Good afternoon all,
Since the 11.8 drivers my Ati 5970 (a dual-GPU) has a fixed screen to overclock what is meant to be both GPUs at once, unlike all previous drivers that required you selected each GPU and set the clocks that way. There is no drop-down box to overclock each GPU. I am using the latest 11.10 preview 3 with CAP3.
CCC is meant to overclock my dual-gpu but leaves second GPU at 770MHz/1120MHz
The issue means that I've only found out that GPU-Z is showing the first GPU clocks to whatever I want it to BUT selecting the second GPU shows it is limited to 770MHz/1120MHz. Unticking Enable Graphics Overdrive does set the clocks the same defaults of 725MHz/1000MHz.
With MSI Afterburner I've tried to set both clocks the same but that only shows 1 GPU as being clockable, the other isn't showing any clocks. Unticking simultaneously GPUs to clock the same doesn't work.
Up until now, I've managed fine in achieving simultaneously higher clocks so why does the second GPU clock differently to the other (considering it is a dual-gpu)? And is there anything I can do to overcome this puzzling problem of the second GPU being 'stuck'?
Thanks!
