Temperatures & Clock Rates
Overclocking the ROG Strix GeForce GTX 1080 Ti 11GB OC Edition yields moderate gains, so long as you're willing to tolerate the fan's 3500 RPM maximum speed.
While the silicon lottery plays some part in each board's available headroom, it's always going to be difficult for GP102 to hit 2.1 GHz on air. Even if you are successful, maintaining stability at that frequency is exceedingly difficult.
It's possible to dial in slightly higher clock rates from the GDDR5X as well. Just be careful, because those modules get pretty hot when they're overclocked.
Temperatures & Frequencies
The following table includes starting and end values for our temperature and GPU Boost clock rates.
|Start Value||End Value|
|Open Test Bench|
|GPU Frequency||1962 MHz||1873-1887 MHz|
|GPU Frequency||1936 MHz||1860-1873 MHz|
|Temperature Inside Case||25°C||41°C|
|OC (Open Test Bench)|
|GPU Temperatures (3550 RPM)||28°C||63°C|
|GPU Frequency||2012 MHz||2055 MHz|
Temperatures vs. Frequency
Here's a closer look at the data over 15 minutes, during our sample's warm-up phase.
Infrared Temperature Analysis
As the pictures show, the area around the VRM and memory modules gets very hot. Over time, this thermal energy spreads across the board towards the GPU, heating up the memory modules in its path. This could have been addressed using direct cooling with a VRM heat sink.
