I bought the Gygabyte b250m gaming 3 , g400 , and a really nice 1000w PSU. I have 3 asus strix 970's
Im anle to get all the cards working in wither of the pcie x16 slot but as soon as I plug in a 1x usb riser I cant get any signal from any card in slot.
I have searched through thw bios settings a million times and just cant seem to get it working.
I have updated bios, drivers, etc.
Does this mobo have certain bios settings?
Thanks!
you can try setting somewhere in bios : PCIE link speed / speed -> GEN1
Also make sure you use 100% working 1x usb riser (try it first on the main GPU slot and make sure card is visible in device manager )and then try it on the pcie x1 slots -> Shut down pc , plug card in main slot pcie x16 , then put another one in the pcie x1 , then turn on pc . See if comes up in device manager . There shouldn't be any bios mods to make usb risers work , only if u are trying to put 4 + video cards , windows handles how the usb driver is recognised and is working. If you try above and it's not working than probably mobo might be faulty and you need to return it .
