All 4 of my 3780 Sapphires when i had them passed OCCT but my 1900xt Master does not.
Well ATI later implemented driver changes, so that when OCCT or FurMark is run on any 4xxx card and older, that card will clock down to stop it crashing. It will still use more load power than any game though.
Although with the latest drivers and OCCT version 4xxx series cards still instantly crash.
