How far can I safely overclock this GPU?

[Alcon]

Hello everyone, I was curious as to how far I can safely overclock my XFX Double D AMD Radeon R9 280 3GB graphics card?

Do you guys even think it's worth OCing it?

You could rightfully overclock it to match the 280x, roughly. They're basically the same card, save their different factory clock speeds. You could match the 280x's stock.

But of course overclocking is risky. Don't do anything without proper study

Every chip is different. So the same OC may not work for you.. if you start seeing artifacts.. or heating issues, or even lockups/blue screens, lower the overclock.

Look at the GPU-Z picture for the clocks they have.
