Hello. I have an Asus G75vx with gtx 670mx. I wanted oc. I'm afraid of flashing the bios because i could brick it. My current voltage (default) is 0.925 mv 600mhz/1400mhz.... msi aft let's me +135/+1000 (735/2400) and is stable. In nvidia inspector i found command keys to go to unlimited but driver crashes over 800mhz.... at 950 screen black and reset ,after that is default 600/1400. Max i can get in stable clocks (with default bios) is 770mhz /2400mhz (gpu, memory). Performance is tripled from default. ok... mi laptop is very clean (fans everithing) i get in furmark over 70* .... 75* max i got in 1hour stres test.... if i let it more i get 80*...... mi question is: how can u have 1000mhz and temp below 80*, dude u are lieing!!! at 1000 u need water cooler sistem. Aniway i'm not here to judge, i'm here to sy mi story, im very tempted to unlock gpu bios. But 75* is enough for me.... so i got 770mhz with 2400 mem (at 2800+ i get artefacts).... at 4000 they are incredible ,can't understand anithing from video images
) ..... i came close in performance to gtx 770m.... this is more than enogh for me
(mi oc is aprox 30%).... I think that at 1200mhz (double default) u need double voltage to stabilize, don't gv me +0.5mv inc (1.25v) that isn't enough , u need 1.8 at 1200 .... now this card consumes 75watts, is it posible at high oc to consume more? yes. So what u do with the 150 watt adaptor? gpu steal power from cpu and rest of computer, this is not stable sistem to me.... btw again... at 770mhz i get driver crash : 1 crash in 5hours max (in 5 seconds it restores ,i dont loose data and i continue playing). Good luck to those who push more
hope ur card doesnt melt........ ps: at 850 core clock (drivers didnt crash 2 min so i fast tested it) i got undervoltage 0.925 went to 0.900mv on graph it was waves... at 770 i get continue line. at 900 i cant test cause dont run. driver 377.5 i think,,, one person mentioned it on oc sites to be best stable driver vers.
