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.

It's the 6950 that can be unlocked, and even then it's only partly true.

You can unlock a 5850 to 5870 clock speeds, but NOT unlocking the shaders, as it is impossible.
There is no point in unlocking 5850 to 5870, as it only increases the clock speed, which you can already do in numerous OC software.
Now if flashing 5850 to 5870 can unlock the voltage, then that is a different story. But keep in mind that Sapphire 5850 Xtreme does NOT use the reference design, so you might brick your card.

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.

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.

Ok! Many thx!

When will be posible... we could reach 1000Mhz and 420Mhash/s!

Thx for all!

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

Can anyone have the solution?

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?

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.

Any problems with the cooling fan on this Sapphire 5850?

I have the exact same card from NewEgg and can only get 850Mhz out of it. My silicon bows to your superior batch Sad

Setup?

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!

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

Yes, it is the same Sapphire 5850 Xtreme you linked.

Holy smokes, is that an 5850 doing close to 400MH/s? Simply wow

Sweet. I've got three of those Sapphire 5850's on the way. Two will be here tomorrow.

Glad to see they are performing well!

How did you hit 900MHz core with the default voltage Shocked

My card only goes up to 830.

Which card do you have? Is it the Sapphire one I linked?

If this helped you out, be sure to send me a tip! 1GpdfxpUsSsBQPbK7rMPbLuZUYEzGQ4K4g

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

Right click on a video > Settings
