I got a sapphire dual x r9 270x from ebay cheap(~$70) and it has artifacts in torchlight 2 and marvel heroes 2015 when set a default clock speeds of 1070hz. Also get lots of errors in OCCT when at stock speeds.
I can alleviate these by reducing the clock speed to ~950hz, but was trying to figure out what else I could do to address these issues and get it to run at factory clocked OC.
Unfortunately I cannot RMA it because I bought it used, so I am trying whatever I can do otherwise.
