AMD themselves have acknowledged that the problem exists and they are working on it

Yes, AMD sub reddit. They determined the issue that it was the GDDR5 memory voltage from the PCIE bus, apparently the die is running off the six and the memory is running off the PCIE. AMDJoe (AMD employee moderator) clarified. They also specified that a driver update would resolve the problem with no performance impact on memory.

AMD releases about two drivers per month as of recent for the past 8 months. I'd be surprised if they cut that back now.

You don't sound like a very informed person.

Im just pointing out how you first said the problem doesnt exist/has been debunked and then immediately post how a driver fix (and it remains to be seen if this fix will/wont affect performance) is going to fix this non-existent problem redface.gif

I've only stated that it's rumor until evidence, but the problem isn't quite the same problem. It's not melting boards that's one thing! The real issue is the overvoltage impact on overclocking which a german site test and is also located on Reddit. Undervolting actually gains performance for users. Several electrical engineers stated that most boards designed around the modern standard of PCIE 2.1 and 3.0 are well within the support of 7 amps while still being regulated at 5.5 amps. With the new drivers it should lower the temps giving even more efficiency and OC potential. I still wouldn't without a proper after market.
