How do I know when a memory OC is too high for my GT?

I know you can find out if the core is too high, there would be "snow" on the screen.

But what about when the memory is too high? I heard it causes "triangle errors" but what would it looks like and is it as easy to find as core artifacts?(like running rthdribl for 5 mins and seeing white dots all over?)

I'm not honestly sure. I've just seen most GTs crap out around 1150/1170. I've seen a few hit 1200, but typically the core overclock is lower to 'compensate'.

most likely will hard lock or just scale back to around 1.00
