This worked and I am now at 685 memory clock and 1050 gpu clock with a good temperature and 630/Mhash per card. Thank you much. I learned a bunch and now feel much more comfortable. I am going to work on more tweaks and I'll post updates if I get anything note-worthy.

Topic: Help: Lowering Voltage on a 7970 (2 card) in Windows 7 (32 bit) (Read 1408 times)
Have you tried Sapphire Trixx 4.3.0? It (should) support 7970 since 4.3.0 came out and specificly noted 7970 being supported..
You also might want to venture into bios modding, see how that works out.. but RBE hasnt been updated in a long time, makes me wonder if 7970 is supported.. Seems RBE doesnt support 7xxx. Author doesn't want to put in the effort to update. Lazy fuck. Us bitcoin miners should all beg him and throw money at him, maybe he'll update then,
You cannot change the voltage in CGMiner nor will it show the actual voltage correctly. Make sure you're using MSI AB version 2.2.1. You can verify everything in GPU-Z as well.
To lower the memory clock, open up MSIAfterburner.cfg with Notepad and change UnofficialOverclockingMode = 2. Then reopen AB and lower your memory. After that, close AB again and go to MSI Afterburner\Profiles and delete anything that starts with "VEN_". Open up AB again and you should be able to lower it even further.

I am close to finally having my specification to where it needs to be. The last item that is giving me problems is this:
I can not seem to be able to lower the voltage in a windows 7 (32 bit) environment. I am using CGminer and Catalyst 12.3 with no afterburner. I did have AB on it before but when I lowered the voltage, it never actually changed with the GUI interface. Is there a special order of operations or a certain way I need to do things to get the voltage down? The same goes for lowering the memory clock as well.
Suggestions? (People with 7970s only please)
