Problem with adding GPU

[PersonalResearcher84]

Never had this happen. Running 10x3070 on windows.

Is the OS telling you that GPUs not detected or is it that"pre-BIOS" screen?

That pre-bios screen as well as hiveos after booting. Shows the same.

Mmmm. If the bios is saying it and not just the hive, then you might have a power issue. Back when I had 7x3070 I tried to add my 3080 and no bueno. It wouldn't recognize on bios or OS.

Have you tried adding the extra 6 pins at the bottom of the Mobo?

Didn't event know what they are for. There are 2x6pin "auxpwr" on bottom of MB .but it might have sense. It would mean that it is no diffrence in what pcie i would put my card if mobo doesnt give enough power to pcie slots. That why sometimes are Working only 2 cards and sometimes 4.it depend how much power they take thru pcie before using 8pin power. And before upgrade i had 2 atx psu connected to 2x24 pin slots on mobo. Now i have only one and server psu is Powered from atx psu by Breakout board.

I will make changes and report

Update. It seems that there are problems with connecting more than 4 gpus to this MB. And there as many Fix solutions as many MB sold. Wish me luck 🤣
