MSI GTX580 라이트닝 Overclock Tip

I have some tips :D
-Must set clocks when temperature is warmer then -150c then cool down right before the benchmark to -180c
-Must warm card back up after benchmark to -150c before opening GPU-Z for screenshot or it will fail.
-If the pot makes a "crack" noise during the benchmark and causes failure, you must warm back up to -80c or so before you try higher clocks again. The TIM no longer is sealed to the graphics core.
-All switches on the card set to ON position.
-Make sure you are using a good thermal paste, OCZ freeze, Formula-7, titan nano etc...

Settings for clock speed 1550/1350
+449 vGPU (anything higher will cause failure (drops to 0.300v)
+200 vMem
+0 AUX
-180c during benchmark.
