Black Triangle Artifact on Sapphire HD 7970 at 1125MHz / 1575MHz

post #1 of 2
Thread Starter 
Hello Everyone I am having a problem with the New Sapphire HD 7970 when I increase the Clock Speed & Memory to the Max limitation Value in the ATi CCC overdrive program even though i set the power tuner to the max as well +20% its no use . still getting Black Triangle Artifact while playing BF3 & White Flickering Flash Screens when playing Skyrim mad.gif . when i run it at Stock Default Setting i don't have this really annoying issue thumb.gif .

I am using the latest Driver from AMD . and here is my PC Specs : -

cpu : i7 2600 , 4.1 GHZ
cpu cooler : cooler Master v6 GT
Mobo : Asus Sabertooth p67
RAM : 8GB Corsair Vengeance 1600mhz
GPU : Sapphire HD 7970 3GB Vram
PSU : Crosair TX850watt
case : Haf x 942

Any help or tips would be really appreciated .

Thanks

Entirely possible that your card just isn't stable at those speeds and stock voltage. Have you tried overvolting using MSI AB?

My reference Sapphire 7970 can only do a max of 1080/1500 at stock volts (1.112V for my card) so don't feel too bad smile.gif

Bumping it up to 1.170V (stock volts for a lot of people with 7970s) allows me to hit the CCC overdrive ceiling with ease - though the temps can get into the low 80s.
