    strange 680m throttling...

    Hey guys, I have a gtx 680m in my p150em laptop and recently it's been acting up on me. I normally overclock my chip to 850mhz/2300 mem clock and its been pretty solid until recently. Also, I recently upgraded drivers if it means anything. Now every time I play a game with over 90% gpu usage it throttles down to 212 randomly and I don't know why. It comes out as choppiness in game and is really annoying. Here is a picture of what I mean, excuse my fail in paint: problem.jpg

    For me, this could mean a bad card, but I really don't want to RMA this thing as i'm in school in Rhode Island and Sager is way back in California. Please could someone help a brother out? :)

    does it do that when you don't have it overclocked?

    The temps are fine. Max in demanding games are 83-84c. and no, when i downclock it to stock it doesnt throttle.

    Is it possible that this could be a power issue?

    I tinkered with the overclock a bit, and found that increasing the core clock to 850mhz and +0 for the mem clock stops the throttling, and setting the core clock to stock and increasing the mem clock to +500 also stops the throttling. However, increasing both (even with +135 core and only +10 mem) causes the throttle.

    I also found that the max OC I can reach without throttle is 810mhz core 2300 mem....however others have gotten their 680m's up to 1000 mhz without throttling so whats up?

    I got the same issue. I guess the stock voltage for our cards is too low to handle the higher clocks, causing instability. That's why I hope svl7 will update his Clevo vbios soon with a slightly overvolted version.
