finerek123 Posted November 15, 2014 Share Posted November 15, 2014 Hi. I installed modded bios yesterday, because i thought there is option to unlock gpu clocks on battery power. Unfortunetly i cant find it (or there isn't). Can you help me? Y510P, 4200M, 2xGT755M. Quote Link to comment Share on other sites More sharing options...
NonXtreme Posted November 15, 2014 Share Posted November 15, 2014 Not possible(at least, no one figure it out yet.) But, even if it's possible, your battery will likely die and your laptop will shut off due to the lack of power. Quote Link to comment Share on other sites More sharing options...
finerek123 Posted November 15, 2014 Author Share Posted November 15, 2014 For me its big minus. I tested 3d benchmark in Windows 7,8, Ubuntu and Debian. The same result.(Now im using windows 7). It must be limited by bios. In my old laptop there was no difference between the battery-powered or power supply. (Pentium B970 and GT620m).

NonXtreme Posted November 15, 2014 Share Posted November 15, 2014 Because your old Gt620m is low end graphic card with tdp of 16 watt (About the same as intel hd 4600 in haswell) compare to 2xgt755m which has tdp of 100 watt (50×2) that around 6 times more power hungry than gt620m.
