I have the XT1641, following CPU-Z or DevCheck stats, the GPU is supposed to run at 550 MHz, but in my case the max frequency is 400 MHz and it seems maxed out, sometimes runs at 240 MHz but always is at 400 Mhz, don't really know if when I open a game (Real Racing 3) it max outs at 550 Mhz but I don't think so becuase it runs at 20-25 fps, is the 400 Mhz limit is for power saving? I don't have any power saver enabled but I just wanted to know.
