Expect 2-3~ fps on average in increase on every higher power state. I get stable 144 fps on CS:GO 90~ on GTA V, 70-80~ on Forza Horizon 4. You can even run your card at 900 MHz (State 2) and won't see much of a performance loss. The graphics card is now super quiet - fans don't even ramp up beyond 900~ RPM My max temps went from 84 C to 74 C without playing with the fan curve Lower power consumption (it varies from state to state. It doesn't make sense having higher voltage on a lower power state. xml file, you'll notice that it's set to 750 for State 0 and 800 for State 1.

If you save your Wattman profile and open the. Also, don't go lower than 800 mV on this one. From what I've heard, this is not really memory voltage but more of a core floor voltage setting (the minimum supplied voltage to the GPU). You have to lower that memory voltage from the default of 950 to as low as you want to go on the core voltage power states. 'Memory' Voltage Control (mV) on State 2 (Also known as GPU Core Floor Voltage): 850 mV

the graphics card completed a run of Unigine Superposition without any crashes or artifacts on State 2 with as low as 840 mV but crashed within 15 minutes of gameplay on GTA V) and I decided to increase the voltage by 20 mV across all states to ensure absolute stability. After that I played GTA V for half an hour on the lowest 1,2,3 states to check if my PC would freeze/crash during gameplay. I used Unigine Heaven and Superposition as a quick test for stability when lowering voltage. I also have a mini-ITX case (NZXT H200i) and felt the need to undervolt my Sapphire RX 580 Nitro+ 8GB too.
