Hmmm, interesting thought! I tried underclocking it from 450 MHz to 400
MHz, but got another freeze not too far in. So I'm tending to think this is
a nvidia driver issue. (happy happy joy joy... why did I buy this card
again?)
Actually, second thought... did you underclock the GPU, or the memory?
I've been focusing on the GPU, maybe I should underclock the graphics card's
memory?
I'll have to do some more playing around, see if I hit pay dirt with
anything.
