    Oh yeah ?

    Wish I knew this sooner, i would be trying things in the form of prevention. I want to know exactly where on the chip the component is, maybe its common enough that a small prevention can stop it from happening.

    as a seller, you know, it's a nightmare to have this happen to you, one of your clients having some crazy thing explode or catch fire, that's bad press or whatnot, so I want to make sure I can brag it never happened to me !

    (which sounds more like prevention then luck IMO)

    you know, about vbioses, no one every compliles which vbios did what... we should get that info, if either of you know which ones failed you in the past, I would make a record of it, and maybe gradually figure soemthing out to help people in the future. Imagine we find out its vbioses that were stock for a specific laptop that always failed... like if it was a 84.04.22.00.0A from MSI or like a 84.04.22.00.10/11, or even prema's EC versions or such...

    whatever it was, that info could also prove to be valuable. I'm saying it's a missing variable.

    I am actually running the card undervolted on stock clocks just to be on the safe side, and IMHO 980m is still, even at stock clocks, an amazing GPU.

    It was in the same general region, not sure if that exact chip or not.

    I knew the 980m blowing up was a matter of when not if. Overclocking is something I do for fun not just to gain a few fps. And the card blowing at stock voltage shows how shi*y nvidia''s/OEMs design & QC is - 3/6 MOSFETS-
    I had a 680M that had all components on board and overclocked like a beast.
    The last few months my card wouldn't boot up with Prema''s vbio's (custom & v2)
    At the same time the memory clocks were stable up to 3005 mhz, then it went down to 2600 mhz with anything higher and it causes weird artifacts and lockup.
    The cards sold by Woodz are probably the best cards in terms of quality and ASIC scores. The card is made in Canada after all but you can't do much if the design from the beginning is bad.

    Cost savings, As we know, One electronic component in a large yield lot indeed adds more to the BOD's pockets, Look at the BGA HQ CPUs total crapshoot (Pair that with Tripod mess and boom !), High Voltages and worst bins, trash yield from desktops come to these soldered garbage machines, Same applies for the GTX 980M and NB chipsets, iirc the Desktop ones which are not good are moved to the laptops, Ofc the handpicked chipsets are the best that money can buy :cool:

    No one makes noise in the Notebook market on gimped quality or standards, Best Example is the MXM standards /BGA fiasco and the new QHD AUO (TN) 120Hz panel which has lines due to NVSR + Hw-GSync & the b2w or b2g (don't remember exactly) of the AUO FHD AHVA (TN) 120Hz is sick, the response time is so low causing ghosting or motion blur at high refresh rates + high FPS, even the 60Hz 4K IPS GSync is not enough for 60FPS smooth response times also the 6Bit + dithering to 8Bit - quality mess, Very very awful state of mobile market, We need people numbers to win this atleast for us who are steered towards quality and perf and respect user choice over bending over to the corporates...

    Sorry for the rant but yeah sometimes these corporates trigger me :p:D

    Anyways hope the 1060 makes you happier and runs cooler and faster, Only one nitpick is 6GB of vRAM :eek::p

    Nicely said friend.
    If the 1070 didn't need any modding I might've bought it. I thought about the 6gb vram and the 192bit bandwidth but it won't make a noticeable difference. Only ROTR pushed my vram to the limit ( one game of hundreds )
    The 1060 is 20-30% over the 980m and runs cooler and consumes less than the 970m. I hope all of this will allow me to OC the hell out of it.

    Not to thread jack, but let me know if you need a 980m. I have one for sale in the forums here and it's a 4 month old woodzstack clevo model. Only powered up twice and never overclocked.
    To actually contribute to the conversation... I'm surprised to see this extreme of a failure. I'm a firm believer that cooling on the mosfet section of the card is the root cause of the failures in our older laptops. If you look at my 1070 thread you can see I added a heatpipe to cool the vrm section of my 1070 now. I had a 980m and a 1070 fail on me and with this upgrade I have gained far more stability than any other mod I have completed. If you look at all the heatsinks for laptops now that have the 10xx series they have much much more focus on cooling this section of the card.

    Going back to the OP - did your big wad of thermal pad there in the first pic not cover that chip?

    It covered half the chip on the MB and the back of the graphics card completely. From what I can see it's there for the upper vram and an insulator between the PCH and the GPU.
    The burning/spark wasn't only pointed ↓ I found staining close to the CPU and it burned through the edge of the thermal pad.

    I think we're on to something.

    Look here :

    This card still works. I was inspecting it, and it looks like it might face the same disaster in the future.
    So I've decided to have it sent in for warranty before it blows up and causes a mess.
    If anyone is unsure, take a look at your card and see 2-3 months in the condition it is in, early warning signs could save disaster!

    The card is also slightly bent at the tip now, and surely doesn't make proper contact with the heatsinks because it's not levelled , in that corner anymore.

    If I had to guess, it never made proper contact, maybe close but not close enough and after a time, it started to drift/melt/bend/slope and eventually would have caught fire and exploded/died etc..

    SO - I think we should come up with some sort of technique to prolong the life of components in higher end cards like this. Maybe a larger saturation of a cheaper by volume silicon paste that can wash off easily, and use it to create a foam or fill in area's that do not make perfect contact with the cooling pads and heatsinks.

    Or maybe some smaller/tiny copper shims and pads . Idea's and suggestions welcome. I think we could easily test these out by throwing a sensor under neath the component and seeing the results in various situations and such.

    Got to improve technique's somehow, otherwise this is the stuff that helps convince people BGA is better... when it's not.

    what the heck did you do to those resistaors ? They're all in parallel or something now ? Soldered together... might as well short them out.
