AMD/ATI Pixel Clock Patcher

[Tommywise]

Hi, i have same problem as guy above... i got error message: Failed to locate driver file

i did fresh install of Windows 10, all updates latest, i have RX 6800 XT with latest drivers, before installation of GPU i did DDU in safe mode, but still i have this error message and im not able to patch it.

So can you help?

But i wonder if i really needs it, because i have Corsair Xeneon Flex 240hz monitor through DP 2.0

at least that Bios signature check: what is it and is it necessary? Cause i normally use CRU but i have some problems with overclock my monitor,which i had not, now it behaves weird, so i thought its because of this ATI patcher isnt applied.

Any way how to manually use bios signature alone without ATI patcher?

Don't use the patcher if you don't know what it's for. There's no reason to use the patcher with your setup. The patcher does nothing for DisplayPort, and the BIOS signature patch is for allowing custom BIOS modifications with Polaris GPUs only.

Hello, I have a problem with the latest Amernime drivers, when trying to patch the bios the error appears "failed to locate driver file".
The error appears when trying to install the beta package drivers that are the most updated in amernime.
When installing an older version of those drivers the error does not appear. It must be related to the new drivers in the beta packages

The link to the beta driver on their site is broken. The patcher works with 23.9.2, which is the latest official driver that supports Polaris and Vega GPUs. I can't test newer versions because I don't have a newer GPU, but the patcher shouldn't be needed with newer GPUs anyway. The patcher is mainly for DVI and HDMI limits with older GPUs and the BIOS signature check with Polaris GPUs.

https://pixeldrain.com/u/YHgTxXfg after updating to AMD-Software-Hybrid-Edition-23.12.1-PVNFlex-Nebula-Native-DCH (Amernime drivers), latest atikmdag-patcher doesnt work anymore, i need to patch the driver because im using a modified bios (OC purpose) on my RX 550 4gb

23.12.1 has significant changes, so I would have to find all the limits again. Stick with the official 23.11.1 for now.

Does this work for mininum Pixel Clock rates? I can't really do 240p on my AMD GPU

No, minimum is normally 25 MHz for digital connections. 240p should be possible as long as the pixel clock is at least 25 MHz, but Windows will not list resolutions less than 480 lines even though they are technically available for programs to use.

Understood, thank you kindly

I see, is there any way to circumvent this in any shape or form?
