Hello guys, I got few rigs set up on this Onda B250 D8P motherboard and all share the same problem - everything works great on every possible setup, except when you put card in 1st GPU slot(the 16x one), then it gives out constant 4Mh/s from a GPU that is in the first slot and other cards get unstable hashate(keeps jumping up and down), which also gives SMOS monitor wrong info on monitoring. It works perfectly on a 7 card setup with 1st slot being empty. Works also great, when using 8 cards but one card is plugged on the small pci-e port thru a riser(again, 16x slot is empty). So my question is, are there any BIOS setting I am missing, or something else? I can already say that it cannot be a faulty board, since more than 10 rigs share the same problem.
Using SMOS, mining only ETH w/ AMD rx570 gpus, 1650w psu, celeron g3930(iirc), m.2 ssd.
If you need more details, let me know, been struggling with this for a very long time already
Any help would be appreciated, thanks in advance!
I had the same problem. change mode I think this solution.
i have 230 cards.
