I read this post about a motherboard that supports 7 gpus.
http://cryptomining-blog.com/8556-msi-z170a-gaming-pro-carbon-motherboard-for-7x-gpus/ I did all the settings listed in the original post plus the things Gemini suggested in the comments. But i could only get 5 gpus working. When I tried to get 6 working it would bsod and give me a memory usage error. Im assuming this has to do with TOLUD but after hours and Im not exaggerating hours of looking online, searching the bios I could not find how to lower the TOLUD. If someone is willing to help me with this I swear on my kids I will send you $20 right away.
The motherboard is this one MSI Z170A Pro Carbon,
6 ASUS ROG STRIX Radeon Rx 470 8GB OC.
4gb DDR 4 memory,
Powered risers
CPU: Pentium Processor G4400 3.3 GHz FCLGA1151, power supply: EVGA SuperNOVA 1000 P2, 80+ PLATINUM 1000W
Mind you this is my first mining rig and I’m not very skilled at coding etc. I did see one website where it said how to lower the TOLUD with about 15+ steps all of which I didn’t understand. I can use cmd promt and follow directions well but the websites instructions was not for your average joe. So if anyone has this MB and can tell me where the TOLUD setting is bios I will send you $20 to paypal or an exhange of your choice.
