Just like motherboards, GPUs also have BIOS file(s) that are used to store and retain the default values set by manufacturers. An old hack to gain a few extra frames is to flash a cut-down variant of a particular graphics SKU with the BIOS of its full version. This overwrites the default settings and can eliminate the power and clock limitations imposed by the manufacturer making it behave like the full variant. For example, you can flash the Radeon RX 470/570 with the
Techpowerup has a massive collection of vBIOS on their website. A BIOS flashing Utility is required to flash and is separately available for AMD Radeon and Nvidia Geforce. For AMD, the latest version as of today is the ATIFlash v2.93 and for Nvidia, it is NVFlash 5.567.0.
Wccftech’s Keith May has reported on the performance improvements you can expect from a vanilla RX 5700 GPU when flashed with the RX 5700 XT vBIOS.
As expected, this raised the clocks on the Radeon RX 5700 up to the level of the 5700 XT. Power limit was also raised by 20% which helped the core go further up to 1950+MHz. Memory overclocking, unfortunately, turned out to be dud. Testing was conducted on a Z370 platform.
As we see, flashing the cut-down RX 5700
We do not, however, recommend you to try this out unless you know what you’re doing. Any mishap can potentially brick your 5700, therefore making it useless. While trying this out can be fun, simply spending an extra $50 on the XT variant could save you all the hassle completely.
