Yes...a feature which only works with certain nForce-based motherboards. Believe me, it's talking about the memory on your graphics card.
Milo that sig is one of the most hilarious I've ever seen. LOL What species of bird is that btw? I thought it was a seagull at first but now I'm not sure. I hear there are some Chilean birds that look similar to seagulls. Or is that just how Australian seagulls look? If you're meaning using built in OC presets via nTune I would say gradually stepping up manually is much better btw. Glad to hear you got your problem fixed though.;)
^ Woah, just noticed the siggy! Hilarious XD! Anyway, looks like a seagull to me.
Also, great to hear you fixed your problem!
