Black screen issue is not something new for Hawaii, my prime suspect for it is the memory controller because for some odd reason it's very sensitive to core voltage. My previous MSI TwinFrozr 290 gave me headache where I can't even undervolt more than 12mV without it getting black screened, my current 290X is more stable, undervolt 37mV no problem at all (both at it's factory clockspeed). On 390/X where they boosted the memory by 1GHz more than 290/X it's not going to be pretty. When I overclocked my card to 390X speeds, some time it worked with 38mV voltage increase, some other time it black screened and need 50mV to be stable.
For Hawaii, memory voltage is tied/related to core voltage. My card is stable at 1030/1250 stock clock with -67mV but the moment i increase the memory clock to >1300mhz, i get instant black screen. If i used the card default +13mV, i have no trouble increasing the memory to 1550mhz.
Guys, a quick one here. It's been ages since I've used an AMD card, moreover now with a Displayport connection. In CCC, is there any setting that I should enable in order to get a full color range? Somehow, I feel the colors are a little washed out at the moment. I noticed something similar on my Nvidia cards and I simply need to enable Dynamic Range to Full (0-255).
does AMD driver have no issues with RGB 0-255? Does it detect your monitor as LCD TV or PC monitor?
Because nvidia haven't fixed this yet. When you hook up your monitor through hdmi, the RGB will be limited to 16-235. As this is the default standard for HDMI devices. Normal for LCD TV.
By default it will use YCbCr 4:4:4. (or RGB 4:4:4: Pixel Format PC Standard (Full RGB) in some beta driver i've used)
