Please help me. I have a Sapphire nitro+ rx 580 8gb 1411Mhz. I had a temperature over 75, I don't like it to go over 70.
I bought a graphics card, and it couldn't support dual monitors, I thought it was the adapter, so I ignored it.
The monitors turned off as soon as I connected the second one, the fan was at full speed, and the driver was false.
I decided to clean it. It wasn't very dirty but the pads were in very bad shape and I replaced them with 1mm pads and now I have a problem.
Now, when the graphics are loaded, the clock goes down to 1000 on the test, but it never reaches the maximum.
And after ten seconds of load, the monitor turns off and fan turn off at full speed. Turn off moniotors can fix with underclock 5 to 10 percents.
But the clock is not stable, it varies between 900 and 1100 on test, in the game 1100 MHz to 1200 MHz. The 6pin connector does not react at all, it can be done without it, it draws up to 120, 130 watts. It used to draw up to 180 watts. Gpu temps now is max 69!!!
