OCCT 3.1.0 shows HD4870/4890 design flaw - they can't handle the new GPU test !

DAMN thats hot, I think you just got lucky, those vrm are cooking and I think you just got cherry picked vrm that can handle the heat.

they've been quite a bit hotter for longer : P

Did you run the test in FullScreen mode ?

Your VDDC max stayed below 82A, that's why you're not experiencing the issue.

The 82A limit seems to hold true so far...

PLEASE NOTE THAT IN THE STABLE VERSION, SHADER COMPLEXITY 0 IS SELECTED AS DEFAULT IN OCCT. YOU HAVE TO SELECT COMPLEXITY 3 MANUALLY, AS OPPOSED TO THE RC1, WHICH AUTO-SELECTED "OPTIMAL"

yes it is full screen and yes 3 is selected.
after playing around i am able to recreate the black screen issue. by going into the driver settings and taking the anistropic filtering off of forced 16x and on to "use application setting" it will produce a black screen/freeze everytime for me. changing any other setting to application setting causes no issues.

i'm certainly no expert but this would seem to imply that it is an application issue would it not?
