Zotac GeForce RTX 3090 Trinity – Lighter And Brighter Than Founders

Conclusion - Zotac GeForce RTX 3090 Trinity Undervolt

When you can't overclock, seriously this card will not overclock as it's already at its 100% power limit we took time to undervolt it to see if we could save some juice. If you want to see the entire process and how to do it for yourself, feel free to follow over the article where I first explored it with the RTX 3080 Founders Edition.

After a bit of tuning, we found two levels of undervolt. We were able to go for a middle of the road undervolt with a core voltage of 850mV and a target clock speed of 1850MHz. While the low range undervolt came in at 806mV and 1800MHz target clock speed. The power savings were quite immense and we found the performance from the middle 1850MHz load to the 1800MHz load resulted in a margin of error performance difference. We were able to see a total graphics card load reduction in our run from 369w down to 280w and the temperature dropped from 77C to 71.7C

You can see in the power over time chart that there were no wild spikes in the undervolted version and in fact, it stayed very consistent. through the run as opposed to the stock run.

We also wanted to take measurements of the clock speeds and as you can see across all settings the undervolt stayed consistent from start to finish, whereas the stock run started off higher and eventually fell to the level of the middle of the road undervolt. This would indicate to me that under extended gaming sessions the middle of the road undervolt might actually net you better long-term performance.
