since i bought the Sapphire Vapor-X R9 290 OC i have problems with my memory speed. If the memory speed is on factory settings (1400 Mhz) i have artefacts all over the screen and the system crashes after a while. The strange thing is, that if i have a game running, the system is stable and no artefacts are shown! I should have returned the card but missed the timeframe for it
However, i could handle these problem by downclocking the momory from 1400 to 1365Mhz BUT since wattman was born, for whatever reason (maybe great manager descition ), it is not allowed to downclock the memory - only overclocking is allowed. The downclock could only be handled via MSI afterburner till version 17.7.2, now even with MSI afterburner is not able anymore to downclock and my system crashes constantly ...
As i can read i am not alone with these problems and the question is not answered or solved by AMD. AMD please be sure that my next graphic card will not be an AMD if you restrict the customer in this manner if they try to compensate your production chain failures!
I would be really happy if you could answer a solution or help us in any way to understand these restrictions!
