My gtx 1080ti is not getting hotter when I turn up the speed.
i have an i7 8700 msi gtx 1080ti with 16gb of ram running on asus z370 f gaming board, and a 1080p 144hz monitor. for the past two years, i ran my 1080ti at stock settings, which gave me clock speeds of 1899mhz for core and 5503mhz for memory. yesterday, i decided to try overclocking it, but after a few laps, my card hit a limit on the core (80mhz) and memory (350mhz). even though furmark 4k test ran perfectly without issues at those speeds, games didn't work well. so i stuck with 80/350 for now.
today, while playing F1 2020 after overclocking, my average frame rate started going down slowly as the laps increased. by about 15 minutes, it dropped from an average of 180fps to just under 100fps. Then i checked the msi afterburner graphs and saw that while the temps stayed around 73-77 degrees, my power percentage was dropping wildly from 88% down to 65%.
i took it back to stock settings and restarted the game. on stock mode, everything ran smoothly with no drops in power, staying steady at 75-80%. I don't know how to properly overclock this card for the best results. please help me understand what is happening here.
1) What was the heat like on the stock stuff? Even with your new settings, that specific card will still try to change its speed based on how much power it uses and how much room there is for more heat. This is why the overclocks (or "OC") don't work well on newer cards like the 10, 16, or 20 series because they hit limits too fast and slow down their performance just to stay cool. Memory doesn't change automatically either, but it's a guess that could be just one of those two temperature problems. Maybe the card is now running into trouble faster than before, so it shuts things off more often to protect itself. Seeing that your power setting isn't at 100%, the card probably isn't happy with how hot it runs and can't keep up with those speeds. These cards have many different temperature limits.
2) The Furmark test for 4K doesn't show every game and how they are built to use the graphics card. It's better to look at actual games themselves because that is the best way to tell if your card really works right.
What happened with your heat levels on stock? Even if you set up your graphics card's core settings manually, it still changes its speed and power based on how much room there is for heat and how much electricity can be used. That's why overclocking cores doesn't work well on 10, 16, and 20 series cards. Memory isn't automatically adjusted either. I'm not sure, but maybe the card just hits a hard limit faster now and slows down more often because of that. Since your power usage isn't always maxed out, the graphics card probably doesn't feel comfortable with those temperatures to keep going at full speed. These cards have several temperature limits. 2)The Furmark 4K test doesn't show how games actually use the graphics card since each game has its own program. The best way is to run real games. Some will let you turn things up high, but others might not even like it at all...
in the game settings, I actually hit higher temperatures because I used the stock fan profile instead of an overclock. I made a custom profile where after 70 degrees, the fans would go to 100%, but the only real difference between normal play and overclocking was the power drop during the action. Am I messing up my overclock or is this just something random that happens? Even when the power dropped down, the core stayed at 2000 mhz, which felt weird.
The point where power or heat gets you killed is up to luck, not just your setup. If you're running stock cooling but overclocking, you probably messed up by mixing two different fan profiles. You need to use the exact same one for both regular and overclocked modes so they don't fight each other.
Alright, I'll give it another shot with the same fan settings and see what happens now.
ok so i ran the test again using the same fan profile and used the standard benchmark on a different track with stock settings. on stock, i got an avg fps of 156 but on oc it was 158. after applying 70mhz to core and 250 mhz to memory, both clocks held steady throughout the test on stock while on oc they went up to 1899 for the core and reached a peak of 1974 on the clock speeds. yet the fps gain was only about 1 percent, which seems low since i expected much more. interestingly, on stock the card used 85% power during the test but dropped down to 79% on oc while staying steady without dropping like it did before. is this behavior normal? should i actually turn off OC and let my card run at stock settings instead?
