When a stable driver for R9 390x will be released?
Already has been. Based on the wealth of information you provided, we can't tell you if it's your system or not.
Are the voltages correct, especially 12v???
PSU: thermaltake sp-750p (750w)
SAPPHIRE Tri-X R9 390x
Is my psu appropriate for this graphics card???
My computer is resetting.
I'm using MSI afterburner to put the gpu at 1000ghz instead of 1055(sapphire standard). There appears to be stable now, but I'm not sure because I started to do this yesterday.
If that 12v reading is correct, it is not providing sufficient voltage and needs to be replaced.
Maybe you're right, but I saw this 11.63 on google images, and 11.75 too, which also happens here. I saw one 11.25 too, but this one i've never seen here, the minimum i saw on my pc is 11.50. I've never seen 12 volts or more on google images. So I think I'll wait amd launch better drivers before changing my psu. A lot of people are complaining about the R9 390 and 390x, as there had been complaints to the 290 and 290x.
For the game your having trouble with stability try deleting the xml file found in documents. For example in GTA V it's located in documents/rockstar games/gta 5 and is the only xml file at this location and is normally the bottom one , this stores the graphic settings and any custom kb/m settings you have made. It will clear old settings and generate a new file. It worked for me.....so far!
