I messed up pretty bad this morning, I got 4 risers I was trying to install and I mistakenly insert one riser in the wrong direction, I saw a smoke from the slot and I instantly remove the riser but little do I know that my gpu won't ever display again

Oops, I believe only a beginner can make sure mistake, anyways there is always a first time for everything, it happened to me once, it was a new card and I've not even make 30% ROI back on the card, next time you got to be careful, throw the card away because it's never going to work

Are you sure the card is dead? Find another PC and insert the card but insert HDMI display cable on motherboard instead of the card itself, if your motherboard don't have hdmi use vga and go through gpuz or msi afterburner to see if the card is detected

Sorry for your loss, we can't learn without big mistakes sometimes, I'm sure this happened to lots of people on here already, since you ordered for four risers then you have 4 graphics cards, it's not over mate, be strong

🤔 damn! You must have put the 12v on 3v in the PCie slot, forget that PCIe slot cos it's never going to work again and also the graphic card must have taken high voltage hit too, this was how I killed a R9 380 when it was freaking costly years ago, be more careful next time when dealing with risers

I still don't believe the card is dead, there must be a molex that took the current and died that's why the gpu isn't displaying, I'm not sure you can return even if warrant still covers the gpu since this is on your end, you made the mistake so there is no way out here than try to fix it or give a qualified personal to check it out, the chances of working is pretty low

I have to agree with the subject. It's also difficult mistake to make, it should have been obviously wrong
just by looking at it before reconnecting the power.

There is likely colateral damage: the GPU, the mobo (if you're lucky only 1 dead slot), the riser.
Test everything seperately to be sure.

Mistake is mistake, I'm guessing OP is a newbie to crypto mining, that can be another reason for the easy mistake, now I'm sure such will never happen again because it's going to be painful to lost such valuable item just like that, OP will learn big from this

card is dead. cost of repair maybe too expensive.

Is this a joke post?  How do you plug in a riser in the wrong direction?  Do you have a pic?  Are you referring to the part that goes in the 1x slot?

there are 2 ways to do it.

it had a four pin molex  and he put the molex in upside down.

or he plugged the 1x pcie in backwards.

both are possible to do.  but the card may have survived and the riser died.  or the pcie slot died on the mobo.

If the card was perfectly new and never used and no longer works it does not mean he killed the card.

Since he never tested it and knew it to work he can say it never worked and not be lying if he wants an rma.

He may have just killed off the riser and or the pcie slot and the new card came doa.

It can not be sure if it happened the way I just said.

For instance I have

13 amd 5500
16 amd 5600
15 amd 5700

44 good cards

and 2 DOA asus dual 5700 xt

So if that happened to me on 2 of 46 cards I would not be at fault
and on the other 44 I would be at fault.

Just saying maybe the op has legit wiggle room.

A pic ? How can you made such an error ? 0_o

It's very possible, grab a motherboard you aren't using and a bad riser connector to give a try you will see that it's 💯 possible, I killed a Nvidia card this way some time ago and it thus affects me because I couldn't get my ROI faster

The funny part is riser still works, only the connector to motherboard burns but the pcie slot and riser cable works very well, now the card isn't displaying anymore, I've tried in 5 different motherboards just to confirm but no luck

I wasn't in my best mood when building the rigs, I was so tired but couldn't postpone the building of the rig, here is what happened, I turned the riser upside down, very stupid of me

Look at that, very silly and stupid of me

As the motherboard start smoking I instantly remove the riser but it was too late, another mistake is the motherboard was in idle mode, If I've pulled the plug I may have been suspicious about how I connected the riser, it happens very fast, here is the end result

well thats was something unexpected to see this day, bad luck happen, cant rewind the situation, try to fix the gpu by using steam solder, even most likely wont fix it

so prefent in the future this mistake wont happen again, change the motherboard use with full pcie express, minimise put wrong slot

Remove the cooling system from your graphics card and check all fuses with a multimeter. You may be in luck.
You can try reading the technical documentation and figure out what this contact is responsible for. If the video chip is damaged as a result of a short circuit, sell the video card for spare parts.
Be careful and take your time.

Steam solder can't fix this type of fried gpu because this doesn't happened because of overheating, its high wattage problem so there is no way to fix the card, my advice is if warranty is still on the card OP shouldn't void that and try returning back, who knows? You can get a brand new

For one and check the qualifications of the service center workers :D

The PCIe slot is likely dead, do not plug in anything to that PCIe slot. It is possible that the motherboard also died with it, but there is very little chance of this damaging the GPU - the USB cable that connects this pciex1 inset to the riser isnt designed to carry power, and can carry very little.

Disconnect all GPU's, see if the the computer is still booting. If it does, next try checking the GPU's individually. Do NOT even try to plug anything into the slot you burned, try the rest of the slots.

This is 2017 all over again :) this was a pretty common mistake for people to make back then.

OP already confirmed that the card is dead, tested in other motherboards with no display and even tested with onboard hdmi display, the card is a gonna already, there is 12v and 3.3v connect in the PCie slots, imagine turning that around, it will surely send unwanted current into the gpu

I'm guessing the same thing happened to majority of mining newbies in crypto space, you are not the first person that goes through the same thing it once happened to me in the past and today I don't dare make the same mistakes over again, there is first time for everything now that you have made this mistake you are one Step Closer to be a pro mining rig Builder
