Hey guys, I have a Nvidia geforce GT240. Don't say it sucks cause in my country gpu are not too cheap. So only that I can afford for now. And this is my question: I have used MSI AfterBurner But I've never unlocked the voltage control cause this gpu has no 6pin connection so I scared that if I unlock it, maybe it will blown my gpu......but if I not unlocking it, maybe it cause a problem and that is I can't overclock it to 610mHz. I only can overclock it for 600 mHz. After that, the driver just stopped working and it limited to 405mHz I need to restart my to get back to 600 mHz. So, any tips in unlocking core voltage?
