  1. Those caps are completely unnecessary. You can throw them in the trash and forget about them. They insignificantly reduce voltage ripple on the 12V line and you have way more than you need. A laptop GPU will have around 4 15 uF caps, and you still have 6 330 uF caps for the same purpose.

     

    I am more concerned about what damage from bending happened to the card due to the extreme force required to rip the heatsink in half. That should require well over 100 pounds of force, and very likely destroyed the card.

  2. It looks to me like your gk106 may have popcorned. It looks like the chip packaging is bulging in the lower right corner at the diagonal capacitor in the last image you linked. Did you prebake the chip at all to remove moisture?

     

    If it's not popcorned then you should try to match the hardware ID in vBIOS to what the card now calls itself. I found in optimus mode that you can have them mismatched on maxwell class GPU, but not if the card is the primary GPU. Have you tried the dGPU as primary? If you haven't yet, trying it may give you a blank screen with no way to get the iGPU back to primary without a BIOS flash via programmer. A blind normal flash or cmos battery removal often does not reset all bios settings.

  3. $70 for the drive is a bit steep for me, so I'm thinking of bidding instead of buyout unless you want to relist. I'd probably never burn a blu-ray, and there are "new" (old but unused) 12.7mm burners on ebay for less. I have had 2 optical drives die so use definitely matters.

    When you say OD caddy are you talking about the housing of the optical drive itself, or that little HDD/SSD drive caddy for housing a drive above/behind the OD?

     

    Yeah the HDD/SSD drive caddy would be good to have and I see you listed it. Mainly I want the optical drive bezel. The P150EM bezel does not match at all.

     

    The bracket for the single screw to hold the drive in would be helpful as well, although I could make that out of copper flashing.

     

    And hell, my optical drive is getting flaky, so the whole optical drive would be nice if you're willing to part with it, especially if it can read blu-ray.

     

    idk if you want to relist the caddy with the other parts included or just make another listing, so I've held off buying it for now.

  5. Do you still have the battery and optical drive caddy? I picked up a P157SM-A frame and have everything but those. The battery doesn't need to work. I just need the shell. As for the optical drive all I really need is the bezel, but the fully caddy would be nice to secure the SSD.

  6. The 980m does draw more power than the 7970m, probably around 50% more. The 7970m draws no where near 100W, while a 980m really will draw 100W. Doesn't the m17x R4 already come with a 240W power supply? You should be fine as long as you don't raise the 980m's power limit.

    Manually updating drivers means you need to change a setup file for the driver which says that installing a driver for your GPU/laptop combination is OK. Since your laptop was never released with the 980m Nvidia does not have it in the list of approved combinations. The modification is easy to do.

     

    J95 wrote a guide on how to do the modification here:

    Hi, khenglish I wanna ask you some questions

     

    I got msi gt70 with gtx 780m can I swap it with gtx 770 because it has the same gk104 or can I swap it with gtx 980? if I can swap it to gtx 980 am I must mod the vbios or anything else that I must do?

     

    Thanks khenglish for sharing this amazing experiment.

     

     GK104 and GM204 share the same BGA so physically a 980 core would be compatible, but constructing a vBIOS for the card would probably be impossible.

     

    A gtx 770 core should work. You may lose LVDS display output though.

  8. The problem with the original heatsink was it came with dual 5mm heatpipes. The 980m heatsink comes with dual 6mm heatpipes. In addition, the core radiator is 4mm thicker on the 98m heatsink vs the 680m heatsink. The extra thickness on the 780m heatsink is mostly wasted because there is no heatpipe going through the back part of the heatsink.

     

    The 780m heatsink would probably be fine for you. I don't like it because I always overvolt memory, so I need better memory cooling. The 980m would also blow FETs, which are cooled similarly to memory, so it needed better memory/power supply cooling than the 780m. Most of the heat on the memory heatsink mostly comes from the power supply circuits (power FETs, inductors), not the memory, and the 1060 uses less power than the 780m, and far less than the 980m, so it won't need nearly as much power supply circuit cooling as the 980m.

  9. I think the P150SM has the 780m heatink. The P150SM-A would have the 980m heatsink.

     

    The 780m heatsink is a single piece with one radiator. The 980m heatsink is two separate heatsinks with two radiators.

  10. What do you mean it isn't recognized? The BIOS saying the same string means nothing. It will work anyway if you install a driver.

     

    Crossflashing vBIOS typically does nothing beneficial for Clevo systems. That was just an example stating how similar the cards usually were in the Kepler days.

  11. I know BIOS has been flashed with no dGPU installed. The BIOS appears to be smart enough not to shut the system down while the BIOS is being flashed.

     

    Do you still have the dGPU you used prior to the 1060? It would be a lot less scary to flash with that installed. The card doesn't need to work, it just needs to report a temperature.

  12. Prema's BIOS runs the memory at T1 instead of T2 if you have 3 or 4 memory sticks. This could cause instability, particularly if you have over 16GB of memory. If you do pull a memory stick or 2 and it should be stable.

     

    Other than that, I have only seen freezes on boot if non-usb drives are plugged into the USB ports. Ex. the laptop treats an external keyboard as a bootable device and freezes.

     

    If the above fail, Prema's v2 Bios may have problems with the 1060. Switch the 1060 out to reflash, or just pull the card and reflash with no card.

     

    If your computer is responsive at all the flash was fine. I strongly suspect you are having a compatibility issue as described above.

  13. Often an unlocked BIOS has many extra menus that don't work. Few overclockanbe laptops have functional BIOS overclockibg menus. You want to overclock by installing Intel XTU.
