Sorry, I saw mining support and it seemed a good forum to post this question. Didn't see it was under Bitcoin mining. I want to ask a mod to move the post to a proper subforum if needed and in the meantime, if anyone has anything useful to answer on this subject? Sad

Hi all, hope you can point me into the right direction.

I have mining rig with two rx580 8GB Aorus and two rx580 8GB ASUS Dual cards working perfectly well ( been mining and testing it without issues ). Now, when I bought one more riser cable and would like to attach Sapphire rx570 Nitro + 4GB to the RIG and I turn the PSU on after adding this GPU and press power ON button, it starts spinning, SAPPHIRE blue light pops on the GPU and then a "click" sound is heard and it begins all over again and again, never getting further away from there.

PSU is strong, 1800 W and these 5 cards should be no issue for it. Riser cable is with Molex and it is a second riser connected to the same MOLEX cable that comes out of the PSU ( have to do it, since I don't have enough MOLEX cables going out of the PSU in order to power on 6 cards ).

It's not riser fault, I tried the same GPU on another ( already working ) GPU's place on that GPU's riser cable and the exact same thing happens again.

I am out of ideas, don't know what might be causing this. It's not riser, PSU.... what could be the issue? The fact that the fifth card is rx570 with 4GB ? I doubt that.
