RED BIOS EDITOR and MorePowerTool

4. BIOS-Flash

Now comes the last and yet no less important step, namely flashing the newly created BIOS back onto our card. This is necessary, because the Adrenaline driver since 2020 extremely restricts the execution of the SPPT stored in the registry. Whoever sets the PowerLimit, the clock or voltages too high will be punished with a GPU clock of 300 MHz which can no longer be raised. In order to circumvent this deliberately built in hurdle, only the PowerPlayTables, which are permanently stored in the BIOS, help.

Even if the checksum is correct, you still need a signed BIOS in the normal way. Since the RBE cannot provide this, also for legal reasons, we have to use a Flash tool that ignores this signature or does not test it. Furthermore, the graphics card in question must also be technically supported. Currently, only the Radeon RX 5700 and the RX 5700 XT(X) can be flashed with the tool linked here from the WWW. For the RX 5600 XT this flash tool would have to be adapted. Unfortunately, the Radeon RX 5500 XT is still completely excluded from this tools.

You have to download the Flash-Tool linked below. Afterwards start the command line window with “cmd” as administrator. Otherwise it does not work. Then change to the directory where the flash tool and the new BIOS file are located. To be able to flash at all, we first have to unlock the ROM. This is done, shown below, with the call parameter “-unlockrom” and the adapter number (here the first graphics card found is e.g. “0”).

Then we call up the flash tool again with the appropriate parameters and start the flash process. Attention! Flashing is at your own risk and can lead to a bricked BIOS if not done properly or if interrupted during the process. In this case, only a second, additionally operated graphics card will help.

After flashing, the computer must be restarted. We can already admire the new data in GPU-Z. In this case I had set the boost clock a bit higher. Now the value is no longer 1925 MHz, but 2104 MHz. In real terms the card reaches 2050 MHz with the right cooling.

But this is only the beginning, because everyone can still do some fine tuning, because finally I have also set new limits for the Wattman

 

5. Checking results and overclocking in the Wattman

Let us first look at the initial situation before the BIOS flash. 1250 mV and 2039 MHz were maximum possible with GPU tuning, the power limit was at maximum +50.

Now we look at Wattman after the BIOS Flash and with a little more room in Wattman. 1250 mV at 2121 MHz and 60% power limit. However, I would like to point out again that this is not a replica setting, but only shows exemplarily what would be possible if you proceed according to the terms of use for the software.

If you receive an error message when downloading or starting our installation programs for the MPT or RBE, such as messages from inappropriate antivirus software that our official and licensed installation programs with Online Downloader detect as malware, you can safely ignore this. If in doubt, you should briefly deactivate the AV software during installation.
