		+	Note on boost: We cannot go above the frequencies set by nvidia-smi (no further overclocking) unlike the GeForce card. Reason being (From NVIDIA):
		+
		+	<i>The clocks on Tesla GPUs cannot be adjusted beyond what is permitted via nvidia-smi.
		+
		+	Some background on why Tesla clocks are set lower than similar GeForce cards which may help in discussion with your customers. The physical characteristics of silicon change over time, and change more rapidly at higher temperatures. GeForce cards are expected to be used a few hours a day with a short operational life as the gamer upgrades to a new product to play the most recent games. Tesla GPUs may be in operation 24/7 over several years. We need to guarantee that the product is still within spec for its whole operational lifetime taking into account the physical changes to the silicon. Also we work with OEMs to certify the products at particular power and thermal settings.</i>
