Kotz!
Follow these steps to fix the powerplay issue: I wish ati would fix this though because doing this is a pain in the *** and it MAY void your warrenty.
First download GPU-z 1.7
http://downloads.guru3d.com/GPU-Z-0.....html#download
This tool will allow you to extract your video card bioses..That's right your 3870x2 has two bios files!
When you open Gpu-z it will display your cards info. Next to the bios version number is an arrow. Click it and it will extract the first bios file. Save it to your desktop and rename it "backup0" or whatever. At the bottom of the tool it will give you the option of selecting the second card. Click the down arrow and select the second card then extract that bios to the desktop and name it "backup1" or whatever. Double check the two files: one should be like 44kb and the other should be 64kb. Which ever one is the 44kb file is the (slave) card which we will get into later.
Now that you have those files download the atibios editor
http://www.computerbase.de/downloads...i_bios-editor/
Open each file and change the low power 3d clocks. Make them the same as the high power 3d clocks. Also make the voltage the same. Do not change the 2d or startup clocks unless you want to for some reason. Also make sure your changes are the same for each bios ex. dont make one bios file have a low power 3d frequency clock 300mhz and the other have 400mhz. Save both files under different names like "card0" and "card1" because you want to keep your original bios files in case you screw up your flash. Remember "card0" should be like 44kb because its the slave card.
The bios editor you downloaded should contain the ATI Flash utility.
Next you need to make a windows boot disk in order to get into dos. After your boot disk is created make a folder called "boot" and place the "atiflash" application file in that folder along with the backup bios files and the modded bios files.
Get a pen and paper and write down all your file names from the "boot" folder including their sizes.
card0 = 44kb
card1 = 64kb
backup0 = 44kb
backup1 = 64kb
something to that effect.
Write down the following commands in sequence because you may have to reference them in a "blind flash" This occurs when you flash your bios incorrectly and upon a boot the screen goes blank but everything boots normal. Blind flashing involves booting from your boot disk and typing the commands without being able to see them. That is why you need to write everything down and have your backup files.
Next restart the comp and hopefully your boot disk should take you to the dos prompt.
You should see "A:"
(write down the following commands)
Type "cd\boot" then hit "enter"
Type "atiflash -ai 0" then "enter"
(this command will display the info of your slave card. Make sure file size is about 44kb)
Next type "dir" then hit "enter"
(this will list all the files from your floppy disk. Verify that the file names and extensions match what you have written down. Dos my have displayed the file "backup1" as "b~1". If you blind flash you will use "b~1". Also extensions are files that have like .rom or .bin attached to the name. Ex "card0.rom". If you have extensions then use them when flashing.
Type "atiflash -p 0 card0" or "atiflash -p 0 card0.rom" if you have extensions.
(remember card0 is the name of your bios file)
If the flash was done properly you should see at the end something like "10000kb writen" "10000kb verified".
Now for the master card:
Type "atiflash -p 1 card1"
If the flash was done properly you should see at the end something like "10000kb writen" "10000kb verified".
Thats it your done now just reboot and hope you dont need to do a blind flash.
If you have any doubts or if something is different from what I have written, do not proceed, rather write everything down and post it.
