Automatically adjusting GPU clock by temperature

2011-07-12 09:34 by Ian

My friend and I have built a BTC mining rig named hurrMiner. It contains two Radeon 6990 graphics cards that run very hot (~95C). Apparently, there is a thermal shutoff hard-coded onto the card, but we really don’t want to let the GPUs reach that point. What follows is my documentation for a script that will monitor the temperature of each GPU and adjust their clocks to approach a given target temperature.

Below is a live temperature graph of the GPUs in hurrMiner over the course of 15-minutes, 1-hour, and 24-hours.
