Hardware information??  We aren't minds readers...

 

Basic rules:

Give your hardware specs when necessary (asking for support) and any other time where it may be beneficial to have them listed.

with SMBIOS set to iMac 14,2 it works.

So why are you trying to change it iMac 10,1 ?

Or you could:

1. Open Terminal
2. Enter this command (it is one line)
   
   sudo nano /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist​
3. Arrow down to where you see <key>ConfigMap</key>
4. Replace the board-id "Mac-F221DCC8" with "Mac-F2268CC8".
5. Save the file by pressing Ctrl+O, then enter.
6. Exit by pressing Ctrl+X
7. Rebuild the kernel cache using the following two commands in terminal:
   
   sudo kextcache -system-prelinked-kernel
   sudo kextcache -system-caches​
8. Reboot

because otherwise it does not work speedstep. And the video card has problems when the video goes into hibernation. Thank you

I solved it by changing cloverconfigurator with the "product name" value imac imac 10.1 and 14.2 in keeping the other parameters.

NO!

edit SMBIOS, not the System Kext 

<dict>
	<key>SMBIOS</key>
	<dict>
		<key>Board-ID</key>
		<string>Mac-F221DCC8</string>
