There’s a lot of people who are happy with the card they bought performing exactly as intended right out of the box. Then there are those of us who shortly after install and testing begin to research ways to gain in every possible performance metric imaginable. Well this story is for those who are on a budget but also curious how to get some notable increases for their AMD 5700 cards.

Be forewarned. Modifying a product beyond the scope of its intended design can result in damage or voided warranties. Do so at your own risks! Nobody likes a bricked or burned out card. Another tip, much like cars, if it is not already performing correctly then trying make it worker harder is really not recommended.

It is somewhat common knowledge that the AMD GPUs will respond favorably to flashing their BIOS with the next highest product version. This little trick can give anywhere from 5 percent to 20 percent in performance gains. This is because manufacturers on both sides of the fence will often use many of the same parts for different tiers. Mass production is common with keeping costs down. For the consumer this means that you may have some untapped resources to unlock. From undervolting, to overclocking, and custom fan profiles, there is an assortment of tools for the enthusiast to use in the hunt for more performance. This might simply be another to use.

Keith May over at WCCFTECH did an experiment with this very trick recently and saw upwards of 20% increase in performance over the stock 5700 BIOS. Timespy and Firestrike were even higher than an overclocked 5700. As would be expected so did power draw and temperatures rise so any one thinking of doing this should make sure their power and cooling solutions are up to par first. Since the price difference between a 5700 and 5700XT is barely $50 I would not recommend getting a 5700 just to try this. This trick is really something for someone who already owns a 5700 and feels confident with the risks.

Anyone with experiences with past or present AMD cards please tell us your stories in the thread. From failures to successes I’m sure many of us would like to read them. Perhaps you have already flashed your 5700? Let us know.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
