Dear miners , i am having problem with booting my rig after installing 6. card to it , please help.
My setup is:
Asrock H81 btc pro (tried new mbo bios , no luck)
Gigabyte 3x rx 470 and 3 x rx 570 (gaming versions and bios moded)
celeron + 4gb ram
risers are usb powered ver003
newest rx 570 drivers
PSUs are 2 x fortron Hyper 700w (1400w together)
So if I plug any 5 cards in motherboard pc boots and I patch them because moded bios.
After restart PC device manager recognizes them all and everything works just fine.
But if i insert 6. gpu (doesnt matter which one) , pc restarts and wont boot.
With 5 cards i can se fan stop led on my gpus how turns on card by card from top pcie slot to the bottom.
But with 6 cards led turns on first on x16 slot card and after that all gpus turn off and back on.
Is there any help guys?
