2080 Ti Aorus Waterforce - clock spikes in 3dmark sometimes

[nnn123]

Hello.
I have a question. I am using Rtx 2080 Ti Waterforce and 9900K and Corsair 850RmX. ALL stock,no oc.
Drivers up to date,Windows 10 1903v.

Few days ago ,when i run Fire Strike GPU test 1 on loop, i saw a clock dip from 1980mhz to 1570mhz for 1ms. GPU LOAD not changed,it was 96%. Only gpu clock dip for a 1ms.
I checked in logs,and during that gpu power drop to 58%.

I cant reproduce this.

Second.
Yesterday i run TimeSpy looped gpu test 1. Clock during 40 minutes was 1920-1970mhz with random power usage. But one time it dropped to 1800mhz. Is this normal? Screens:

1920mhz:

And that 1800mhz for 1ms:

Of course its POWER LIMIT only in this test. So i guess its not faulty somewhere? In games i dont had any once such drops in clock.

If these drops aren't affecting real-world usage or applications, then don't sweat it.

Yeah i know but why it happening in 3dmark??

If this happens once per your 40 minute test and is not present in games, why spend time investigating? Could be scene change, power drop etc. there are thousands of other factors that could cause a power to the card fluctuate.

TimeSpy equals never the same result. I do a reboot between runs.

It is also sensitive to other apps and background programs.

Test with Heaven or Valley looping to see if you can duplicate it.

 

Your GPU is running really well for stock so with the power target at max you should be in between 2040 and 2070mhz.

I have only been able to maintain 2100mhz keeping below 64c and in some games 2100mhz equals an instant crash for some unknown reason.  

 

 

Also overclock the i9 9900k to 5ghz on all cores. 2080 tis like it.

Hello.

I left Assassin Creed Oddysey for overnight ,check in morning gpu clocks and on 6:34 morning just for 1 second,clock dipp from 1995mhz to 1245mhz and power to 38% TDP. For 1ms

PC:
9900K stock temps ok
Corsair 850RMX
Asus Prime Z390-A
Aorus Waterforce 2080 Ti Xtreme temps ok

Windows 10 V1903

Is this ok?

I mean rather its "game" not hardware issue?

Clock speeds will fluctuate based on what it needs, its not always going to stay pegged out at max boost. If you didnt notice any stutter or game play issues, then thats likely what happened.

i left for overnight running game. Character was standing on the same place. On morning i checked logs,and on that second it dips to 1245mhz for 1s.( 6:34:43 ) Nothing to worry about? It was propably stutter?

[Skiiwee29]

nothing to worry about.. and why would you do that? It was probably an anomaly.

ok thx, i forgot to exit game, i was sleepy

 

Hey last question. Somebody said:"There's chance that a voltage instability from the PSU caused that. For example, I have a very unstable power outlet, drops to 180ish VACs from 230VAC for a few milliseconds. These kinda stuff happens to me almost every hour."

Is this possible?

 

Hello. I have an question. Its my second similiar topic here,but i want to be sure. All of you have knownledge here.

I left Assassin Creed Oddysey for overnight ,check in morning gpu clocks and on 6:34 morning just for 1 second,clock dipp from 1995mhz to 1245mhz and power to 38% TDP. For 1ms. Gpu load stayed 98%.

When i go sleep character was just standing on the same place in game.

Somebody said:" it's voltage instability from the input power source (230 VAC 50Hz). You need an Uninterruptible Power Supply."

Is this possible?

PS: I am on the newest nvidia drivers
