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

As a developer of both general purpose and DirectX applications, I've got to say that a lot of you guys are very frustrating with your assumptions about engineering and 3D programming. =/

As for my bit:
If the card can be made to draw current in excess of either its supply capability or its current protection threshold using nothing other than normal API commands, there's a design problem. There's nothing wrong with the chip, so maybe the title of the thread is misleading, but the reference cards' power supplies need some work. That being said, this was probably an intentional action. It makes sense to aim for above the middle as it'll provide compatibility with real life games. Making a design that is good for the upper 1% of applications that aren't widely used at an extra cost doesn't make a whole lot of business sense.

Well hopefully this doesn't extend into the future. Because as hardware becomes more generalized the idea of limiting the scope of "normal applications" will go away. There's no such notion on CPUs and soon won't be on GPUs either.

i Dont know if it helps u but here :

This was done with a newer Version of Powercolor HD 4870 1GB PCS
800/925 (stock on new revision is 780/925)
BIOS 02/24/09 21:07
ATOMBIOSBK-ATI VER011.013.000.002.000000

Like u said before ,no Blackscreen

But i have the same Powercolor with old Revision,i´ll test it in the next half an hour.

Now this was the older Revision
800/925 (stock)
BIOS 09/04/08 04:35
ATOMBIOSBK-ATI VER011.010.000.001.029909
Wekiva RV770 B50702 Board

Instant Blackscreen after the Donut comes out
