Hello. I run looped 3dmark 11 and i saw that clocks are dropping below advertised boost clock Boost Clock, 1582 MHz. Dropping to 1506- 1540- 1560mhz under load with 84C. I am using auto fan and stock settings. Can i rma because of this? I was thinking that clock always should be above Boost Clock, 1582 MHz. Card is 1080 Ti Fe.
 
Shouldn't be dropping below the advertised boost clock - normally you will see 100-200Mhz over the rated boost clock with some variation.
 
Also i am getting that drop to 1500-1590mhz only in 3dmark . In games i have 1650-1800mhz, so airflow i think its ok. But still shouldnt dropping?
 
Grab GPU-Z and see what the perfcap reason is in the sensor tab when the card drops below advertised boost clock.
 
Yes probably a temperature issue. The single tiny fe fan is completely useless even on a lower power rated card yet alone the 250w of the 1080ti.
 
Erm,no,that'll be daft IMO.
Boost clocks are not guaranteed - it's a boost that is there under certain scenario's, otherwise the default clock would be set at the boost clock speed. As temp rises the boost reduces.
 
Increase fan speed, fit an AIO or get a better AIB card.

It's probably dropping in 3D mark due to the FE poor 6+8 pin power delivery and cooler.
 
Sounds like the card is adjusting clockspeeds inline with temps which they are supposed to do. You can increase the fan speed to lower temps or put up with lower clocks. What case do you have, how many fan's are installed in it and how are they set up (intake/exhaust)?
 
Hey. Appreciate for help me. I tested now GTA V and getting 1650-1770mhz clock during . Only looped 3dmark struggling my clock to low 1500mhz. Anyway its good that games are not throttling my card heh. And i dont have artifacts.

Base clock is the only guarantee. Anything above this, boost is behaving correctly.
 
If it was guaranteed, it wouldn't be called a boost clock. This is how both CPU and GPU manufacturers have increased clock speeds over the years - by claiming a high boost clock and a modest base clock, so that when chips throttle due to high thermal output and/or power consumption, they can go "only base clocks are guaranteed". Bit of a con but the alternative - having to manually overclock every chip to reach anywhere near its potential - is probably worse.

Games aren't as taxing as benchmarks, in general, which is why you're only seeing it throttle in the benchmark. Better cooling could resolve this if you really cared enough about benchmark scores.
