The BIOS signature check is for Polaris GPUs. It has nothing to do with the R9 290.

RE: AMD/ATI Pixel Clock Patcher
I have a Rx 480 with a notebook vBIOS in my laptop while AMD does not seem to distinguish between the desktop and the notebook version, I tried using the atikmdag-patcher-1.4.6 to patch my Rx 480 with a modded vBIOS to unlock TDP from 75W to 110W with some other minor changes but the BIOS signature check patch does not seem to work, my operating system is Windows 7 Pro SP1 x64, not sure what I am doing wrong I uninstall the driver with DDU, restart, install the driver then patch with atikmdag and then restart yet I still get Error 43 in the system from signature check failing to verify.
Everything works fine with standard vBIOS's its only the modded ones.

So far I have tried the following drivers, ReLive 17.11.4, Adrenaline 18.2.1, 18.5.1 and 18.7.1, none of them worked the only on that did work was that 2 year old Crimson driver before they added the BIOS checker.
Any advise? I tried flashing the desktop reference vBIOS too without luck still same error, running the tool with administration rights, even tried turning off driver verification in W7 to no avail.

there is another limit apperently, how to remove it?

will test it soon on HD7950 and GDM-FW900

ps. those cards obviously do have VGA outputs but newer like R9 290X lack them and so to buy them I need some form of support. 300MHz limit would be more reasonable than 230MHz Sad

I've ordered a new GPU which doesn't have any of analogue outputs.
Would like to know if such converter can handle a 200Hz CRT.

RE: AMD/ATI Pixel Clock Patcher
Hi,
I have a problem with my R9 380 4GB the card was used for mining but after I put the correct BIOS on it it shows my memory and GPU clock speed at 0.
You say in you description to run "atikmdag-patcher.exe" where exactly is the exe file I can not see in the archive you've put for download.
Or is there a tutorial I missed on how to use the software?

Download: atikmdag-patcher-1.4.6.zip - Source: atikmdag-patcher-1.4.6-src.zip

A message from ToastyX:

Creating and maintaining software is a lot of work, and I have provided updates and support for free over the years. I would like to continue providing updates and work on new programs, but I need your support. If you find my software useful, consider supporting me through Patreon:

[Image: patreon.png]

As an incentive, I've added a couple of goals:
  • 1000 patrons - CRU: Add basic support for DisplayID detailed resolutions. This is required to support resolutions greater than 4095x4095 and pixel clocks greater than 655.35 MHz. I have completed this and released it as CRU 1.4 despite not meeting the goal.
  • 2000 patrons - Create a new program to force monitor resolutions using hotkeys. This will use new methods to change the available resolutions on the fly, making sure only the resolution you want is active.

Requirements:
  • Windows Vista or later
  • 5000-series GPU or newer
  • CrossFire requirements:
    • R9 285/290/290X/295X2 and newer cards can handle higher pixel clocks without CrossFire bridges.
    • Older cards require two CrossFire bridges if the pixel clock is greater than 300 MHz. This is only possible with cards that have two connectors. It will not work properly with more than two cards. Dual-GPU cards such as the 7990 will not work properly at higher pixel clocks.
Compatibility:
  • Version 1.4.6 is compatible with Catalyst 11.9 to Crimson 18.9.1. It can be used with future versions if it finds the limits you need.
Getting started:
  1. Run atikmdag-patcher.exe. (If you only need the BIOS signature patch, rename it to atikmdag-patcher-bios.exe first.)
  2. If all limits are found, click "Yes" to patch and sign. If a limit is not found or if multiple matches are found, the patcher needs to be updated.
  3. Reboot.
You can then add higher refresh rates using Custom Resolution Utility (CRU).

To restore the unpatched driver, run the patcher again and click "Yes" to restore from backup.

Unpatching is not required before upgrading drivers. Simply run the patcher again after installing the new driver.

Known issues:
  • Legacy drivers may have issues with HDCP and video acceleration with the patch.
  • Workarounds for video playback issues with legacy drivers:
    • Disable hardware acceleration in the Flash Player settings (right-click on any Flash video and click "Settings...").
    • Use the Codec Tweak Tool to disable DXVA hardware acceleration under "Various Tweaks" (in the "Miscellaneous" section).
  • AMD/ATI cards have a design limitation unrelated to the patch that causes video acceleration to scramble the screen if the vertical blanking/total is below standard with the video card's memory overclocked or with multiple monitors connected. Skype is known to trigger this problem. Either don't overclock the video card's memory, or use the "LCD standard" vertical blanking/total in CRU.
  • AMD/ATI cards require the "LCD standard" vertical blanking/total to reduce the memory clock when idle. Horizontal values can still be reduced if necessary.
Recent changes:
  • 1.4.6: Find new HDMI-DVI limit.
  • 1.4.5: Updated for 17.4.1. Find new DP-DVI/HDMI limit.
  • 1.4.4: Find BIOS signature check.
  • 1.4.3: Fixed HBlank limit for 16.12.1.
  • 1.4.2: Find 56 horizontal blanking (HBlank) limit.
  • 1.4.1: Fixed an issue that prevented the driver from loading correctly with earlier versions of Windows 10. This does not affect the anniversary update.
  • 1.4.0: Updated for 16.9.1. Changed the way the driver is located and patched. Replaced 640x480 limit with low-resolution limit. Fixed VGA limit for 32-bit.
  • 1.3.6: Find 10-resolution limit for Radeon Settings.
  • 1.3.5: Updated for 15.11 Crimson. Find 640x480 limit for Radeon Settings.
  • 1.3.4: Try to improve finding DVI/HDMI limit for newer drivers. Removed blue screen workaround for 14.6/14.7.
  • 1.3.3: Updated for 15.3. Fixed DVI/HDMI limit for 32-bit.
  • 1.3.2: Updated for 15.2. Fixed DVI/HDMI limit for 64-bit.
  • 1.3.1: Find 297 MHz HDMI 1.3+ limits. Run 3 times to properly repatch an existing installation.
  • 1.3: Removed blue screen workaround for 14.9. Fall back to self-signing if signing fails.
  • 1.2.7: Attempt to work around some antivirus false positives. Repatching is not necessary.
  • 1.2.6: Fixed AMD APP encoding for 14.6.
  • 1.2.5: Updated for 14.6. Fixed TMDS and VGA limits. Implemented workaround for SYSTEM_SERVICE_EXCEPTION blue screens.
  • 1.2.4: Updated for 14.4. Fixed SL limit on DL-DVI.
  • 1.2.3: Updated for 13.30 and upcoming 14.x releases.
  • 1.2.2: Find new HDMI limit for 12.9+.
  • 1.2.1: Find 400 MHz VGA limit.
  • 1.2: Test mode no longer required.

RE: AMD/ATI Pixel Clock Patcher
After modding bios and patching using this patcher in last few I can't remember how many driver releases there seems to be driver constantly reinstalling PciBus driver at every boot causing realtek driver to reset itself and not save EQ settings after reboot also changing default audio device.

Using DriverStoreExplorer I noticed there are 2 pcibus drivers 18.30.0.0 and 18.45.0.0. Maybe that has something to do with this?

Will there be an update to this patcher?

If you don't see the .exe file, then your antivirus is deleting it without telling you.
