NVIDIA TITAN V: Overclocking, Power, Heat, And Noise
We also spent a little time overclocking the NVIDIA TITAN V to see what kind of additional performance it had left under its hood. To overclock the card we used the latest version of EVGA's Precision app, which has proper support for the GV100, and kept things super simple.
We've only had the card in hand for a very short time, and wanted to get this article posted as soon as possible, so all we did to overclock the TITAN V was crank up the power and temperature targets to see how it affected the GPU frequency.
Right out of the box, the TITAN V will actually hit its default power and temperature targets while under a sustained load, which causes the card to quickly bounce in and out of boost states. Its default boost clock is 1,455MHz, so simply increasing the power and temperature targets unlocked quite of a bit of frequency. We saw a peak GPU clock of 1,815MHz, which is quite a significant jump without touching the offset frequency. Even with additional cooling and frequency manipulation, however, we suspect the TITAN V will be power limited -- as you can see, we hit the power limit even with the target maxed out. We have to do some more experimenting here.
We also monitored system power with the TITAN V installed under a variety of other conditions. The overclocked gaming workload resulted in the highest power consumption, but all of the compute workloads resulted in significantly lower power utilization.
We should also mention that noise on the TITAN V is a non-issue. Even under a sustained load, the card sounds and behaves much like a TITAN Xp or GTX 1080 Ti, which is to say its fan does spin up and become audible outside of a chassis, but it is not loud by any means. GPU temperatures on the TITAN V aren't really a concern either, but the card will hit its 82 degree temperature target under load with the default fan curve.
