: Ok, in that case your chipset allows for lower clock speeds, interesting. We'll discuss this with AMD shortly, maybe we get some more insights. Maybe we even find out what the lowest possible speed is.
I've actually been running with memory clock of 250kHz and engine clock of 150kHz on my RV770 for some time. Engine clock at 100kHz seems to be fine as well.
I assume you're talking about MHz ;-)
Um, indeed. ;)
Memory clock settings might be interesting to set, but we have to blank the display when setting them, so this is nothing to set often. Unfortunately, because with DDR5 RAM this gives you the biggest savings according to my meassurements.
It also affects performance quite a bit, especially for Xv. Probably only reasonable, by default, to downclock only when in a low DPMS state. -- Yang Zhao http://yangman.ca -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
