    Dear All,

    recently I god my hands on a Clevo p775dm3-g (XMG U717) in a seemingly good deal. It should have replaced my Lenovo y510p.

    The specs are:

    CPU, i7 7700
    GPU, mxm gtx 1080 (dead)
    RAM, 32 GB
    Storage, 256 GB SSD and 1TB HDD

    Unfortunately the graphics card died on me just after a few days and reballing had been tried without success.

    I'm am a little bit lost and don't know what to do with the machine now. I hope you can give me some advice on what kind of options I might have in this situation.

    Maybe something that has to be considered, as a student I don’t have too much resources left to invest at the moment.

    Thank you for your advice! :)

    Reballing 10 series and newer cards is very difficult. I would think most BGA repair people can't pull it off.

    If you want to just get is running, you can pick up a 1060 on ebay for low $200s. 1070's and 1080s are much more expensive.

    The system can run 20 series cards, but that requires ordering an updated heatsink.

    To add some info - There are 1060s pretty cheap, 1070s and 1080s : Folks on the forums here might have one cheaper / quicker than Ebay.

    To go to a 2070 / 2080, you'd need to source the card first (much harder than 10xx series) and pick up a matching heatsink - Best source for those is Aliexpress, pricewise.

    My recommendation would be to wait for somebody (here or otherwise) to part out a dead unit.

    How certain are you the GPU is dead?

    If you want it running it needs a GPU.

    Thank you for your answers!:)

    Also, i saw a youtube video, that explained, that reballing does not make sense usually. What is your opinion on this?



    So I guess a 1060 might be the best bang for the buck? The thing is, I have a little bit of a trust issue to order a used card on ebay after the disaster with the 1080.:(
    So I am not sure, if i should risk it. I would fear that I get a reballed card, that will die on me again after some heavy load.

    Iam pretty sure, but I am not an expert, so here are some pics that show the graphical errors during reboot:
    I might see the parts of bootmenu when booting from stick, but most of the time the graphical errors are severe and i am not be able to notice, if the system boots into the OS.

    Would it, maybe, also be a reasonable choice for me, to part out my unit and invest into another machine? What price would be reasonable for my p775dm3 without graphics card?

    He is a quackjob conspiracy theorist. Saying the EC is running a timer that makes it start acting like it needs a reball just after the warranty expires is... nuts.

    The truth is around 50% of the time you can get a complete repair by just applying flux and reflowing the problem part. The main issue with this is if it starts working again, you don't know if you got a good connection or not for the previously broken contact, and it may die again in a week. When inexperienced people try this they almost never go hot enough (> 200C numbers are too scary) or don't apply flux, so for them maybe they straighten the board a bit to temporarily bring something broken back into contact. Must exceed 217C. Usually need flux.

    For another 25% a full reball will fix it. If it works after a reball you probably soldered every connection well. With < 0.5mm solder ball size processors the past 5 years though are far more difficult to solder than older 0.5mm ball and larger.

    For the last 25% something is physically damaged on the processor, such as solder connections from the core's pcb to the core itself is damaged, and you're never gonna fix it.

    I brought the Clevo to a specialist the other day and he heated the graphics chip with some optical heat gun for some minutes up to 450°C, iirc. To be honest, it seemed a little high for my taste.
    Testing afterwards showed, that the problem got actually worse. Even more graphical errors appeared and in addition to beeping noise from the Clevo. He offered me to do the full reballing process for 180€. Fortunatelly, I only have to pay, if it works. I guess its worth a try, although 180€ seems like alot for the job.

    PS: I fixed the images. :)

    The air temperature was probably 450C, which is common. The part won't get nearly that hot.

    Those artifacts are 100% a broken connection issue. It should be fixable.

    The beeping is the the motherboard can't read the GPU core temperature. Residue flux and alcohol to clean it commonly cause this for a few hours up to a day until it dries out. I would think you still have a garbled image on the screen. If you have no image at all that is very concerning.

    If the job goes smoothly it takes around an hour. If not, which is common with newer parts, then it can take several.

    My main concern is with it getting worse that the system wasn't run enough to bake out moisture and that the GPU core's pcb literally exploded. If this happened you will see lumps in it.

    @jimmi101 That video is pointing out 'reballing' as a problem to material design problems with particular Nvidia / ATI chips on Apple (multiple generations, but here I believe he's talking about older Nvidia GPUs), a bit different than a simple production error one-off problem like on your GPU (as it seems).

    @Khenglish - Conspiracy theory, sure. He's often obnoxious, but I like much of Rossman's content, and he does run a repair business well enough!

    Wow. Almost like clockwork, two hours after yours, mine threw itself off a cliff yesterday with the same symptoms.

    I will be parting mine out I think. Just doing one last clean and reassemble to make sure it's not something dumb like dust.
