You can also run the Port Royal or Timespy Extreme stress test in 3DMark. I first run Bright Memory: Infinite Ray tracing for at least 30 minutes while logging the data via GPU-Z. It might be even better or need a bit higher voltage. Also remember that just because we could undervolt our cards to a certain setting does not mean your card will work the same. There shouldn’t be any risk for damage to your card but just be aware of any risk regardless how minor it is. Remember that you take full responsibility when messing with your card. I undervolted both the Gigabyte RTX 3080 Eagle OC and the Gigabyte RTX 3090 Eagle OC but in the images below it is the RTX 3080 that is used. Bright Memory: Infinite Ray Tracing Benchmark from Steam: this was also used to test the stability of my settings.3DMark: I used the stresstest feature to test my settings.
MSI Afterburner – latest beta: This software allows you to set the clock speed at specific voltages.GPU-Z : This was used to monitor the card for both temperatures and voltage.The software I used for this article was: In the following pages you can both read on how to do it yourself but also get an idea how it will affect both the performance but also the thermals (and noise level). Since the RTX 3080 and RTX 3090 came out there has been a lot of talk about undervolting them to get better thermals while still getting kick-ass performance and of course I decided I wanted to try it out myself. This isn’t anything new either and has been done both to GPU’s and CPU’s to helt them with thermals although I think it still isn’t as knows as overclocking. What if you instead could find a way to lower both the temperature and the power draw while still getting almost the same performance? Well, there is. Running a card at a higher clock speed might mean a bit more performance but it also usually means higher temperature that needs to be removed = fans work harder = higher noise level and it also usually means the card needs more power. So while the Gigabyte RTX 3080 Eagle OC have a 1755 MHz Boost clock it actually often boosts even higher (I’ve seen up to 1900 MHz). For a few generations of GPU’s now the GPU’s have no longer been running with a set clockspeed instead boosting to a higher clockspeed that is partly determined by power target limit and temperatures. Usually you just increase the clockspeed, sometimes with an extra increase in voltage and presto! Increased performance. This is something that has been done to both CPU’s and GPU’s for many years. I think most of us are pretty familiar with the concept of overclocking.
