Hello, I changed in my Alienware m17x r3 my graphic card from 6970 on gtx 780m. GTX 780m before was used in clevo. I flash vbios modded bios: Dell.GTX780M.4096.130418 I do all things described here : http://forum.techinferno.com/alienware-m17x-aw-17/3702-m17x-r3-gpu-upgrade-gtx-780m-23.html#post71956 I have i7 2630qm processor. Max temperature on processor is 68C, on GPU 75C. In game's i have throttling, every few seconds timing drop from GPU Core from about 800 to 300, and Memory from about 1250 to 400 per 10-15 seconds and back to properly timings only on few seconds ... and throttling again. Is possible that AC is suspect? My AC have 240W ... My card throttling in 78C, i use the best paste and thermopads but card very quickly have 78C ... is any solution?
