Here's my latest tune. I have 76% asic, 1.09 v was stable until 1030. 1.18v stable until 1100 . Both full load occt benches.
So here's the latest iteration of a boost fz1 bios which works well on the 6+6 version 1 cards that aren't locked, including the ones that came with f43, f21, f2. They will break hdmi on the newer v2 cards. The newer card bioses break hdmi on 6+6 cards, 2 different versions.
Normal Boost is horrid due to 1.25v and state 2 not really in use. This is optimized
Best Powertune setting for this bios is around 5-7%. If you go higher it doesn't add fps, but uses way more power.Max clocks in CCC, 1200 core, 1675 memory.
1) 1.188v boost state- stock 1000 mhz. Use CCC to set it where you find stable. I use 1100 mhz with 1660 mem.
You can't change the voltage in MSI AB, but I found this to be a good voltage that doesn't run too hot, nor is too low to get a good OC
2) 1.081v for state 2... 995 mhz. If you want test your own card with 1000 mhz or so at 1.08v to make sure its stable before using this one, because you need to hex edit to change this speed/voltage.
3) Dual mon set up to always use 0.95v even if you change ram speed. Before if you change ram speed past 1251mhz- it would use 3d voltage. (because of a stupid table that changes core voltage based on memory clocks- doesn't make sense and sucks up juice esp in multimon!)
4) UVD/low power 3d, is now 750 mhz with 750 mem 0.95v. Core clock doesn't change power use, it's the voltage- when watching uvd youtube or dxva hw accel - 500 and 750 used same power. Mem is set lower, saves a bit of power compared to 1250.
Anytime PT drops clocks below 995 mhz, it uses lower voltage and much less power to keep fps up in high demanding games. Otherwise PT just drops clocks but keeps it at the max 3d voltage...

Regular bios @ 1.188v= 22 amps (pt averaging around 970 mhz)
This bios with the 2 states = 17 amps (pt averaging around 970 mhz).
