I got a XFX RX 580 GTS XXX (RX-580P8DFD6, base clock of 1366, guaranteed OC 1386 Hz) recently and I tried to OC it, but I wasn't getting good results, then I tried to undervolt, as is a hot card and I'm in the summer. I couldn't get bellow 1130 mV in Heaven benchmark, while playing Borderlands 3 or The outer worlds it would glitch after some time, normally more than 1 hour, even with 1142 mV for the 1366 (consuming ~140 W). With 1137 it'd glitch sooner, but the power draw dropped to ~135 W.
If i just let in auto setting the power limit to +50%, the GPU would average around 1330 Hz consuming ~150 W, peaking at 160 W. If I don't touch the power limit the difference isn't big.
Then I had the idea of overclock using the auto voltage, it can get the 1386 but will reach 1200 mW (almost all the time stays above 1150) and use ~160 W.
While if I set the state 7 to 1366 and let the voltages in auto, the card would consume also around 150 W, but it'd pump its frequencies to 1366 basically all the time, but also using voltages above 1150, up to 1200.
With the graphics card consuming around 140 W, with room temperature around 20 °C, it'll get ~74 °C with 2400 rpm (almost 70%). These results are with my tower side panel open or if the 2 side fans are set at 7 V.
Obs.: I used GPU-Z for the results of the voltages, and the Radeon software while gaming.
Now the questions. Is it normal for Polaris cards to use considerably more voltage in auto mode?
Am I doing something wrong, is this bad luck in the silicon lottery, or it can be something else, like the mobo or PSU?
Can I be undervolting above the 1150 mV, as in auto is already using more than that?
Can be dangerous in the long run if I pump the voltage to 1200 mV, or at least 1160 mV, how about auto mode using 1200?
Is this power usage normal? In Heaven btw it draw around 15 less watts.
Is this a normal temperature?
Sorry for the long post.
