So I just ran into a problem.
I have two cards on one of my rigs and I can only overclock the one that's in the main PCI-Ex16 slot.
It doesn't matter which card I put there, I can only overclock that one.
If I change the memory clock of the second card the hashrate and power consumption don't change, but every program shows that the momory clock has been changed.
My cards are MSI RX 480 gaming X 4GB and Sapphire RX470 nitro+ 4GB. Mobo is MSI X87-G55
Has anybody had the same problem or could just suggest a solution?
What overclock software you use afterburner or trixx?, i think this problem due to the brand of the gpus not the same , i have this problem with a board mounted with two cards msi and gigabyte i can overclock but can't control fans speeds efficently ,always the gigabyte one don't follow the afterburner fan set correctly.
