khenglish cheers for all your contribution and expertise on this subject. I've got a gx70 and I thought I followed the jpg pretty accurately but it actually dropped my clocks on cpuid to 1.5ghz and made my system really unstable. also increased average temps on cpu by about 10 degrees C on hwmonitor. I was using a win 8 edition of the gx70, does bar-edit not support this or am I doing something wrong? Any advice would be great cheers mate. EDIT: nvm I was using the wrong power settings. it's working now, it just overheats and crashes instead! i'll work on that undervolt now and see if I can't find a happy medium, cheers again =]
