I got a new toy today(ASUS R9 290 DC2OC) and have been playing with for few hours now.
Having satisfied my need to test the cards capabilities I am now facing a problem quite opposite from testing performance.
I noticed that GPU tweak has option to adjust the voltage of this card and having no need yet for that much horsepower so I want to undervolt and underclock this card to allow my case fans run as slow as possible.
The problem is that when I drop my GPU and memclock and then voltage, at around 1.2V I start to get black screen issues. Screen goes black and doesn't recover until hard reset.
My understanding is that reference cards run under 1.2V 950MHz GPU clock so it makes no sense to me.
GPU-Z reports cards voltage at 1.1V but there is no change in that if I drop the voltage from GPU tweak.
This new way of voltage and clock control is completely new to me and I hate it
