AMD RX 480 4GB Has Actually 8GB Memory Hidden Behind BIOS Update
Okay this might come in as a surprise for many, but there is a sort of a hidden treat inside the AMD RX 480 4GB card which is being sold on retail these days. According to the reports that have flown in of late, the card actually has an 8GB memory which is unlockable with a BIOS update.
Basically, what AMD has done is ship the version of cards with two BIOS profiles – this has reportedly also been the case with the review copies that were officially sent in by the company.
So in practice, this gives the users (reviewers in most of the cases) the opportunity to test out the AMD RX 480 4GB card with both the GDDR5 memory configuration settings.
All they need to do is to jump from one profile to the other with the said BIOS update and they’ll have their hands on both the 8GB memory as well as the 4GB memory. For those who don’t know, the 8GB memory runs at 8Ghz while the 4GB runs at a slightly lower 7Ghz.
Those who have stuck with the rumor mill on this would recall that one such rumor has already been making rounds on the internet. People were claiming long before that an 8GB memory flashed as 4GB was being shipped, but not everyone believed this.
Now that we have had first hand experience of what is going on, it looks like the rumors hold water.
That being said, it is also surprising because AMD is shipping the 8GB and 4GB variants of the cards separately with separate price tags of $229 and $199 respectively.
The idea here appears to be that AMD wanted to ensure that a low priced card was available in the market which is why they went on to sell the 8GB variants covered as the AMD RX 480 4GB card.
