I have bought Acer V3-571G it has GeForce GT630.Games are running superb... but just for a 2-3 minutes until this card warms up. I have updated BIOS from 1.08 to 1.13 and the memory stopped throttling but the core does from 660mHz to 270mHz and everything works horrible. What can I do about it. This lowest result is during the game, it came back to middle 4xx mHz after I came back to dekstop, normal speed is 661,5 mHz. It makes graphics card useless.
It is common problem with Acer V3 the throttle temperature is set to too low value.
