Hello, I've dicovered that with ATi Tray tools I can set lower GPUcore voltage 2D setting vs PowerPlay that can't set lower of > 0,950v. For example, at 150/300MHz I can set the vGPUcore at 0,875v. C:\Users\<username>\AppData\Local\ATI\ACE\profiles.xml works on 3D mode (1,75vcore vs 1,88v for example). I've an non-reference Toxic. Can the developer/s tell me how works this program for set vGPUcore? Change registry keys, or low level request to the driver? I like to found an workaround for 2D lower vcore settings.
