Unfortunately when using the Catalyst Control Center we are limited to 850mhz and we wanted to try and push the card further. We therefore decided to try the new beta of the Sapphire TriXX software which worked great, even allowing us to increase voltage to 1300.
A quick overview of the XFX Black Edition shows that the card fan is set to 53% out of the box, around 15% higher than the reference solution we reviewed last week.
Raising the card voltage to 1300, we managed to squeeze an incredible 1025 mhz on the core and 1175mhz (4700mhz effective) from the memory! We were stunned to see 1ghz+ on the HD6850 core less than a week after initial launch.
A whopping 2,500 point increase in 3DMark Vantage after our overclock, pushing the HD6850 Black Edition past the MSI Talon Attack GTX460 performance levels.
A six frame per second increase in Unigine Heaven Benchmark is a huge increase, reflected with the massive overhead via this particular core.
Shit on a stick, thats insane clocks man!
Ohhhh lovely. their modded cooler is good. shame its a tiny bit louder, but we can forgive it with those insane clocks.
ill buy a few of these I think for christmas 😉
First HD6850 over 1ghz, very sexy indeed. XFX are really taking it to Sapphire lately.
Heh, this is the start of extreme solutions. I can predict some amazing overclocks before christmas.
Absolutely stunning card, hope the price isnt much higher though.
I am not that interested in the core clock increases set in the bios, the potential overhead is what I love about the black edition boards. they have been doing this for years really and im stunned they got a 6850 black edition out so early. nice scoop KG.
Its AMD lovin on kitguru 🙂
Have to hand it to XFX< they are showing their worth as a partner for AMD. nvidia must be crying into their cornflakes.
cocks.
oh, this will make a nice christmas present, I just need to persuade the missus to fork out for it. fat chance.
Damn it, I wasn’t expecting this so quick. XFX got the edge on Sapphire.
but for how long? 1.1ghz possible before christmas? I think so.
XFX + AMD = Great Combo
XFX – NVIDIA = All 4 AMD
NVIDIA You Where Stupid To Let XFX Go As A Partner
To all the dumbasses saying Nvidia dropped XFX;
Get your bloody facts right – XFX dropped Nvidia when they made the 400-series cards.
