Thanks. I also have another question that's unrelated, but I'd rather not clutter up the forum with a new thread, so I'll put it in here.

I'm running a nvidia GTX460 for mining under ubuntu, and I'd like to overclock it. I read that setting the "Coolbits" option correctly would enable this, so I read through the documentation to figure out how to set the option to enable fan controls and overclocking. Apparently, lowering the clock rate is supported, but raising it is not according to both nvidia's documentation, and screwing around with the configuration utility provided with the driver. Does any one here know of a nvidia linux driver that does allow overclocking? That would be much appreciated.
