To overclock today we are using AMD’s Catalyst Control Centre. The HD6990 is set to performance/’OC’ mode. It is also worth pointing out that overclocking these cards past 880mhz will require some serious case airflow and cooling. We used an open bed for our overclocking testing.
It seems our first sample from AMD is an unusual example of the HD6990, as neither of our HIS cards were artifact free past 920mhz. Memory limitations were similar to the reference card, peaking around 1425mhz.
lol, bet you wish they could run in a 3x 6x setup !
14,000 in 3dmark 11. I thought i was doing well, breaking 5k last week 🙁 I suck.
Wow. just wow. AMD are owning everyone this week……..
YAY! 48k in vantage. insane, this card just friggin rocks.
I wouldnt be getting all too excited just yet, Nvidia have yet to unleash the GTX590 which I would think might kick the 6990’s arse.
The nvidia architecture is slightly more powerful overall, but its all about temperatures, otherwise they would both slap three cores on a PCB and duke it out. its not quite that simple.
its actually a feat of engineering in itself that AMD got this crappy single fan to cool such a powerful card. I almost choked on my cornflakes when I saw that tiny red fan, used YET again.
Man I’d love four screens and two of these. Best start saving.
Oh yeah and a new psu
And a new CPU
Damn…..
Crazy frame rates, do we really need kind of power? Best game in months was dead space 2 and it could run well with a 6850.
Portal 2 should be the same….
Hey quick question. Whats this sticker over the bios switch, do you void warranty by running the card at full speed? Is it dangerous? I really really don’t get this…
hell when you limit an overclocked 12 core intel processor at 2560 then you know you have something special !
One thing is certain, you wont be running this setup on a 650W psu. I think a 1200w is a minimum for this setup. might get away with 1000w, but it would be rather highly loaded with the rest of the components in the mix.
That performance is just stupid. as in stupid good, not stupid sucky.
