Been testing a 4-in-1 riser on motherboard that has only 4 slots.

Windows sees the correct count:

slot 1: 4-in-1 riser: GTX1060 (3gb), GTX1060(3gb), GTX1060(6gb
slot3: RX-570
slot4: RX-570

Client does not see the 6gb nvidia board

copro_info.xml file looks good but is missing the gtx1060 6gb board.



for what it is worth, when I tried a 4th nvidia board gtx1070, windows device manager also missed the 6gb as well as the 1070. It knew there was something attached but could not recognized the device.

Does CLinfo.exe find all cards? https://boinc.berkeley.edu/dl/clinfo.zip

Will try later. I moved one of the NVidia boards out of the 4-in-1 and put it into that empty slot-2 and all 5 were recognized by boinc.

This mombo, X8DTL-iF has a pair of x8 and a pair of x4 sockets. I will try the 4-in-1 in an x8 and see if that helps.

This was actually pretty cheap as I got it for under 90 with a pair of xeons and fans three years ago before the mining craze took off. The 6-gpu frame cost me $19 but was a PITA to assemble.

There is also a chance that it could have worked earlier as possible another reboot was needed. I need to do more testing before posting here. Usually the driver install requests a reboot but occasionally there is no notification. I will look at the clinfo.

This is all working after all. I am guessing what happened was I failed to reboot after looking at the device manager and seeing 5 devices but only 4 show up in boinc. I did restart boinc but should have rebooted. However, I have also noticed that the riser x1 adapters have variations in manufacturer. Some fit loose in the socket to where their cable weight can tip them out. Others fit tight and require a good pull to remove. I would think that if the 4-in-1 was loose then all the devices would fail, not just one.

Short Story: The 3 gtx1060 are all recognized in the 4-in-1 risers unlike when I first posted about the problem.
