Weird issue with multiple AMD RX580's
The switches are only working on the first card so guessing its a syntax error on my behalf,
Could anyone assist (only using 3 of the 8 cards here)

epsw x -mode 1 -ftime 10 -di 0,1,2 -cclock 1150,1150,1150 -mclock 1980,1980,1980 -cvddc 950,950,950 -mvddc 950,950,950

So why would only CARD 0 use the overclock / under clock switches ? other 2 cards are using default values.

- System
Biostar BTC250 Pro (12 GPU)
8GB DDR4
50GB PageFile
Intel Celeron
8 x RX580 4GB Pulse
4 x eVGA SC 1070

Can anyone help with this, I have tried
epsw x -mode 1 -ftime 10 -di 0,1,2 -cclock 1150,1150,1150 -mclock 1980,1980,1980 -cvddc 950,950,950 -mvddc 950,950,950
epsw x -mode 1 -ftime 10 -di 012 -cclock 1150,1150,1150 -mclock 1980,1980,1980 -cvddc 950,950,950 -mvddc 950,950,950

Only the voltage on the first card is changed Sad

Hello,

It is issue with AMD drivers. I had same problem with my rig. Cards are in default clock/voltage mode if you do not connect monitor to it. You can test it if you connect monitor to second card, or connect two monitors on two cards. You will notice that now those two cards can be overclocked.
Solution 1: Install clean AMD drivers (without catalyst), just drivers - Go to device manager and manually install drivers for each card. DDU uninstall is recommended!!!
Solution 2: Buy HDMI dummy on ebay and plug it in each card.

regards. Wink

Hi, how will you enable compute mode if you only install the drivers and not catalyst/crimson?

I installed "WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.4-May3" (without software because I use RX560 which do not support compute mode)
Earlier I had installed newest beta 18 and older one from aug.. Top speeds were with Adrenalin beta but monitor problem was issue. Every time I was installing software also, and system was unstable and monitor problem was there. After few day efforts , decided to install without software and it was solution, but seed was few percent lower. Stability was great, and I could overclock.

Try different drivers, but if you can, buy HDMI plugs. Test my theory with 2 monitors on two cards. Shut down PC, connect monitor and power up.
