bodo Posted January 5, 2017 Share Posted January 5, 2017 (edited) Hey Folks, I am currently having tons of (admitedly scary) fun with 880M upgrade in M17XR3 (old card AMD6990M). Apart from "usual" issues with audio,DSE,throttling,heat,heatsink mods I also encountered something I didn't read about in the forums...so thought I would share the details and check if anybody made this experience too and how normal/common it is: Story: after doing a really simple benchmark to see why 880m is throttling (yaaay "PWR"), shutdown the machine for the night. btw. setup was: 372.xx drivers modded (laptopvideo2go), unigine+gpu-z+hwinfo running first, then just unigine+gpu-z next morning powerup, backlight comes up, but no "alien logo" 10-20x more powerups, still no change. bios resets, reseating of old 6990m card (no probs here), bios changes, cmos battery removing, fn-resets etc...nothing works for 880m and still see just a black screen with backlight on somehow I busted my win10 install too, so another reinstall running... in the meantime realized 880m works actually (judging by hdd/usb activity), only I see nothing...something like vbios damage? hmmm... i got to the stage where new win10 was installed (using iGFX) BIOS to defaults, audio OFF, switched again to PEG, iGFX off. 880m back in, boot and...still black/blank screen...windows booting...judging by hdd activity led. *however* after boot finished, knowing at which stage win10 was up, I just pressed briefly "alien/pwr" button to power the laptop down gracefully. boom! since next powerup I see alien logo back again, everything works, like nothing happened. 12hrs of my life gone chasing ghosts. So is this a known experience? anybody can share some more info to this? any other ways out of this trap? how to avoid it? I was not too far away from blind vbios flashing, which as seems might not have been the best idea...? Any thoughts appreciated, thx! Rgds,B.

bodo Posted January 10, 2017 Author Share Posted January 10, 2017 (edited) hmmm...ok looks I am alone on this one, that's OK. I had some more of the same trouble after, but lack of response gave me also something to think about "connection where there should not be one" so I removed the card, gave it a proper cleaning once again, also reinserted battery for further tests and since then I have not seen the issue again. The card is still giving stability issues when pushed, fighting with this currently, will keep the thread updated.
