Until 16.12.1 I had a stable system with GPU overclocked at 1040MHz and memory speed underclocked at 1235MHz.

Now moving from 16.11.2 to 16.12.1 , the system is extremely unstable and practically useless which is caused by the 'new' Wattman software replacing GPU overdrive.

It seems in the user interface, I just cannot underclock the memory speed. It is reset to the factory minimal 1250Mhz and can only be overclocked.

 

It is insane if you cannot underclock memory speed. I absolutely need to be able to move back to max 1235MHz at any voltage and GPU speed.

Can someone give instructions how to establish with Wattman an underlocked memory speed.

If this is a software design flaw, please fix in next release.

BTW no ReLive ever installed.
