[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 515

post #5141 of 38701
Finally I'll be able to join this damn club I've been subscribed to since day one!

The 590 is sold and my 7970 will be ordered as soon as the payment has cleared. Just not sure which to go for! Probably a Sapphire reference considering the TFIIIs aren't out yet.

Man what a beast this card will be if this is true. Makes sense since they require less power right?

...or should I wait for a 7990! Sounds awesome.

What exactly do you mean "Unlocked"? Are most dual chip cards locked to a lower stat per chip?

Oh joy, the Windforce HD7970 I received today is making a very loud coil whine noise when playing games/benchmarking. It's as loud as a bee.

I plan to OC to max at possible so likely 1.2v+ for each card, and probably an overclocked ivy

I have a 2500k 5ghz and 2 7970's at 1200/1600 1.200v, 4 120mm fans and a 655 pump. With those clocks, I've seen 790w from my UPS while benching and gaming. I have yet to see 800w. I have a AX1200 so I'm fine, but you could get away with using a AX850 for sure and still have some reserve.

Don't waste your time with an RMA

Apparently coil whine is happening to a lot/most of people here. You will most likely just get a card back that does the same thing.
post #5149 of 38701
Well I'm not going to put up with it... I have a headset and it's still so loud. I may as well try my luck with another HD7970.

Fair enough, I wouldn't have thought it would be that loud.

Maybe you just got a bad one. Also its not covered up as much like the ref design, Maybe that is contributing.
