4870 ASUS TOP BIOS (upto 900MHz in CCC)

Everything with atiflash happens in true DOS only, you cannot run/flash using this utility inside Windows.

is it recoverable any more ?

It should be, flash from DOS, real DOS not Command Prompt from Windows.

Well the picture of Command Prompt shows your not even in the proper directory.

can you help me out then and tell me the right commands? I run out of ideas!

In your Command Prompt window it shows you are in the directory,

C:\DOCUME~1\M-XXXX>

From here type,

CD Flash

Now you should be in the proper directory and can use Atiflash,

atiflash -p -f 0 4870.rom

Having said all this the flash should go OK but atiflash should really only be used in true DOS, not the Command Prompt way that you are attempting.

Thank you for all your help. In the end I flashed from DOS (thank you for advice) I had some problems with booting from USB, so I asked for instructions in windows flashing). In the end I booted from USB and the think was done in 10s!

Has anyone changed the core voltage through bios flashing? I think you can squeeze a bit more voltage out by bios modding the 4850, is the same thing possible with a 4870? Either way, what are your maximum core overclocks with bios volt mod/ no mod?

I ran my flash from an Administrator level command prompt in Vista x64, with UAC turned off, if anyone thinks that may be related to why most have issues with usint atiwinflash.exe. Just tossing that out.

i think 1.263 vGPU is as high as you can go through BIOS but i'm not sure. i'd love to be corrected by anyone who knows for sure.

i'm not game stable with the default settings on the TOP BIOS. i've lowered the clocks on both my cards to 750/900 while i contemplate what to do next. i really don't like the idea of volt modding my cards because i know i'll end up selling them within a year.
