What steps can be taken to enhance the 3090 OC?
Hey everyone,
I've been adjusting my 3090 Strix manually. I set the power limit to 110% (should be 380W), adjusted the 1920MHz to 0.875mV, and didn't change the core clock slider. Added +250 on memory. No crashes in benchmarks, but the time spy extreme stress test didn't pass (96.5%). On timespy benchmarks: 20450 graphics score at 1440p, 10350 at extreme, and 13800 on port royal. Running at 2170 RPM with 69C and temps. Core frequencies appear to oscillate between 1830 and 1920.
Any tips to boost performance? Should I be concerned about the failing stress test result?
I want a consistent 24/7 OC and prefer not to raise temperatures or fan speeds beyond current settings. Thanks for any advice!
As a reminder, there may be times when your GPU performs well under stress testing software but becomes inconsistent when used with games. You might want to run a game on your system (if it’s intended for gaming rather than just benchmarking) to check if the card remains stable with your current overclocks. Power usage is often the main factor, unless thermal issues arise. What temperature range are you observing, and what kind of airflow are you experiencing?
I owned a Gigabyte 3080 Gaming OC and experimented with overclocking. The 3080 shares similar limitations with the 3090 regarding overclocking potential. While I could boost numbers in synthetic tests, the actual performance improvements in games were minimal and didn’t significantly affect gameplay. Some settings performed well in benchmarks but failed to hold up during specific games. After returning the card to its original state, I realized the benefits of overclocking didn’t justify the increased heat and power consumption for barely noticeable gains.
It would be nice if everyone shared my perspective. I do understand.
I’m confused about why someone would need to overclock an RTX 3090.
If a program or game runs poorly—even at around 60 FPS with this card, like MS flight simulator—then extra frames won’t matter much.
And for games that run at 200–300 FPS, any difference is negligible.
So the question really is: What’s the point of overclocking?
Exactly correct, I didn't encounter any problems during benchmarks and stress tests, though the card failed at 4k for an hour in Cyberpunk 2077. Reducing the core clocks to 30 MHz seems to be working now. Observing that after setting the frequency/voltage curve down to 0.875 mV, the card appears to be operating within its power limits. Likely the next move is to complete the voltage curve. At 25°C ambient, I was seeing 69°C on the core and 84°C on the VRAM. The setup includes a Lian Li Lancool 2 Mesh, a 280mm AIO front, 140mm fans at the top, 120mm fans in the back, plus two 120mm fans below the GPU as intake. I've adjusted the GPU fan curve aggressively, which helped lower temperatures to around 67°C. The PSU is a Corsair HX1000.
Hey there, since your card already comes with a factory OC, you should have a solid experience with it. My 3090 didn't have any OCs by default, so it wasn't performing as well as I thought, which made me want to give it an overclocking try. You're spot on about the temperatures—just a little undervolting could help lower them.
