Looking at the factory settings of the MSI RTX 2060 Gaming Z it boasts of boost GPU Clock of 1830 MHz.
Thanks to Nvidia’s GPU boost, we actually see the RTX Gaming Z boost 120 MHz more settling at 1950 MHz.
We are going to start off by using MSI Afterburners built in OC Scanner. This will run the card through a series of tests at 4 different voltage levels to determine its best clock speed at a given voltage.
When running the OC Scanner, we did run into a few issues with it locking up our system and not recover. Luckily this only happened with the first two voltage level tests and after a reboot, it was able to resume the scan at the next level. Once we completed our scan it gave us an average overclock of 56 MHz with Power being our limiting factor. I also successfully tested the overclock by using the built-in test which passed with a 90% confidence level. After doing some research we found the 90% is the best score you can achieve with this test.
With the new “Curve” overclock applied and our power limit maxed out, we now see a peak clock of 1995 MHz. You will notice that we didn’t touch the core voltage as it seems to have no effect when trying to achieve a better/stable clock on 20 series cards.
Running Timespy we see a total score increase of 80 points and a graphic score increase of 103.
Since the OC Scanner only adjusts your core clock, we can still push the RTX 2060 Gaming Z a little further by overclocking the memory. On the memory, I manage to get it into 2080ti territory with an effective memory clock of 16.2 GHz by overlocking it by 1100 MHz. I did attempt to go high but we starting seeing artifacts in our runs.
With the memory overclock in place, I wanted to see if I could tune the core clock a little more than OC Scanner gave me. I was able to squeeze an extra 30 MHz with the peak overclock now sitting at 2025 MHz.
Running Timespy a final time we see a dramatic increase of 428 points in our final score. This has given us approximately a 5% increase in GPU performance.
Using Kill-A-Watt to measure the power usage on the system at the wall, it showed our idle power draw of 60W. During running, our final overclocked run of Timespy there I saw a peak power draw of 290W giving us a difference of 230W. Taking a look at our GPU-Z logs we saw the RTX 2060 Gaming Z topped out with a TDP of 106.7% pulling at a total of 202.7W.
During our synthetic and gaming benchmarks, the RTX 2060 Gaming Z was whisper quiet with the fans only kicking in at 60C. Once the fans did kick in, the TWIN FROZR has no issue maintaining a max temperature of 65c. Personally, I like to keep my graphics cards below 60c while gaming and this is no problem with the Gaming Z. During all-out OC testing, we did run the fans at 100% (which were quite loud) and the RTX 2060 Gaming Z on hitting a max temperature of 52c.
