what steps are needed to increase the clock speed of a dual bios amd graphics card
hello, i want to say sorry if this seems like a simple question, i've never overclocked anything before.
i'm curious about overclocking a graphic card with amd overdrive or msi afterburner. should i save the new settings on the graphics card bios?
could you clarify: if i'm using bios 2 and overclocked the card, will reverting to bios 1 restore the original settings?
if not, what steps can i follow to overclock it on bios 2 and then switch back to default by changing bios to 1?
also, which method is better for overclocking an amd graphic card—amd overdrive or msi afterburner?
feel free to ask more if you need.
thanks in advance.
The dual bios setup involves having two bios chips on the motherboard, which aids overclocking. When adjustments are made and the system starts, it usually won’t boot properly or may encounter problems. Without dual bios, you’d need to reset the CMOS to restore normal settings. With dual bios, it restores the previous bios that remained unchanged, letting you revert back without forcing a CMOS reset. This approach simplifies overclocking and helps avoid damaging the GPU by preventing unnecessary overclocking. Using MSI Afterburner or AMD tools can maintain the GPU at an overclocked state as long as they’re enabled during boot, and you can apply those settings at startup.
Also the bios is the setti ng s saved to the motherboard, ram and cpu. You do not alter gpu settings here unless it's a specific card and mobo that you can. Generally gpu are stand alone and are optional, therefore tou cant make changes to the bios. other then changing mobo voltages.
Msi afterburner is great because there is alot to work with, amd overdrive is generic and not really in depth, so I would reccomended afterburner
The concept of dual bios is distinct from common assumptions, if I understand correctly, dual bios simply refer to having two bios chips on the motherboard, which aids in overclocking because it allows you to switch between them during boot-up. Normally, changing settings might prevent the system from starting or cause problems, but with dual bios, you can revert to the previous configuration without needing a CMOS reset. This approach simplifies overclocking significantly.
Do not push your GPU beyond its limits without proper research, as this could lead to permanent damage. Using MSI Afterburner or AMD software can maintain the GPU at an overclocked state as long as it’s enabled at startup and you apply the overclock settings during boot.
I meant to clarify that I’m discussing dual bios for the graphics card, not the motherboard. What you described is motherboard dual bios. If you alter the first bios, the second one can restore the previous one, eliminating the need for a CMOS reset. However, what I’m referring to is graphics card dual bios—cards with a button to switch between settings. Bios 1 are the factory defaults, while Bios 2 are used for overclocking. If you accidentally change Bios 2, you can always reset to Bios 1 without issues, provided everything goes well.
If I successfully overclock my GPU using MSI Afterburner and set it to start with overclock settings on boot, then I would click the switch button. Will it still boot with the overclock enabled or will it revert to default? Also, does enabling MSI Afterburner to start overclock on boot preserve these settings in the card’s bios, or is it separate?
If I set MSI Afterburner to begin overclock on boot, will it always keep the GPU in an overclocked state regardless of the current bios? What method would allow me to overclock just one bios without affecting the others?
I’m new to these topics, so please let me explain more clearly.
Are you certain the switch uses dual bios rather than dual uefi?
What is your precise card number, manufacturer, and model? The dual bios on the GPU indicate it has two clocks; the first bios is set to clock 1, the second to clock 2, and altering the second won't affect the first. Reverting back to 1 will reset it to the clock settings you have configured for 1.

It's AMD Radeon 7970 GHz Edition, the original card from ATI, not made by any other company. I verified with GPU-Z and confirmed it lacks UEFI bios, which suggests it's legacy bios.
