Gtx 1080ti not experiencing overclocking issues
i am using an i7 8700 with msi gtx 1080ti, 16gb ram, an asus z370 f gaming board, a 1080p 144hz monitor.
i have been running the 1080ti at stock speeds for the past two years, achieving clock speeds of 1899 and 5503 mhz.
yesterday i decided to overclock it and found the ceiling at 80mhz on core and 350mhz on memory.
beyond that the card ran smoothly during furmark 4k tests but not during games.
so i kept the previous settings and played f1 2020.
after overclocking, i achieved an average of 180fps, but after each lap the fps gradually decreased by about 10 laps.
after roughly 15 minutes of gameplay my fps dropped to around 99 average, then continued falling.
i checked the msi afterburner graphs: temperatures averaged 73 and peaked at 77, while power dropped from 88% to 65% in that time.
i reversed back to stock settings and played again. now everything runs smoothly with steady performance between 75-80%.
how should i overclock my card for the best results?
please help.
The thermal readings for the stock were observed. Even with your OC configurations, the GPU core continues to modify its frequencies according to power and thermal capacity. This explains why core clock OCs aren't optimal on 10, 16, and 20 series cards. Memory adjustments don't occur automatically. It might just be that the GPU is reaching one of those two temperature limits sooner and slowing down more often due to this. Since your power usage isn't at its maximum, the GPU likely isn't handling the temperatures well enough to maintain those speeds. These cards have several temperature thresholds. 2) The Furmark 4K benchmark doesn't fully reflect all games or their specific GPU usage patterns.

on stock settings I ended up with higher temperatures because I used the stock fan profile for overclocking, while I created a custom profile after 70% where the fans were at 100%. The only change between stock and OC was the power drop during gameplay. Am I doing the overclock incorrectly, or is my GPU not strong enough to handle it? Even when the power dropped, the core stayed at 2000MHz, which was unusual.
Power and heat limits – whichever is reached first.
You should have applied the identical fan setting to both stock and overclocked configurations.
sure, i'll give it another go with the same fan profile and see what happens.
So I ran the test again using the same fan profile, but on a different track. On Stock I achieved an average of 156 FPS, while on OC it was 158. I set the core to 70MHz and memory to 250MHz. Both clocks remained stable throughout the test. For Stock, the core clock was 1899 and OC was 1974, but the FPS improvement was only about 1%. On Stock, the card ran at 85% power, and during OC it dropped to 79%, yet it stayed consistent without dropping. Is this kind of behavior typical, or should I leave my card in stock and let OC handle it?
