    MSI 5700xt not bootable after pad change

    Hello guys,

    Finally getting around to posting here after doing some reading and searching. I have a 5700xt that was running hot on the memory, so I decided to replace the pads. I plugged it back into a riser, and the x1 portion of the riser into the motherboard. I did not see at the time that it was in backwards (so A1 and B1 were reversed, gap facing the wrong way, yes i'm a goofball). PC unexpectedly turned on upon this new input. I quickly turned it off, and was unable to get the fans to even start after resolving that.

    So, now that my idiocy is aside, I have taken to measuring various resistances of the card to try and find out what is wrong to at least learn and understand if it is fixable.

    Attached are measurements of the pcie bus (12V rails, 3V rails), power inputs, and other areas of interest. I might even have some labeled wrong as I couldn't quite find things on the internet to confirm what I'm measuring.

    I'm wondering if it is the bottom right R33 2027 which comes in a little low.

    the fact that the fans don't turn on might indicate the issue is impacting the first thing the card does upon startup.

    Thank you for all your suggestions and help.

    Unfortunately what you have described (reversing the x1 connector) is known for killing gpu dies.

    The pins on the PCIE slot are the ones that end up internally shorting the gpu die itself.

      sapphire 5700xt NB691 buck wrong output
      by pedrolopesbe
      Hello there!

      So, I have this sapphire nitro+ that is a pain as there's no diagrams of this specific model anywhere. Put that together with the fact I'm just learning.

      This buck converter is giving me 275 mV output when it should give 1.8V, I'm not sure what exactly modulates this converter and I'm going to spend the day learning about converters.
      Could be a faulty one, but I've already replaced it one time, have just another one left. I don't wanna mess up the other one if this is something damaging the component when I turn the card on.

      Ah, I don't...

      Palit GTX 980TI working via a riser but not in x16 slot
      by mmx01
      Hi,

      Interesting case, I have a gtx 980ti which suffered typical drmos failure. I replaced it together with 12V PEX switching transistors, all blown fuses etc. No shorts on vcore, vmem, pex or any other rails.

      Yet the card does not give any sign of life when plugged into pcie x16 slot unless I plug it in via a mining riser?! I was troubleshooting it using riser as it is easier to measure etc. It worked so I assembled the card put in the computer and no post. When I move it to the riser it works again.

      Checked all voltages on PCIE finger 12V, 3V3 while...

      This is really weird. We got in a Razer laptop "Blade Stealth 13"

      It came in because it was in a Windows 11 auto repair/BSoD loop. There were no dump files present on the drive which was odd. I attempted to boot into a Windows bootable USB and after selecting the USB, I would get a Windows logo and progress circle, then the system would halt and I get a BSoD. Each time the stop code is different. I have tried bootable...

      Dell Latitude 7420 BIOS Unlock Gone Wrong
      by Jeff'sTech
      Hello everyone.

      I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make...
