@dmasnikosa im a new user, so i can only upload one image. As you can see, i have a molex + usb on riser, the usb from riser go to motherboard pci and i have one 6pin on my gpu ( pny 1060 6gb requires only one 6 pin ).
When i try to turn on pc with the gpu on motherboard, the gpu fans starts working but stops a little later. In the riser, the fan stay spinning, but the gpu dont display images or are identified by the system.
Connect hdmi,dvi,vga… or whatever connection you got for monitor,screen,tv,take out the battery from mobo,be sure to previously disconnect the power,wait 15-20 sec . ,put battery back,turn the rig on. After all that,is gpu showing pic?
. Tried to remove the motherboard battery and put it again after a while, didnt work.
. Tried to put the gpu in another pc ( from where i removed the gpu on first place ), the result is the same. ( ps. before the riser thing, this gpu was used on this pc with no problems ).
. Tried another riser ( i bought 8 for start the rig ) and the usb cable starts to melt.
Considering that i dont bought any gpu, i think im gonna just forget about that and use the pieces for build another pc ( and get another gpu for my main pc ahuahhahua ).
I replace the battery, did not help.I connected old VGA cable to motherboard and the screen is visible. Windows 10 updates again and mested up all my AMD drivers. Do not know how to stop this automatic update in Windows 10.
i just signed up to like this post, because changing it to gen 1 solved the 6 hour long problem for me, i tried nvidia dch, whql drivers but no success with risers. what i found is 16X1 pcie needs to be at same datarate as other directly installed cards onboard. hence we bring down the datarate by changing it to gen 1. hope someone gets helped with this discovery.
