How can you install more than 1 card on msi z590 a PRO?

[perspective]

Hİ EVERYONE.
i have msi z590 a pro model motherboard and I have 3090 , 3080 (lhr ) 3080 (non lhr) and 3070 … 3070 ti… TOtal they are 5 card.
I cant install more than 1 card. When i add second graphic card .On the motherboard Vga led is on and (white)
I have risers and Riser multiplier (the photos that you saw at top ) But still they are not working…
On the bios i have tried to change gen 1 -2-3 and cyrpto mining settings is on. Nothing changed…
There is 4 slot for riser on the motherboard they are all working … when i check cards alone they are all working and risers are working also . tested 1by1

CAN someone explain this who know this job ?

sounds like a bios setting holding you back still. did someone recommend a z590 chipset board for mining to you?

[perspective]

noone did recommend it. i had a good gaming pc but i just started mining. I took of the bios battery and pressed power button for 30 40 second .(also psu s were closed.).
Then i installed 5 card… with riser multiplier. Finally i can see 4 cards is working but still one of them is not working…
Also i cant open bios because it gives crash.( it was like that before i update the bios. But also with updated bios i couldnt use even second card.) i tried all options on bios with updated version… nothing happened.Thanks for your message

I’ve transfered my 8 rigs from MSI z390-A PRO to MSI Z590-A PRO and just love it. First of all no Bios setting at all unless you want to play with it but makes no difference. Out of the box I was able to connect 11 cards with NO bios changes. I have rigs with 11-3060ti and few with combination 3070 and 3080. And all of them works fine. I love MSI z590-a pro now because on z390 my bios would reset when power lost or cards replaced from UEFI to CSM boot start that disable more than 4 cards mining and the whole rig would just not work because of that and there are weird bios settings for mining on 5 plus GPUs. Not sure why you have issues with this MB but so far my best mining MB. I tried Asus B550-F, asus z590-P prime, z390 and MSI Z590-a pro is my favorite now. All rigs set up with min 8GB ram and i7 11700k processors. HiveOS on SSD and usb makes no difference on performance but I try to use SSD if I can.
I have video on YouTube on this rig and home made mining box (server case prototype).
