Okay i got my recently purchased msi gtx 570 twin frozr III with a nice factory clock of 770/1550/2000/(1000). So i started playing with the clocks, i reached 848/1696/2000 without touching voltages. im now at 910//1820/2000 with core v: 1.093 and mem and aux v ontouched. temps are around 65/75 when playing bf3. i can say for almost 100% it is stable, i tested with a few stresstester like occt 4.0, ati tool for artifacts, furmark offcourse, and some benchs; 3dmark11, heaven 2.0. and some games like bf3, stalker cop, metro 2033, rage. i leave the mem on the 2000, cause i know it won't increase fps all that much. my question here is, is it wise to continue upping the voltage to further increase the core clocks? and what does the aux voltage do? has that something to do with more power from the psu ?, cuz auxiliary means "outside" (cant find the word for it ). and i know the max operating temp of the gtx 570 core is around 105 °c but i really don't think it can last long on 105°c.. and if i increae voltage more it means more heat... ? Can anyone elaborate on the above mentioned questions. Thanks in advance..
