I think I need to do pin shorting but can someone confirm ? I cannot see this mobo in the list.
That isn't an all inclusive list. Try the A1 B17 jumper and see if it detects. It's a quick troubleshooting step to find out if that is your issue.
yes and no on the ' quick ' part, there are a few posts later in there that reqired 1 slot empty on a board that had 7 slots and a similar ( not from the same manufacturer ) where 1 slot needed a jumper, the rest didn't. It's a long read and could be worth it for alt coin mining as GPUs are still cheaper to get ( for me at least, and only the older OpenCL ones ) than dual miners or the new asic script miners.
