AMD rx480 power consumption fixed ?

That was just my theory on why some CPUs throttle when too much energy is ran through them I was not suggesting the CPU was causing issues with the GPU. I was just pointing out there are some reasons a chip might actually run slower with more voltage and until an electrical engineer gets on the forums and explains it, it will remain a mystery as to why, but we do know it happens.

Totally legit for the wrong reasons.

The card if left unchecked draws more power than the motherboard can provide.
This causes problems.

By putting a hard limit on the card, you reduce the amount of power it can draw. It still works at 100% without drawing the excess power.

It is a fix to make your card work fine at stock speeds, but not a solution to the problem in my opinion.

Actually all new boards CAN supply the needed Amps and Voltage the PCIe specs are 10 years old ad need to be updated to current cards. Here read Toms 2nd test. http://www.tomshardware.com/reviews/amd-radeon-rx-480-power-measurements,4622.html

Pretty much any motherboard modern enough to take advantage of the RX 480 shouldn't have an issue with this extra draw, at least not for the short term. AMD already said they would release a fix for it soon.

Ahh, why all the fuzz?
There are no real problem with this power draw on PCI-E buss. yes the card draw more than 20% of the standard and so what?
It will not burn your computer nor will it damage the buss.
Now, AMD has been very truthfully and transparent about this issue, very honest and in my opinion that is very good. It helps them to maintain a good reputation.

So what is the deal with all this? Nothing. A storm in a glass of water.
Best regards from Sweden

It's not a simple as "more energy = more power." I have ran into this many times OCing CPUs. One of my theories is that sometimes chips run better with lower power (sometimes even lower then stock) and the excess power being forced through the chip is causing unnecessary heat therefore the chip throttles, but I am no electrical engineer and I am sure there is an actual electrical explanation for this. It seems that the RX 480s that have been having power draw issues actually preform slightly better if you force there power consumption down to where it should be.

Think of it like this, If you force extra power through a vacuum, it gets faster, but if you force extra power through your TV will you get a better picture? No, the picture will stay the same... until something fries or melts.
