I have VAIO S13127. It has 1GB Geforce 640M LE with 500Mhz stock clock. But in the middle of the games it underclocks to 120Mhz. I check the GPU with HWinfo and MSI Afterburner. The underclock happen when GPU temp reach over 70 and it underclocks to 120Mhz from 500Mhz.
I dont have temp problem because the temp will down to 60 when the underclock happen.
I checked this tipic:
http://forum.notebookreview.com/threads/nvidia-640m-le-core-clock-issues-sony-vaio-s-13.715094/
I set the power managment mode to prefer maximum performance. But no changes. Driver verison is 361.75.
Any Solution?
