and , at the bottom, the last some entries might have voltages values which are a lot higher than your card can actually supply.
(In ALL Bios I looked at, the voltage tab I looked at, the maximum voltages in the voltage table is 1281.3 (Which is WAY too high, so the card won't ever boost there but only to the clock entry in the table which has the max voltage)
*** --> Edit all the values in the voltage table which are HIGHER than your actual card's max voltage to your actual card's max voltage. Those are a bunch on the right and a few on the left. This allows the card to use the entire voltage table.
I give you an example of my own card:
My card's absolute max voltage is 1.212V (many cards are limited to 1.212V), however my card is a special case since at 1.212V it may black screen in Heaven Benchmark. So I "artificially" limited my card to a max. voltage of 1.200V (It is stable at 1481 at 1.200V)
You see in my voltage table that I changed all the values which had been HIGHER than 1.200V to 1.200V. Means the card will now boost maximum to CLK72, WHICH IS ALSO THE ENTRY IN THE DEFAULT BOOST TABLE, which is 1481.1 <--- so they match up.
The last two clocks, CLK 73 and CLK74 I put in "crazy high values" so the card never uses CLK73 and CLK74, but CLK 72 as maximum.
(Also, don't forget in the "Boost States" tab to adjust GPC MAX for P00 and P02 to whatever your max stable OC although I dont think it's really needed. But its a good thing to do anyway)
This voltage table keeps essentially the same clocks/voltages as the default BIOS so the voltages are correct, also when it boosts down.
TLDR: Adjust the voltage table so your card uses the entire table, but essentially leave the original curve and increases of voltages and don't touch them. This is how I did it.
