I've been using the Heaven benchmark, but I've mainly been playing demanding games to test the GPU's stability. I also lowered my temp limit to 80C on Afterburner (which also lowered my power limit to -10), and I have Radeon Chill on (the only graphics setting I changed in Radeon Software so far). I'm using MSI Afterburner (because I liked their OSD), and my current voltage changes are as follows: I want to undervolt my graphics card in order to lower temperature/fan noise, and possibly gain some performance improvements if possible (I was getting upwards of 85C when gaming, and the fan noise was too loud for my liking).
Below all overclock results, measured at WQHD.Hi, I'm new to undervolting (and PC building in general) - I want to know if I'm doing the best I can to optimize my RX 580 performance. This was with the TDP Power limiter tweak maxed out. And once we teak it manually it is roughly 13% faster compared to the reference RX 480 card and thus 7% faster compared to the default MSI clocks. So RX 580 card runs give or take 6% faster compared to RX 480. To the far right where you can see Aver Difference %, this is the result of the four games tested and averaged out. In the above chart you can see relative performance difference in between a reference RX 480 card, then the AIB RX 580 card and then added the applied tweak and this our overclocked results plotted in percentage. The reference card is 100%. Tweaked with added voltage we now sit at 76 Degrees C under heavy load. We locked in the fan RPM at 45%, this is a normal to silent noise level. The GPU will max out roughly at 1500 MHz, admittedly this was borderline stable and in fact I would recommend dropping down 50 MHz for long term stability. Basically you'll gain another notch out of the graphics processor.
