Radeon HD 6870 latest driver & bitcoin mining client

[Alpheus911]

Anyone here mine bitcoins with a 6870? Which version of the driver are you using? Just the standalone driver or through the Catalyst Control Center package?

I ask because I had no problem mining with the old version (not sure which one it was, may have been as old as March 2011) of the driver I had but the latest results in all kinds of errors. So I uninstall the new driver via uninstall of their infernal CCC package, and install an older driver via installing an older version of the CCC package, and now the miner doesn't work with the old driver either. I've tried 6 different old CCC versions and none of them work, some wouldn't install at, one BSOD'd me, while others returned an error with MMdriver.exe, whatever that is.

Any ideas on what's going on and how I can get back to the older bitcoin mining friendly driver I had?

Turn Off the antivirus and firewall, turn off the functions of windows defender.
If you have multiple security programs installed, they must be turned ALL off. Security will prevent your driver from installing...
After the AV and FW have been disabled, delete the current game and reinstall it.
Download the latest CCC driver package, and save it to an easy location. Make sure this is the correct driver for your card.
Set the font size to 100% if it has been enlarged, first. This is located in display section…control panel…
Delete all the current AMD video software and drivers, restart the system (the video will look screwy, don't worry) Now load install all the newest CCC drivers and restart the system (the driver will not work (yet) as you said, but load it anyway)
left click start
left click computer
right click C drive
Left click Open
Right click Users
Left click properties
"Check" mark the box that says: Attributes: "Hidden" (there is now a check-mark in the "Hidden" box)
Click: "Apply"
Now the system will apply the hidden attributes...and this will take a while, or maybe a long while. Let this proceed, and don't interrupt it...
During this procedure, a message may inform you that you do not have administrator privilege to the file you are trying to change the attributes of. That's OK. Just click: "ignore all."
When this procedure is finished, click OK (the box will close after you click OK)
Now you will once again be looking at folders in C drive (don’t close the C drive window or you may regret it)
(once again) right click Users
(once again) left click properties
UN- check the box that says: Attributes "Hidden" (you will now take the check mark OUT, Hidden is no longer checked)
Click Apply
Now the computer will UN-apply the hidden attributes, and it may take a while, or a long while...but let it proceed, and finish, don't interrupt it.
During this procedure, a message may inform you that you are not the administrator of the file that you are trying to change the attributes of. That's OK, just click: "ignore all."
When this is completed click OK
Now close all windows and restart the computer
turn all the security back on.
At this point, the CCC should be functional. Open the CCC and test the functions...
