After having time to settle an an EK-FC7970 block + backplate added I am seriously NOT impressed with my Sapphire 7970.

Stock volts using ccc will do 1125/1525 no problem - HOWEVER I note a loud noise coming from the card when I overclock even the slightest - its more a electricity crackling noise than a cap whine! - Anyone else had this?

Overclocking wise using AB - I can get upto 1175@1.2v - and thats it - no higher Even with a waterblock it just refuses to go higher no matter the voltage.
