I haven't found a single place to find all the issues that bad risers can cause. I'm pretty new to mining and so far have found a number of them.
Here are the issues that I've run into so far:
-GPU not even being recognized (Initially I thought this was motherboard BIOS problem)
-GPU going to code 43 often
-GPU causing more than normal black screen flashes
And the most annoying so far:
-GPU to cause errors in HWinfo
I kept underclocking and adding voltage, but the errors would just continue. At first, I didn't think this could be a riser related issue, but after I changed out the riser, the GPU errors went away and I was able to clock it back up to where I thought it would be. One week of frustration; SOLVED.
Anyone else see any other issues with their risers?
Edit: Forgot to add one. Problems with reported hash rate vs effective hash rate in pool mining.
Moral of the story is, test your risers!
I got the same issue that I couldnt seem to resolve, so I disabled PCIE advance options.
My mobo/PCIe was giving a lot of PCIe correction warnings (picked up by HWINFO64 as PCIe errors). The logs shows PCIe error correction.
Couldnt pinpoint the riser that gave these problems.
Seems to be random. Some riser boards would be error-less, but some combination would register those errors.
So I gave up and disabled pcie advanced options which seems to include those error correction warning reports.
Would be happy if anyone has a better solution?
