Before starting, several very logical points should be clarified. These utilities are critical, that is, the modification of the BIOS and its parameters, as well as the corresponding subsequent flashing, are the sole and exclusive responsibility of the user, who is assumed to have the necessary knowledge. to touch said parameters with values it considers Assurance.
Since HardZone We are not responsible for any problems, errors, or breakage of the graphics card or any other component derived from using these programs, so if you are unsure of what you are playing, it is best to leave it as is. is more secure. Having said that, let’s get started!
RED BIOS EDITOR and MorePower Tools, change your AMD GPU settings
The first thing to keep in mind is that it is possible that our graphics card is not supported by these programs, because although the support is growing, it always takes some time to get until ‘it is verified that it is safe.
To these two programs we have to add that we have to download the software to flash the modified BIOS, because the whole process that we are going to see deals with modifying said BIOS to leave the card to our liking, whether it is to overclock, underclock or any other setting for playing.
Therefore, we will first make the corresponding downloads, and then we will see the order of use of each program.
Once everything is downloaded, we’ll walk you through how each program works, starting with RED BIOS EDITOR.
Change your GPU’s original BIOS settings
We will have to open GPU-Z to start the process, where once opened we will have to go to the button that is in the upper right part, right next to the BIOS version and save said BIOS where we want by giving the option “save deposit”.
After that it will tell us that everything went correctly by a message as shown in the image below:
Now we open MorePower Tools, where we have to do it in administrator mode by right clicking on the “run as administrator” file. Even so, Windows will warn us that this is a potentially dangerous program, but we will ignore this warning by clicking “more info” and then “run anyway”.
After that the normal installer will open and everything is based on the typical “next, next, next” accepting the options you ask for along the way.
Once installed, the theme and appearance that MorePower Tool (MPT) will have is as follows:
In the top drop-down menu we will have to choose our GPU to start with the settings to touch.
As we can see we already have the tabs available, but the reality is that it doesn’t let us touch anything and it is because we will have to press the “load” button to load the BIOS that we previously extracted with GPU -Z. Once done, the options will be unlocked.
In our case all the options are manned except for a “zero RPM”, it is simply because we have a reference GPU from AMD, so its turbine heatsink should not stop because it has more cooling. limit.
The rest of the options should be seen from the perspective that many will be activated from AMD drivers or third-party control and overclocking programs, such as underclock or undervolt.
There really isn’t much to explain about the options as they are in themselves very descriptive and perfectly understandable.
The “Overdrive Limits” tab displays options for frequency, RPM, acoustic RPM and power limits that limit consumption, very useful if we need to extend the default range.
Power and Voltage does the same with the wattage consumption, CCT amps and voltages in each state of the graphics card. The frequency section is less complicated if possible, since it specifies the speeds in the 4 idle states of the GPU, as well as both of the Game Mode in maximum and minimum, and of course the one that AMD specifies for the SoC as tel, which is not higher than the base frequency as a rule.
The next tab, “curve”, it is better not to touch it, because these are parameters that the driver or software in question will detect to calculate the curve of GHz and volts with reference to the parameters that we have placed in the tabs previous ones.
Finally, we have the “fan” tab, where we will configure everything related to the fan of our GPU. Here you have to be careful because we are talking about the cooling of the card, so it is convenient to know what we are playing, lest it end up burning due to an error in the values.
Once everything has been changed in MPT what we are going to do is give “save” to save a file with the changed configuration and here we end with the program. We emphasize that we are not saving the BIOS as such, but a configuration file for said BIOS, so now we need to open RBE.
RED BIOS EDITOR, save your BIOS with the changed settings
As we might have guessed, RED BIOS EDITOR will need the MPT file to work, at least in part. The installation is similar to MPT, so we’ll skip this step and go back to installing as administrator for obvious reasons.
Once the installation is complete, the program interface will be as follows:
Obviously we will have to press the “load” button to load the original BIOS of our GPU, where once done, the possibilities will open up.
As we can see, we can even change the GPU ID to make it “mute” to a higher version, although this is not in practice as such. In the PowerPlay tab we will have a single option and it is nothing more than loading the file that MPT generated for us previously.
We recommend that you do not touch the VRAM Timings tab as this is a problem, but instead it is very useful if we are coming from a BIOS that is not ours, but is of another model. GPU, because here we can select our VRAM correctly and then it is important to do so.
For this we need to know which of the two models we have in our GPU. The easiest option is to use GPU-Z and see if in the Memory type section we get the manufacturer. In the event that he only puts GDDRX, we will have to open the card to be 100% sure looking at the soldered chips.
Another less recommended option is to look for a review that specifies it, but no one assures us that the manufacturer has not changed from Samsung distributor to Micron or vice versa, where blinking we would have a nice black screen after restarting, in front use a different GPU than the primary one to flash ours as a secondary one with the original BIOS and repeat the process.
It should also be borne in mind that opening the GPU may result in loss of warranty depending on the country we are in, keep this in mind, because if the screws have a sticker …
Now it would only be necessary to save the modified BIOS and with that everything would be ready to flash.
How to flash any BIOS on AMD GPUs
Once AMDvbflash is downloaded and extracted, we will need to enter MS-Dos or CMD, as Microsoft now calls it. And once inside, we will need to access the folder path. Ideally it should have been unzipped in C: and then we go into the drive or folder if we unzipped the modified BIOS that we just saved so that everything is in one directory.
Now we already need to write to the unit or folder:
With this we unlock the graphics card to prepare it for its new BIOS flash. The next step and changing the BIOS in the same drive or folder is simple, you just need to write:
- amdvbflash -f -p 0 bios.rom filename
Logically we need to replace the bios file name with the name we gave the file, in our case the specific example seen in the top image would be like:
- amdvbflash -f -p 0 biosrx5700mod.rom
After which the program will start flashing the BIOS and when it is finished it will ask us to restart the PC, after which we will access and be able to enjoy our new BIOS totally modified to our liking and surely without restrictions if we have touched the values that we have to touch.
