I was thinking I should put together a small post on the problems us Sapphire 5970 owners have encountered with a fix that involves flashing the gpu's Bios.
I as many others owe much thanks to True_Gamer from Bit Tech forums for putting all his time and energy with Sapphire informing them all of the problems the 5970 had, and to come up with a fix for all the problems.
Note, please type in dos ATIFLASH -i before you flash the gpu, that will tell you what gpu is the MASTER and which is the SLAVE. Some gpu's have master as 1 and slave as 0... So please be sure and check before flashing.
Also it will be faster renaming the files to m.ac1 and
s.ac1

Here's the latest official (Not Beta) Vbios for Sapphire HD5970 OC.
IMPORTANT: Make sure you clear all Display drivers before flashing new Vbios. (I would recommend using Driver Sweeper). If you do not, then you will result in getting BSOD doing windows start up!! (I know this as I found out the hard way).
http://support.sapphiretech.com/archive/attachment/3109/131_634136893713165000.zipThese are just the Vbios only. You will need to download Ati flash tool here:http://www1.sapphiretech.com/global/lib_files/40.zip
To flash your card, type the following commands in pure DOS mode.
For those of you flashing a different branded card Please type this command first to tell you which GPU is master and slave by 0 and 1 (My Master GPU is 0 and my Slave GPU is 1. Some people have stated that other brands have the Master GPU as 1 and the Slave GPU as 0). atiflash -i
atiflash -p 0 C0001OCM.AC1 -f
atiflash -p 1 C0001OCS.AC1 -f
Make sure you include all spaces/dash etc.. as shown.
For those of you that are unsure how to make a DOS bootable disc, please download this linkhttp://www1.sapphiretech.com/global/lib_files/103.zip
Feel free to leave +REP for helping you guys out.
Cheers,

For those of you using a waterblock here's a Pre OC vbios for the HD5970
You will need to uninstall all display drivers before flashing this OC vbios. Overwise you will get a BSOD.
I would not recommend using this vbios if you are not using a watercooling block!
overclocked 5970 v126 vbios
For those of you flashing a different branded card Please type this command first to tell you which GPU is master and slave by 0 and 1 (My Master GPU is 0 and my Slave GPU is 1. Some people have stated that other brands have the Master GPU as 1 and the Slave GPU as 0). atiflash -i
(m) for master (s) for slave vbios.
Put these 2 files on your dos enabled usb stick along with ati flash tool.
Now type the following commands
atiflash -p 0 m.ac1 -f
Then after that bios has flashed type;
atiflash -p 1 s.ac1 -f
Now reinstall CCC and check GPUZ to make sure your clocks are running at 950/1200 1.2v VDDC 1.15v VDDCI
You may get a CCC warning saying your display drivers are _______? Just click ok and have fun.
Here's another Pre OC vbios 900/1200 1.175v VDDC 1.15v VDDCI

Master vbios
atiflash -p 0 9001200M.AC1 -f
Slave vbios
atiflash -p 1 9001200S.AC1 -f
Here's another Pre OC vbios 800/1100 1.15v VDDC 1.15v VDDCI
For those of you flashing a different branded card Please type this command first to tell you which GPU is master and slave by 0 and 1 (My Master GPU is 0 and my Slave GPU is 1. Some people have stated that other brands have the Master GPU as 1 and the Slave GPU as 0). atiflash -i
