Can't get six cards to hash on Asus z390-p motherboard

I'm setting up a new rig and can only get five cards to hash using a z390-p motherboard. I'm using hive OS, and it's recognizing all six cards, but only five are hashing.

I tried plugging in the first three cards by themselves and all of them work. Then I tried plugging in the last three cards by themselves and they work.

Maybe I did something wrong setting up the bios? There was no DMI max link speed to change. I changed PCIEex16 ports to  Gen 2, I enabled 4G decoding.

Not sure what else to do.

CMS enabled in bios.

Try plugging in 4 not 3 and see if they work.  If so then 5.
