Guest bifnewman Posted June 17, 2011 Share Posted June 17, 2011 I was thinking today, the R2 is pretty much a perfect machine. Capable of housing the most powerful GPUs and most powerful CPU's possible in a notebook (i7 940XM/920XM overclocked can match a 2920xm that cant be overclocked with throttlestop, right?), along with a beautiful 1920x1200 rgb led screen. The thing it is missing is long battery life. I know it is a desktop replacement and it isn't meant to be carried around but it is still a laptop, and longer battery life can't hurt. If someone wrote a program that automatically downclocks and undervolts the CPU and GPU and turns off the second GPU, would the battery life be much longer? Why don't programs do this already? What exactly does Windows Powersaving features do? Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted June 17, 2011 Founder Share Posted June 17, 2011 Unfortunately for us with the R2, 2920XM clock for clock is faster than the 920/940XM (even with TS on) but yes R2 is a very powerful laptop that misses the long battery life of the M17x-R3 or M18x. With the current power saving features the CPU doesn't require any undervolting, what you could do is to assign a profile on TS that will limit the multipliers and the max TDP/TDC. Now as far as it concerns the GPUs, deactivating the Crossfire X and then to turn off the secondary card would save some extra power but the program would require a reboot like the M18x when switching to IGP.Since I don't have the command center installed, I cannot try the stealth mode (the touch button that looks like a gauge meter) and see if this will limit your power consumption but you should give it a try.

Guest bifnewman Posted June 17, 2011 Share Posted June 17, 2011 Disabling crossfire doesnt require a reboot on mine (windows, it requires reboot on linux). Is this all it takes to turn off the second card? Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted June 17, 2011 Founder Share Posted June 17, 2011 By disabling cfx it won't deactivate completely the secondary gpu, it will still draw power, in order to do so, it will probably require code to be implemented to the BIOS and I don't think this is an option.

sangemaru Posted August 2, 2013 Share Posted August 2, 2013 And yet two years later, second GPU is automatically turned off by PowerPlay through ULPS Quote Link to comment Share on other sites More sharing options...
