Yep. Probably.
You can also check the Device Manager but I don't think I've heard of a modern PC not "knowing" which model is installed.
I'm not sure why you can't overclock it though. Perhaps your power level is maxed out already but I'm not familiar with modern AMD cards.
OK. Maybe I should get a new Power Supply then.
Sorry.
That's not what I meant. Also, I meant "Power Limit" as well.
I was only guessing that the perhaps the graphics card couldn't take any more power. In graphics cards there is a "Power Limit" that manufacturers can tell the card not to exceed.
When the Asus GTX750Ti came out for example it had more overclocking potential that people couldn't apply. NVidia initially limited it due to concerns of stability but then came out with a new driver which raised the amount of power you could apply.
Again though, I'm not certain why you can't overclock. It's either a glitch, you aren't using the software correctly, or the card is capped in software or hardware.
