With a simple BIOS flash

It appears that some reference retail/e-tail Radeon RX 480 4GB graphics cards are actually shipping with 8GB of VRAM that can be unlocked using a simple BIOS flash.

While we are quite sure that this is only a small batch of graphics cards, it is still a nice bonus if you manage to get  an additional 4GB of video memory. Both the 4GB and 8GB versions have the same number of memory chips but the 4GB one comes with 4Gbit chips while the  8GB version uses 8Gbit chips.

AMD has already confirmed that it has sent out RX 480 8GB samples to reviewers with both 4GB and 8GB BIOS that allowed reviewers to test both versions but none guessed that these would end up in retail/e-tail as well.

The first retail RX 480 4GB that can be unlocked to 8GB was spotted by and this was a Powercolor RX 480 4GB retail graphics card. already had a chance to try out the mod and run some benchmarks confirming that the card uses additional 4GB without any problems, although it does not provide plenty of performance improvements.

The only way to be sure that you get the RX 480 4GB with 8Gbit memory chips is to remove the cooler which, unfortunately, voids the warranty.
