Overclocking ZOTAC GAMING GeForce RTX 4070 SUPER Trinity Black Edition
To overclock the ZOTAC GAMING GeForce RTX 4070 SUPER Trinity Black Edition video card we are going to use ZOTAC’s utility called FireStorm. This utility was just updated to support the new RTX 40 Super Series of GPUs with version 4.0.0.020E.
The ZOTAC FireStorm utility allows us to increase the Power Target up by 10% from 100% to 110%, which gives us some power headroom on the video card. In addition, you can also increase the Voltage with this utility, up +100mv, but we found that wasn’t necessary, and just dug into the TDP, but the option is certainly there to get a bit more from the GPU if you want to push it, which is nice.
Our final stable overclock on the ZOTAC GAMING GeForce RTX 4070 SUPER Trinity Black Edition was the GPU at +250 and the memory at +1500MHz. This is with default, automatic fan control, no manual speed added. This results in a GPU Boost of 2725MHz according to GPUz, compared to the default of a 2475MHz boost clock. With the memory at +1500, this boosts the memory speed from 21Gbps to 24Gbps increasing the memory bandwidth from 504GB/s to 576GB/s. We can see what the GPU clock speed actually results in while gaming, below.
With the GPU Boost operating at the default 2475MHz, the ZOTAC GAMING GeForce RTX 4070 SUPER Trinity Black Edition runs between 2570MHz-2645MHz at default, while gaming, with an average of 2613MHz. Therefore, before even overclocking, the ZOTAC GAMING GeForce RTX 4070 SUPER Trinity Black Edition is boosting well above the default GPU Boost while gaming, the cooling and power delivery is very stable to allow this higher GPU boost.
When we overclock the GPU to +250 (with automatic fan speed), we can see that the GPU clock speed increases to 2840-2885MHz mostly, with an average of 2868MHz for our maximum overclock average. Therefore, compared to the default 2613MHz average, the overclock of 2868MHz average is a 10% clock speed overclock, and we also have the memory overclocked by 14%.
Therefore, our maximum overclock is: 2868MHz/24Gbps (GPU/Mem).
The impressive part of the overclock is this was all done with the fans on automatic, we did not have to increase fan speed, and yet the GPU still remained very cool. This keeps noise down, while also achieving a very high overclock.
FireStorm Utility
The ZOTAC FireStorm Utility allows you to monitor GPU Memory Clock, GPU Core Clock, GPU Temperature, GPU Voltage, GPU Memory Utilization, and GPU Utilization as well as fan speeds from an easy-to-view status window. It also lets you control fan speeds manually, or set fan curves per-fan and save and load profiles. With the SPECTRA RGB tool, you can turn off the RGB or control what it does, color, brightness, and speed.
