R9 390 Mod

[YakETy]

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 !

I assume you're talking about Eth.

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

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.
