I have 2 platforms on ASRock AB350 Gaming K4 (Fatal1ty)
1. 6 x AMD RX series. No problem with 6 x GPU even I have default bios
2. 6 x Nvidia (1080 x 2, p104-100 x 4). Damn, I have a lot of problems even I have last bios 4.90 and 4G above option enable.
PCIE1-1080, PCIE2-1080, PCIE3-P104-100 , PCIE4-P104-100 , PCIE5-P104-100 , PCIE6-P104-100. If I plug the last P104-100 in PCIE6, system don't boot
PCIE1-P104-100, PCIE2-P104-100, PCIE3-P104-100 , PCIE4-P104-100 , PCIE5-1080 , PCIE6-1080. System work with 6 gpu but unstable. 2 of P104-100 get "code 10 Insufficient system resources exist to complete the API", but If I disable and enable this devices in device manager then ok, all gpu (6) is work. But anyway in some causes I have a bluesscreen 0x0000009F DRIVER POWER STATE FAILURE
I tried almost everything in bios, what should I use in NB and SB, GEN1, GEN2, GEN3? Any other option? Who work well with Nvidia?
