Temperatures and Boost Clock
The card boosts up to 1890 MHz if it is cool enough and the GPU load does not exceed 20%. However, this is a kind of fair-weather boost, which then collapses from 1800 MHz down to about 1785 MHz as the temperature rises in my very extremely demanding test game. Thus, it is still slightly above what NVIDIA also officially states for the boost. The memory can still be overclocked a bit, whereby the GDDR6X memory gets about 86 °C (Torture about 88 °C) warm inside. This is not little, but still harmless.
The GPU couldn’t even be overclocked more than 200 MHz stably, which then resulted in about 105 to 120 MHz more clock after warming up. Effort and benefit? Dog-tail principle, because more waste heat causes the boost clock to drop again. Here one will have to hope for the GPU lottery and the best possible manual voltage adjustment in the curve editor. Depending on the chip quality, this can even be worthwhile with this GPU
Now let’s move on to the recording with the high-resolution infrared camera. The PI640 from Optris has a true 640 x 480 pixel bolometer and records at up to 30 FPS. Here I use the normal lens and calibrated film with a known transmittance, so that I can de facto see inside the closed housing. The small hotspot on the backplate can be explained very quickly, because exactly there is a single small pad between the back of a voltage transformer row on the board and the backplate. That’s about as cool as you can get from the back, unfortunately.
I now remove the backplate and look at the circuit board. The bottom side of the VRM is relatively warm with up to 80 °C, the hotspot is located on one of the two input-side shunts. The rest is high at a little under 80 °C, but still in the harmless range.
