Future versions of RBE will support importing and exporting method one overdrive hack signatures. With this, you can load a BIOS with increased overdrive headroom, save its signature to a file, open your original BIOS and import the increased overdrive signature.
Your advantage is that from now on, you don't have to wait for me to release a new RBE version to use a new signature from some BIOS that has just come into public.

For example:
RBE v1.14 supports a 4850 signature that increases overdrive to 720 MHz. A few weeks ago, the Gainward 4850 Golden Sample was released which included a signature for an overdrive maximum of 750 MHz. I added it to RBE immediately, but wasn't ready to launch a new RBE version yet, so people couldn't make use of the new signature.
From RBE v1.15 on, you won't have to wait for a new RBE version to use a new BIOS' signature.

Maybe you would like to share a signature you found or ripped off some BIOS somewhere. In that case, this thread is perfect for you. I will make the beginning with some interesting signatures I collected so far. But there are many other interesting BIOSes in the TPU database as well at MVKTech.net. So if you find a nice overdrive signature in one of those BIOSes, just post them here. :)

Please note: You should still use a 4870 signature with a 4870 BIOS only and so on. Don't get the video card types mixed up.

the asus TOP buios dont work on my VT hd4850 :( nor does the TOP for the 4870 on my sapphire 4870 :( :( in fact I had to rma the 4870 cuz it could not recover from the flash, I tried for days but gave up, the 4850 flashed back to the orig. bios first try, but something to do with the way the 4870's are made i gues, and I did try W1zz's 128k bios fix but still nothing :( :( :(

I just used the option in the new RBE v1.15.
I didn't have to add any signature

Im having problems getting stability after using the injection. Could you please edit this bios

http://www.techpowerup.com/vgabios/17213/Powercolor.HD4850.512.080605.html

so that at 3d clocks you get 1.158v and the asus top signature.

I've tried changing the voltages of 3 and 7-9 to 1.158v and then using the signature built into RBE for the hd4850. But doesnt seem to work.

Ive been using various edited bioses all this time editing those fields 3 and 7-9 and its been working fine. Ive had my card upto 835mhz/1150mhz with voltmods for benching purposes and it was fine with catalyst 8.7 and earlier.

But with CCC drivers 8.8 and 8.9 I can't use any edited bios which suggests my editing has always been wrong some how and AMD have updated CCC so that they don't work correctly together.

The AMD GPU tool ignores the limit placed in the BIOS to make testing easy and fast, then I plan on using this to upload a custom BIOS.



Excellent work BTW, I have used this too many times.

hm, and what abot making a signature with 800\\1000 not 1100, my 1gb sux at memory overclocking(((
Feel free not to use all the headroom provided. You're not forced to push it to the limit... ;)

What GPU Tool does has nothing to do with Overdrive. I'm afraid we can't gain anything from this. :(

heh, found an appropriate signature in o\c powercolor 1gb bios;)
Then post it, please! :toast:

/edit: Do you mean this BIOS?
