Enable OverDrive for AMD Radeon Mobile discrete GPUs in Catalyst Crimson Edition.

2017-01-20, 21:21 PM

Hallo,

 

I had a lot of stuttering with my Y700-15ACZ caused by a throttling Radeon R9 M385X while gaming.

So i installed MSI Afterburner and activated overclocking for the Mobile Radeon.

After that i was able to reduce the clocks with MSI Afterburner for constant framerates.

I saw that there was also OverDrive enabled in Catalyst Crimson Edition Control Center.

 

I sniffed for the changes of the registry while applying the settings in MSI Afterburner.

There is just one value added to the Registry.

You can paste this text into a textfile and save it as .reg file.

 

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]

After executing the .reg file you have to restart Windows for applying the chances to the display driver.

 

Now you can change the GPU frequencies without installing an application:

You can save a global setup or a separate setup for each game. Here the downclocking is applied when you start Star Wars Battlefront.

 

I am not responsible for any damage to the software or hardware of YOUR computer!

 

Best regards

Hi,

I've tried your .reg, it doesn't work (Windows launch repair tool after restarting) running Crimson 17.1.1 and Windows 10 x64 Anniversary. 

Did "Power Control" slider improve performance ? If yes, is it better when allowing more power ? Or less ?

Thanks :smileywink:

There is only a chip and mem frequency slider. Downclocking helped for smooth gameplay. CPU bottleneck makes the Y700 with AMD APU stuttering.

Add power slider could be very useful... We can tell this to AMD to get power slider implemented (-10/+10%)

Do you know why it doesn't work for me ? (repair tool)

Which driver are you using ?

I use this driver AMD VGA Driver for Windows 10 (64-bit) - ideapad Y700-15ACZ.

I have no idea why it doesn't work for you.

Are you sure that the boot problems have anything to do with this registry value?
