    Hi,

    Currently I've got a problem where I have to underclock my 980M by -150mhz core to achieve stability.

    I've got an M17x R4 with a 980M that I bought a couple years ago. It's been working well the past couple years, mostly running stock clocks. I've also got a 3940XM running Win10. 330W PSU.

    I was trying to OC last week and I got it +225core/+400mem stable on Firestrike. I then added +37.5 mV and that's when it seemed like the damage occurred. Firestrike went to black screen 30 seconds in on the demo. Laptop stays "on" but the screen goes black and is totally unresponsive, like a hard Geforce driver crash.

    Now, Firestrike does the black screen crash at 30 seconds in on Firestrike demo even at stock clocks. If I downclock -150mhz core though there is no more crashing.

    Anyone have any thoughts on this problem? Think I did some permanent damage to my 980M with the overvolting while OCed? Curious if anyone else has had this occur.

    I haven't cracked open the back to see if there are any blown caps or anything on the card itself. I should probably take a look.

    You should take a look on both sides of the board and if there is no visible physical damage you can reflash the vBios and reinstall the drivers. I remember in the past the GTX880m had a bug that when you apply a too high overclock/overvolt and the card/driver crashes it gets stuck in an unstable state and nothing fixes that except a vBios reflash and old driver safe-mode cleaning and reinstallation.
