I refuse to believe that could solve anything, and I'm a hardware man tbh.
My agp card runs great at stock voltage. I gave up on over clocking about 7 years ago.
If only you could work out how much energy you've saved by not overclocking. I warrant it'd be worth a few centimes or whatever crazy currency you use over there.
It's more all the fiddle fucking around and lock ups I saved, tbh.
