I just received my new shiney hd 7970 through the "door" , set it up and it's running fine. I also have a HD 5770 that I was using with my (old) main gpu , for mining. Now, to get the HD 5770 to mine I had to install SDK 2.5 pack (rather just copy/ replace the needed files) to get it to send shares to the pool I am using. I just tried that , the replacing of the files, and the HD 7970 now is not detected which kinda makes sense.
My questions is if there is a work around for me to use both? or if it's impossible now for me to mine on both on the same PC.
thx!
SOLUTIONFirst, wipe all amd drivers/software using the amd software
Restart
Install the latest drivers (13.3 beta) and select custom, deselect SDK runtime but install everything else.
Restart
I used a SDK file pack i found on these forums,
http://dl.dropbox.com/u/9768004/AMD-APP-SDK-v2.5.rar. Open up the .rar file and copy the contents into the C: drive, overwrite as you go (might be worth making back ups to save the pain of doing it all again)
Install SDK runtime 2.5, custom , deselect everything and select SDK runtime and continue.
try 5770, wait for 1st share then close miner. (the new card will not show with 2.5, it did not for me)
Install SDK 2.6 runtime , custom , deselect everything and select SDK runtime and continue.
Test the 5770 again and wait for that first share.
Job done
