I'm currently running 2 6950 MSI TF3s (
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127575&cm_re=msi_6950-_-14-127-575-_-Product) in a crossfire setup and am trying to find the best way to under clock them inorder to keep the heat, power, and noise down as much as much as I can. I haven't been able to unlock these cards and I can't figure out how to change the voltage or what to do with if I could change it. Mine on both cards when I'm not at my computer, only 1 when I go on youtube/movies, and turn it off during games.
I don't know if there is some ratio I need to follow as to under clocking the memory or the core. I just don't want to damage these cards
that much.
TLDR: How can I underclock/undervolt my 2 6950s to keep the temps and fan lower?
