Sapphire recently updated their excellent TriXX software to support the HD7970 hardware. We used it today for our overclocking adventures.
We used TriXX to increase the core voltage to 1275, which allowed us to overclock the core by a whopping 25.3 percent to 1253mhz! As we mentioned earlier Sapphire have paid close attention to the cooling of this card, placing heatsinks on the memory. This helps push the 3GB of GDDR5 memory to 1,542mhz (6,168mhz effective).
These overclocked figures are the highest we have recorded yet, from any HD7970 solution.
This huge overclock pushes the Sapphire HD7970 Overclock Edition well past the GTX590 and almost to the same level as the last generation HD6990. The HD6990 only scores 81 points more. This really is an incredible result thanks to the class leading cooling solution Sapphire have implemented.
awesome. im sure the price is nice too :p
They have been releasing good cards for a while now, those new coolers and fans are great.
Much as we would expect from Sapphire. dont see any stock anywhere yet sadly.
OMG, this card is a MONSTER, I cant believe it slaps the nvidia GTX590 around like its nothing, OMG – OMG, nvidia is in big trouble if this card is coming around nvidia`s release, i feel sorry for all the nvidiot fan boy that gonna get butt hurt… why sapphire, why?
Great card, but I prefer the appearance of the XFX cards. they just look better with that metal cooler.
that overclock is f&*king wicked.
How do you switch between the two bios settings? Is it complicated? Thanks!!
Hi Ryan. Next to the crossfire connectors is a little switch. Power the system down, flip the switch. reboot.
Done.
wonder what’s the vrm temp after overclocking with added core voltage? thanks…
