    GPU Repair Guide - GPU Not Detected

    Hi guys, I've done my best to put a guide together that should help anyone with a GPU that is not detected by the PC

    As usual for me these days it is a video guide. It's rather long, at 2.5 hours but there is a lot to learn, and I divided it into chapters to make it easier to consume in a few sessions.

    This video is compiled from just about all the information I have managed to find from a variety of sources. All this info is out there somewhere, so respect to the original authors - I just put it together in one package.

    I honestly believe this will help anyone who has a GPU that will not detect. Or anyone who wants to learn GPU repair. I'd be interested to know what you guys think of my efforts, and anything you feel I missed or should add. Anyway, enjoy if you like:

      Invested the time in watching the video. Very well put together. Must have taken some amount of effort to record and edit.

      I'm sure I'll go back to it many times.

        Yes it took four days to record and edit (though I don't overly edit my videos)

        Glad to see you liked it.

                      You mentioned SMBUS on pci-e aswell. Any idea what it is used for? When I probed smbus clock and data on a working card, it had nothing going on there.

                          Yes, a lot of useful information were mentioned on the video, and I believe on the channel generally.

                          Answering your question, the SMBus, is just an I2C communication protocol that has other features.. now why its there, its because its the basic way for the motherboard to talk to the GPU, this is usually send that "I am a GPU device data signal" to the motherboard, now you mentioned you didn't see anything happening on the SCL and SDA pins? when did you probe them, and for how long did you do that? they must be sending something on SDA but its also barely see-able without a good oscilloscope. I hope this is correct

                              wander why r u using 16x raiser instead of 1x raiser and 12V power from PSU for longer cables so it is easier work with cards. 16x raiser is not good when u have some pcie line bad.

                                Here`s a quick ME Firmware cleaning guide.

                                The guide is basic,its main goal is to show you how to use intel FIT,its highly recommended that you all follow the guide posted at win-raid

                                (The attached FIT version is 11, if your ME Firmware (FW) is not 11.0.*.* follow the win-raid guide. Use the tools version for your ME FW, for example: ME System Tools v9.1 For systems running ME v9.0 - v9.1)


                                A video,software (intel FIT) and practice bios are all included. I`ll post a better video and more advanced guide at a later date.

                                Inno 3d RTX2070 not detected - no I²C connection
                                by Nikan.e
                                Greetings and Salutations!

                                I have encountered a faulty GPU — an Inno3D RTX 2070 Twin. There was a shorted MOSFET on the Vcore rail.
                                The faulty DrMOS was removed, and the burned PCB area was milled away.
                                All voltages are now good, but the GPU is not being detected.

                                I found that the CS pin of the BIOS (GPU) is not being pulled low, and thus, the GPU isn't detected.
                                I wanted to measure the SM_Data and SM_Clock, but to my surprise, there is no connection at all.
                                I thought these pins were used for communication during startup?!?

                                On all...

                                Hi,
                                Got this used AOC monitor from a cybernet cafe complain of it displaying just white screen.
                                I checked the power board Changhong 715G2510 -1-4 Ver:B and detected 5vdc (both red wires) at output pin CN902. In addition, i also detected 5vdc (both red wires) at the input pin CN201 of the smaller card.(controller card?)
                                Next i checked the t con board but found only about 0.02vdc at the 5V test point. There is no other voltage detected on the t con board.
                                The only fault suspect is the controller card. My suspect could be wrong and hope someone experience can point me...
