--- Comment #11 from Elmar Stellnberger estellnb@elstel.org --- For the R5 230 long time experience is already available. I am successfully using this card at least since February 2016 at a TMDS of 297Mhz and these cards are doing very well on basis of everyday use as well as occasional full throttle.
