If its stable, good, if not, lower by 25mhz again until its stable.
Lower clocks by 25mhz on memory and core (both) but keep at 1.3v.
If you keep getting crashes past 1.3v, then you dont have a very well binned chip or memory. Now, set core and memory frequency to what you have found, at stock voltage, see if you get any crashes, if you do (because running both at max speeds can cause issues, but running only one overclocked may not), increase voltage by 50mv at a time. Dial back by 50mhz, makes sure its stable. Take memory to max until you get artifacts or crashes. Dial back by about 50mhz, make sure it is stable, i use unigen superposition on a loop. Take stock voltage, push core to max until you get crashes or artifacts. I got 1450mhz on my RX480 at 1.3v which is only 0.1v over stock.īest way to OC a gpu (and personally I used wattman, it was more consistent than afterburner because amd driver would refuse to listen to afterburner sometimes):
