indeed. it's currently the best $/MH card (beating 6990). 2 MH/1$

It is pitch black. You are likely to be eaten by a grue.

On a side note, to stop YouTube from downclocking your GPU, disable hardware acceleration!  Doesn't (well shouldn't) affect performance.

How did you hit 900MHz core with the default voltage Shocked
My card only goes up to 830.

I'm surprised you are getting this Mhash/s rate in Windows. If you were able to recreate these settings in say the latest stable of Debian or  the latest release Ubuntu x86_64 do you think it would be even faster?

If you could get the clock up to the same speeds then it should get at least the same speed or possibly better.

It's impossible with the Sapphire Xtreme this clockspeeds... Because we can't change the GPUVOLTAGE... can you?

MY setup doesn't reach the 920MHz... how you do that?

Thx for all!

I'm surprised you're surprised. I get 372 MHash at 930 MHz in Debian. If I could run at 1050 MHz like the other guy I should get about 420 MHash.

With the Xtreme version I can't reach 920MHz... because it doesn't allow change the voltage.

At the Sapphire page says that TrixX can do that, but it's false... I try a flashbios, MSI Afterburner, GPUClock, etc... and not... not posible.

Can anyone have the solution?

Thx for all

tl;dr (I'll get around to it Wink )

The 5850 can be unlocked to a 5870 with a simple bios upgrade. and I think they have a dual bios so you can't brick them either. best Mh/$ card for sure. if my cheap 5870 supplier sells out before I get my fiat sorted out I'll be getting a 5850 for sure.
