Lesson learned the hard way, I killed one GPU today by mistake, I was supposed to use riser the right way but I turned it the other way, I was not in my right state of mind because of what happened at home( family issue ) so now the GPU seems dead, no display and fan is just running slow.

did it arc,spark,shut the rig down?

it may still mine on a rig with a few cards.


did you toss the riser?

if you are lucky the riser took the hit not the gpu.

try a different riser.


i did something like you did and killed a mobo board  slot but the gpu worked in other slots.

Thanks for replying, the Riser got smoked and I quickly turn the mobo off but the GPU isn't working anymore, I've even put it in my other rig thats running using hiveOS its still not working, the fan of the GPU is running so slow, I think something cut off.

When you plug the little riser adapter in backwards on the PCIE slot you will send unwanted voltage down the wrong likes into the GPU. The result 9 out of 10 times is that you send 12V into the GPU where it's expecting a very low voltage (<1v).

I only know this because I did the same thing once.  :'(

Now I use riserless boards like the BTC-S37 or I put a zip tie through that tiny hole on the riser adapter so I don't repeat the same mistake.

Hopefully it wasn't a super expensive card.

You can take apart the fan shroud and see if there is anything which blew up. If it’s something common like a capacitor you can find a replacement for it and see if it works.

Most likely you will see lots of burn marks and even PCB can be damaged. However you might get lucky and just need to replace a few capacitors.

Not the first time it happened. It happened to miners other times. Usually when they are in a rush to build a rig and end up plugging it in backwards.

I doubt you can fix this on your own, you need to find a qualified GPU repairer and send it to them, I also suspect the PCB, if you can't see any traces of burnt part on the GPU then it's bad news but I don't want to just into conclusions.

It is unlikely that you will find blew up elements on the video card board. There is no protection on these power lines. If the voltage is too high, then it gets to the video chip and this is a serious consequence. Diagnosis is possible only in a specialized workshop, it is better not to do it yourself. Even such a video card can be sold for spare parts for 30-50% of the cost.
