Well luckily no such thing happened. And would it still be right to call it bricked if it still functions even with the artifacts?
That won't happen since you're not increasing memory voltage, you're just increasing frequency, which doesn't hurt VRAM in any way but if you are increasing memory voltage, then you might have a chance of ruining the memory chips, but it takes a lot of effort to ruin them, you must be determined.
Though to mention, having a frequency bump will increase temperature, and in return will degrade the memory chips over a long period of time (stability), but it won't hurt it directly. (not saying you shouldn't overclock)
