Title: R9 390 Mod Post by: YakETy on November 04, 2017, 06:10:41 PM Hi All.
I have a few rigs and one with 6 x Sapphire R9 390 with TRI-X fans. They are with stock settings and i am undervolting with Afterburner. I tried to look everywhere to see if there is anything good to do on them to push them to the limit but I don't find any informations left. Can somebody explain me what to do ? I have another rig with RX 570 all bios modded on which I found informations, but for the 390, nothing... Thank you for your feedback !

The 390 is core limited not memory limited so bios mods are for the most part a waste of time, undervolt & overclock the core. My 390 is -100mV @ 1125/1500 getting 31.5MH/s + 88MH/s of lby Title: Re: R9 390 Mod Post by: YakETy on November 06, 2017, 08:02:14 PM Thank you for the feedback.
Strangely, I can't go lower than -40 Mv on mine, then the rig crashes. I will boost the core. |
