In first Place many thanks to Luc Verhaegen, for his work, and for the Open Source Vision.
I do remember some historic moments, and I do love history..love to read about all aspects of it.
Thanks also for that..

A low power in the APUs maybe...
Because desktop parts in Low Power mode suck ~32 Watts of power...more than several cpus at full throtle..
If that is true, that 2200G are Polaris based...
That would explain the HUGE power consumption of the 2200G in idle mode...Last edited by tuxd3v; 22 October 2018, 11:31 PM.

The current driver approach for OC is joke (only +3%) and for UV it is broken / not working.
Thanks to Luc libv for making a first step here in the right direction.

On the pre-gcn cards it's useful for changing voltages, timings, clocks for under/over clocking. I never tried it on a newer card tho, so I have no recent experience.
EDIT: Then of course there is this too....

As I said before, you don't need the vbios since the driver is open source. The driver just reads the values out of the vbios data tables. You can make any changes you want in the driver directly.Last edited by duby229; 23 October 2018, 01:13 PM.
