Right, flashed this bios this afternoon on both my Sapphire HD 5770's --flawless!

Finally got rid of a multitude of aggravating problems AfterBurner gave me after i changed "EnableUnofficialOverclocking" to "1" in the cfg file.

Problems like system hanging after making changes in AB, resetting only one card to default values or only applying settings to 1 card, etc.

The cards now clock over the 960 limit without a hicup.

I flashed the cards in crossfire config like this:

atifflash -f -p 0 unlock.bin then reboot with ctrl+alt+del, boot into windows, new device found. Checking with GPU-Z, yes, Asus bios.

Back into dos, typing this command: atiflash -f -p 1 unlock.bin , reboot, same thing...done!

Change the biosname to something short, "asus unlock bios.bin" was too long and not recognized by Atiflash. I named it "unlock.bin"

I ran 3 dm 06 at 1070/1350 this afternoon with 1.35V on both cards, watercooled.

My cards have Samsung memorychips, they max around 1350-1360MHz, i think the Hynix is much better.

what does "EnableUnofficialOverclocking" changed from "0" to "1" do?

[tbone8ty]

no i have a v1 xfx card.

edit, did a bit more searching and found that you can enable unofficial overclocking in msi afterburner that go past the bios limit. I am now running at 1ghz core 1.35 ghz memory at 1.25v with only 2c more of max temp at full load.

You just have to open the config file of arterburner and change the unofficial overclocking value from 0 to 1 and you are good. Dont need to flash the bios.

the only drawback is you lose powerplay and that mean it never get into its idle mode so if you bought it for the power saving, the afterburner unofficial trick is not a good idea for you.

ah ok i get it, i flashed my bios so i dont need to do this.

-------------------------

i did notice when i run default settings (no OC) in MSI afterburner it runs at 400/1200 or 400/900 when im in the desktop and rarely drops to 157/300

but when i overclock in MSI afterburner (1000/1300/1.25v) it runs most of the time at 157/300, hence the stutter and lines when im in the desktop(2D mode)

weird...

anybody experience this?

It enables you to go over the 960MHz CCC core limit.

I bought a sapphire card second hand came pre flashed with the asus bios and have problems.
In 3d mode the gpu clocks are stuck at 600 mhz and 1200 mhz memory no matter what I try even tried a reformat of win7 all sorts of drivers.

It's a real shame as I would have loved to have kept this card looks like not many with this type of cooler were made.

Anyone had a similar problem ? did a bit of googling and found a few people that had this 600mhz problem on stock cards but cant find any solutions.

[snoro]

that mean you got one of the wrong bios saphirre vapor-x hd5770. To solve that problem, you have to flash your bios to a normal one or you can just simply already get the asus unlocked one. It will sert back you stock spec at 850core and 1250mem and you will have unlimited overclocking limit.

[c64]

It has the asus unlocked bios on there.The stock for this card is 850/1200 it's not a vapor x.

Hey guys, I have a XFX 5770 rev 1 stock cooler. I use MSI afterburner to try 990MHz-1035MHz with 1.2V-1.35V voltage but it freezes after a few seconds when I running 3dmark 06 and vantage, it could not be stable even I bump the voltage to 1.35V and seems to get even unstable. I have tried my memory clock at stock 1200MHz and up to 1485MHz and I think it's not because of the memory. Also the load temp never goes up to 65C. Is my chip really a defective one? I can only pass 3dmark 06 on max clock at 985MHz, I also passed 3dmark 06 on 960MHz core on stock voltage (1.125V).

I have flashed this unlocked BIOS to my Powercolor 5770 PCS+ with success. However, I still can't enable the voltage control. I select enable voltage control in afterburner, but still nothing.

Is this feature disabled by Powercolor? Do I need to do something else to enable it?
