Radeon RX480 4GB can be flashed to 8GB version.

You mean using a a CMD window? I've tried this, even running it with admin rights. It will not play ball.

I mean DOS

I used to have a guide sticked up when it was the 5870/5850 flashing.

You need to do some searching but you make a DOS bootable USB stick and run ati flash from that. You never flash in Windows

Thanks, I looked the other day and only found Windows options. However putting the magic "DOS" into my search and I've found a guide....wish me luck.

After much research online it was found to not be possible in DOS with this generation of card.

I made a bootable windows 8 hard drive and booted into that to do it. Now rocking 8GB!
