sorry if i was not beeing understood properly because i did not express myself clearly.
I am sure it has something to do with the pci slots. as soon as i plug in a card on the x16 slot the card can hash from 25-27 mh/s. i tried every single gpu on that the slot and everyone of them is performing good on that slot, just not on the other x1 slots.
concerning the bios settings i just mean that i put pci link speed to gen 2 and changed from onboard vga to pci vga, because i always have the hdmi plugged to a card.

I can already tell you you've done something wrong, with the asrock H81 pro btc motherboards, those you don't mess with anything to get all 6x gpus to work, I have 2x of the asrock H81 pro btc mobo's and both perform with full gpus as they should,
one full amd rx 480's with stock bios's and one full NVidia gtx 1070 rig, both of which do not need any additional messing with the bios, also on a note both rigs use risers too
another thing to consider is no gpu is the same with exception of the use of same model gpus
so if you have a rig of mixed brand gpus of course you wont get the same hashrate across the board

Hello Community,
i lately set up a mining rig working 6 RX 570 nitro + 8 GB. so far it is working fine, i got the miner set up i changed settings in the bios to get the rig booting and adjusted the gpu drivers to get all 6 cards running. the only thing that gets me worried is the fact that only my 16x pci slot seems to allows me to get higher hashrates than 22. i already tried swapping the cards to different pci slots, yet no succes, so that i can say by sure it has something to do with pci ×1 slots which for some reasons dont let me mine as fast as with the × 16 pci slot. i already looked up my problem on the internet. of course there are other people who cant get past a certain niveau regarding the hashrate, but mostly thats due to other factors like gpu type, etc. so i found nothing helpful.
hoppefully one of you out there can help my to get my problem fixed. i would send 0.1 eth to the one who knows how to fix it. i am really desperate because i cannot get my rig above ~130 mh/s although every single card can get about 27 mh/s on the pci x16 slot.
kind regards atomkuerbis
