I have the EVGA SC GTX 950 and have had a 80 MHz overclock on the core and 300 MHz overclock on the memory since I got it. Recently certain games such as Half Life 2, Minecraft, and recently CS GO are causing it to lock the core at 405 MHz. I understand that the card has a safe mode for when it crashes and it reverts to 405 MHz but nothing is crashing. The driver isn't crashing and the game isn't crashing. It never boosts above 405 MHz and playing a certain game will lock it there until I restart my PC which is really frustrating. Even if i revert to stock clocks it still does this. I haven't been able to find out much by googling around other than that its in safe mode and theres no reason for it to be. I validated my overclock by running fur mark, heaven, and valley for over an hour each. I played BF4 for 5 hours straight the other day and the card didn't even have a hiccup and yet these games that a laptop can run are choking up the card and causing problems. Any help would be appreciated
