(adsbygoogle = window.adsbygoogle || []).push({}); Hey people. I've been trying to overclock my HD7670M for the past 3 days. I saw people getting stable 875ghz on core & 1000+ memory, i don't even know how that's possible... every time i put my core speed at 770+, it will freeze my laptop. Also, when i OC my card to 770core & 960memory, i will be stable while running benchmarks and surfing the web. But as soon as i start gaming for a few minures, it will just make my screen go colourful and full of vertical lines. PLEASE HELP ME.

I'm not sure you'd want to overclock a mobile GPU. Are you increasing the voltage on the card? Not all GPU's will overclock the same as others, just because you saw one person do it doesn't mean you are going to be able to do it too. Are you using MSI afterburner? If so you may have to tick a setting to allow you to tweak the voltage on the card. GPU's are not going to overclock well if you don't give them extra voltage to work with.

I wouldn't recommend overclocking a mobile GPU. It could be shutting down/freezing because of high temperatures as well. Are you sure you were looking of a video of the same GPU that you have?

That guy has the same GPU as me. Also, i'm using MSI AFERBURENR and i know that my card is volage blocked by BIOS. While running a benchmark on overclock, i get 55-60 celcius. I don' think it's an issue.
