jpfn19 Posted July 22, 2015 Share Posted July 22, 2015 Greetings, Yesterday i flashed the Prema Bios on my Clevo P151SM1-A with a gtx 870m (https://biosmods.wordpress.com/p151sm-a/) and since then i'm experiencing inconsistent framerates on games, especially on Witcher 3. When the temperature reaches >70ºC the Memory Clock of my GPU drops from 2500mhz to 2000mhz causing a slowdown(framerates drops from 30 to 20-22) in order to maintain the temperature below 70ºC. The game runned locked@30fps with temperatures between 80-85, before the BIOS flash. I've updated the Nvidia drivers and didn't worked. After I unnistaled them with DDU and installed a older version and still nothing. Already tried to go back to stock Bios, but GPU still throttles at 70ºC. The last thing i tried was format my HDD and reinstall windows, but that didn't worked either. Don´t know what to do anymore photoupload Quote Link to comment Share on other sites More sharing options...
Guest Posted July 23, 2015 Share Posted July 23, 2015 That's the 'normal' GPU throttle on GTX8xxM cards. In order to get rid of that you need to use a vBIOS Mod:http://forum.techinferno.com/general-notebook-discussions/1847-nvidia-kepler-vbios-mods-overclocking-editions-modified-clocks-voltage-tweaks.html Quote Link to comment Share on other sites More sharing options...
