Do I need to increase the max voltage too? Max "I think" I get is nearly 1.25V (1.212V reported by GPU-Z + +37mV available on MSI Afterburner), somehow GPU-Z doesn't show more than 1.212V even with the extra voltage applied. Maybe it didn't need it.
Thank you for your help.
TBH, voltage settings in the BIOS are not that straight forward as some people may think. The FIRST slider is the max voltage as far as I know.

I'm wondering if you know of this issue and any fix you might see in the bios to overvolt? I'm looking at least 1.225v-1.250v. I'm on water and my GPU maxes at 41C right now.

Right now the boost table is modded for 1455Mhz boost and power limit is way up, I max around 85% power. lol
The max boost clock and therefore also your max voltage (where it jumps in the boost table) is determined by several things, among them your ASIC quality.
It is possible that you have very low ASIC quality and this is the reason your card doesn't go higher than that entry in the boost table.
Please provide what boost clocks and volts you're getting with stock bios, and post your BIOS. Do you have a TESTED overclock and voltage? Otherwise I would say no need to eye higher volts if your card does fine at 1.175V at whatever clock you want it to have.
EDIT: Me dummy, I will look at the BIOS in a sec
Here we go:
1st) Edit in Common Tab your BOOST CLOCK and set it to your desired 1455.5
2nd) Look over your Voltage Table and ADJUST all values to the right WHICH ARE HIGHER than your desired max. voltage and change to your desired max voltage (I recommend 1.200V or 1.187V)
I recommend for your card 1.200V as max...actually 1.187V could even be fine. (Mine does 1506 at 1.187). Do NOT use 1.212V, your max voltage otherwise you hit voltage limit. 1.200 should be more than what you need for your 1455-1506
OK give me a few minutes, I am making you a BIOS with proper downvolting on the left too.

Asus Strix: 1455.5 Max Boost at 1.200V. Proper Voltage Table/Clocks, Increased Power Target slightly which should stop throttling in Games. This bios should run anything at 1455.5. Give it a go w/ a run of Heaven Benchmark and report whether there is any problems.
