Black Screen after More Power Tool

[Cthulhu 76]

Hello. I have a problem and I hope for a solution. I saw a video of Igor's Lab on YouTube, where he "edits" an RX 6800 with the More Power Tool (MPT) to get more power out of the Wattman. Did it like in the video. So read out the BIOS of the card with GPU-Z and save it on the computer. Then select my card in the MPT with the tab and read in the saved BIOS of the graphics card. Like I said, just follow the video. After reading the card's BIOS, the memory clock (also shown in the video) is increased from 1050 to 1100. Then saved via Write SPPT. Then rebooted the PC. However, I now have a black screen on both monitors. Already tried everything, only with one monitor, tried another DP cable, tried HDMI cable, card removed and reinserted, tested RAM individually, checked power supply cabling. But the computer boots normally, the RGB lighting shines merrily, as does that of the mouse and keyboard. When Windows 11 boots, I hear that through the headphones. Can also enter my Windows password and then the RGB lighting will change. I just have a black screen. What can I do now? Would I still have the problem if I test another RX 6800? Or with an RTX card? Sorry that I might be asking a stupid question, but what exactly did the MPT do? Rewrite the card's BIOS? Or changed something in the Windows (Registry)?

I'm not at all familiar with this tool, I read the description and it sounds like it can flash the BIOS (using console commands?), since there are disclaimers/warnings that suggest this on the tool's page, but it's not clear if it actually does, maybe this is your choice?

Do you have onboard graphics available?

 

[Hyburnate]

What worries me is you don't actually know what you did...

Is it possible to reset or reflash the cards BIOS?

 

[Thekwango]

What can I do now?

does your card have dual bios?

 

[Alt0153]

if no dual bios you need to flash it again using integrated gfx or a second gpu

Hat deine Karte ein Dual Bios?

Ja, Dual-BIOS. Aber kein Effekt, auch Black Screen.

Original-BIOS mit More Power Tool geladen und gespeichert, PC neu gestartet. Ohne Erfolg

 

[Cthulhu 76]

Wenn kein Dual-BIOS vorhanden ist, müssen Sie es erneut mit integrierter Grafik oder einer zweiten GPU flashen

den PC mit Hilfe einer zweiten Grafikkarte gestartet. Dann das alte Bios mit dem More Power Tool geladen, gespeichert und den PC neu gestartet. Aber die RX 6800 gibt immer noch kein Signal

 

[Thekwango]

Ja, Dual-BIOS. Aber kein Effekt, auch Black Screen.

Original-BIOS mit More Power Tool geladen und gespeichert, PC neu gestartet. Ohne Erfolg

stop using more power tool is your first step. follow the recovery steps for your cards bios from the manufacturers website is your second. pray is the 3rd!!

MPT does not write to the bios of the card it adds an entry either into the registry or the drivers. Load windows into safe mode and uninstall the AMD driver. Reboot pc and you will be back to normal. Hopefully you have not done any real damage. You will need after this to reinstall the AMD drivers again.

Absolutely correct, just writes power play tables to the registry, ddu or AMD clean-up will both work

MPT schreibt nicht in das BIOS der Karte, sondern fügt entweder einen Eintrag in die Registrierung oder die Treiber hinzu. Laden Sie Windows in den abgesicherten Modus und deinstallieren Sie den AMD-Treiber. Starten Sie den PC neu und Sie werden wieder normal sein. Hoffentlich haben Sie keinen wirklichen Schaden angerichtet. Danach müssen Sie die AMD-Treiber erneut installieren.

Thx my Friend. I will try it
