7970 Higher ASIC quality = Higher VRM temps?? - Page 2

I wonder if this theory is correct, as even having a Vapor-X card, which are notorious for bad VRM temps, mine is still awful with a card that can run 1200 at a pretty incredible voltage.
Well they say they are rated for 120c and some users have been unwise enough to let their go to 140c for afew minutes and still have a live card. So maybe that's why some GPU manufacturers don't care too much about cooling them well (as well as aftermarket manufacturers as i've come to learn the hard way redface.gif ) The MSI Lightning has excellent VRM cooling but the fans are noisy.

So i think they are pretty tough and can handle alot of heat, still though "i know that feel bro" tongue.gif i hate high temps and seeing anything running at 90c rustles my jimmies.

Perhaps you have trouble understanding what I quoted. GPU-Z has no way of measuring the CURRENT leakage, and so gives its rating based only on the stock voltage readout.
What Dave Baumann said, is that AMD is supposedly binning their chips the other way around in order to have the same TDP on all of them, even if it means for some to have an unnecesarily high voltage. It's pretty clear that chips with higher leakage require higher voltages, but this is not what is discussed here.

higher leakage parts use lower voltage and the lower leakage parts use a higher voltage

Yes. One is physics, the other one is how AMD bins gpus (supposedly). Think about it - there's only one way to have equal TDP on two chips with different leakages, and it is to run the lower leakage one with higher volts, even if it doesn't require this.

That's not what's happening lol.

Perhaps in your world, where amd drivers throttle furmark wink.gif

So you got nothing and resort to ad hominem? rolleyes.gif

You contradicted Bauman. What is this separation from Baumans coked world with the real world of physics?? Everything known about leakage is opposite to what he wrote. LMAO. Waste of time.

Thats what you're failing to understand. Baumann knows leakage. It's just the binning they do the opposite way.
BTW, most GHZ edition 7970 have asic quality of 60-70% - this is because these are the least power hungry chips (least leaky).
But believe whatever you want.

Lol higher ASIC use lower voltage. One of my card is 88% with 1.07 stock voltage. The others is 70 % with the common 1.17 voltage.

Its pretty easy to understand higher asic lower voltage. If you think otherwise then just go play tetris with an oc 7970

I'm feeling retarded now after this discourse.
