Guys i have 4 x Sapphire Nitro+ RX 580 4Gb Hynix. I have modded them and it had minimal influence on mining (from 24.6 to 24.9 w/CLaymore). It's now time to overclock to get between 27 and 30 however gpuz, trixx and MSI Afterburner do not work or better, they don't detect temperature, clock and memory. Tried to uninstall all drivers with DDU, tried multiple driver version 17.x...nothing.

Any suggestion?

Thanks

I have the exact same cards, and exactly the same problem...Not even sure if flashing worked, since there was no change hashrate whatsoever. Tried getting bioses from Anorak, no change. Its as if the cards refuse to be changed. Im thinking it might be the signature check in the drivers, preventing modded stats taking effect, but i did patch the drivers, so...

You need to plug hdmi into card and restart.

OR

buy HDMI dummy

What will that do ? Sorry, but i am kinda newbie to all of this.
