Dude this is very cool of you, could you please run a 3dmark06 and post the results? Can't find this info anywhere.
 
I was really wondering why no one else was doing this. Sure, real game benchmarks are better but for those who want an idea of how it'll play any game these really help.

I am downloading 06 now :D
 
Thanks bro you rock. 20k on 3dmark06 makes this a gaming beast. I will be ordering one soon off Amazon.
 
2011 iMac with i7 3.4Ghz and HD6970m with 2GB VRAM,
overclocked to 710Mhz using MSI Afterburner:

3DMark06: 21220
3DMark Vantage: 13306
3DMark11: 3265

According to 3DMark, the CPU however performs slower than other i7-2600's.
So if this could be fixed by some firmware update (maybe it's the new Z68 chipset that's limiting the cpu?) to achieve it's full speed these score could even become a bit higher.
 
how did you do this ?

just ordered one of these...

how did you go about overclocking it and does it run ok?

thanks

You use MSI Afterburner, and it works perfectly.
As long as you don't play any games, the GPU will run on 100mhz natively (to save power and heat).
But when you start playing games or a program is about to use the GPU it'll crack up to the amount of mhz's you put in (or the standard 680mhz when you don't overclock it).

Only MSI Afterburner's temperatures are wrong.
But just turn temperature monitoring off. The iMac will boost the fans itself when it gets hot.
By the way, unless this overclock, it doesn't become much hotter then usual. MSI Afterbruner limits overclocking to 710mhz.
 
Please, does anyone got Vantage results for the 2011 imac with i5 and Radeon 6770?. I can't find any bench out there. Thank you.
 
I'd just like to point out that Saphire Trixx is a far better overclocking suite for this GPU. You can ramp it up to 800 with zero problems as long as you up the fanspeeds and keep the voltage steady.
