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

I didn't ignore your post. It's hard to answer everybody

I actually asked for more information :

• Did you use Shader complexity 3 ?
• Can you take a picture of the VRM of your cards ? here is an example : http://mangafranceworld.free.fr/Divers/DSC00550.JPG
• Can you redo the same test and monitor the VRMA just as i did using RivaTuner, and post the screenshot ? The idea is to see if your card stays below, or higher than 82A on the VrmA. Another user did it on Page 10

If your card withstand the test, either the VRM stage is not the reference one (i.e. 4-stage, and not 3-stage), or you forgot to check the fullscreen checkbox Or it's something new !

I m pretty sure mine are both non reference.

My powercolor/gecube 4870 looks like this

and this is the sapphire one i have

I used complexity 3 on it, fullscreen, but i heard my fans kick up to 100% instantly. Not sure if i want to run it again, as I dont want to hear a popping sound in one of my cards, cant afford to replace them at the moment ^^. I think both these cards are 4 phase though.

Just tried to get the volt readings via riva. Might be because i m on windows 7.. but i dont get the option for any Voltage readings.. just fanspeeds and temps. Riva says the Volterra regulators are only on the reference design, so mine must both not be reference.
