AMD Radeon RX 480 4GB version has 8GB of RAM

This is very interesting story. Generally, everyone likes to get something for free. This time¬†the gift is from AMD ūüôā It looks that they have wanted to save money on the production of AMD Radeon RX 480 series graphic cards. What did they do? The AMD has manufactured only one version of this GPU, but they sale two models.

It looks that a lot of Radeon RX 480 4 GB cards have 8 GB of memory.

Are you surprised? In order to unlock the additional 4 GB of RAM, you have to flash the BIOS of GPU. This phenomenon was observed by editors from WCCFTech. They have bought new AMD Radeon RX 480 4 GB manufactured by XFX via NewEgg online shop. In practice, they have bought 8 GB version of this graphics car but with locked half of the memory.

In order to unlock the missing memory, they have used the BIOS from XFX Radeon RX 480 8 GB Black Edition. As a result the Radeon RX 480 4 GB had been overclocked and it achieved the same performance as 8 GB Black Edition model. This is very interesting situation, because it proves that both graphics cards are identical and the only difference is the software.

The BIOS replacement is quite easy operation.

However, if you do not have any experience with similar operation then you should be careful. If you mess up something, then you may broke your graphic card. You should also prepare the backup of the original BIOS using ATIwinFlash tool. This program is more reliable than GPU-Z. Unfortunatelly, GPU-Z sometimes creates broken files which are 4 times smaller than they should.
