Hi. So I bought 8 vega 56 to make a rig, thinking it would be no different than a 1080ti rig.
I can only get 5 cards to work on asus z270-a, the rest are not recognised, and sometimes a 6th comes up with problems in device manager only disappear at the next reboot. very strange.
Do you know what motherboard/driver etc can get 6+ cards running on windows ?
On linux I couldn't even boot with more than 3 cards, it would give me some pci express errors.
Also, what miner works with vega on linux with the 17.40 + rocm drivers ? or is there any way to enable old opencl for vega ?
Please advise. thanks.
Don't know much about AMD much but try this: Mobo bios settings for this build are: 1->>Sistem Agent(SA)Configuration->Above 4G Decoding>> Enable
2->>DMI/OPI Configuration->DMI Max Link Speed>>Gen2
3->>Peg Port Configuration->PCIEX 16_1 Link Speed>>Gen2
4->>PCH Configuration->>PCIe Speed>>Gen2
5->>Onboard Devices Configuration->>HD Audio Controler->Disabled
->>M.2_1 Configuration->Auto
The card is connected to the farther M2 slot from CPU
This are my settings on Asus mobo running 8 NVIDIA GTX 1070 FE 32.100 MH/s, but make sure you use the M2 adapter on amazon->>Explomos M.2 Key Wink
Also hook them one by one and update driver individually /make sure risers are working/ psu can handle / 8gb ram minimum/ win up to date. thats pretty myuch what you can do , just make sure you install them in windows and update drivers one by one / leave the m2 adapter for the last.
