2080 Ti - 1ms clock drop during FireStrike

[sew333]

Hello.

I have a question. I am using Rtx 2080 Ti Waterforce and 9900K and Corsair 850RmX. ALL stock,no oc.

I run 3dmark firestrike 1920x1080. Monitor 1440P native.

Using Msi Afterburner not the newest,and riva tuner statistic.

 

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%.

 

Log from MSI:

 

 

But then i look at gpuz and gpuz not report that,all was fine,no drop in clock and power.

 

I tried to replicate that. So i run in windowed mode Fire Strike and was messing in Windows, to force gpu power drops. It drops gpu power but clock was steady and not dropped,like before.

 

So why i cant reproduce that clock drop anymore? And why that happened? Should i worry?

IIRC the new beta of MSI Afterburner features core clock lock. That should fix it

Hello thank you for reply. Also when t happened once, and i am not able to reproduce ,no worries?

[BitMaster]

lemme say, sh!t happens :smilewink:

 

If you dont already use MSI Afterburner then I suggest you give it a try, most of us gamers in general use it to graph & measure the system.

But this graph is from MSI AFTERBURNER but i think its not the newest version.

ehhh sure, lol, my mistake

[sew333]

So update Afterburner it will help if accidentaly i will be have the same drop in Firestrike? But i cant reproduce this anymore , so i doubt it will happen again,heh.

[sew333]

Like you see my Afterburner version is 4.6.0, so update to 4.6.2 , it can help?

if I have to answer this question for you I ask myself if you can adjust it accordingly to lock the clock at a certain MHz value.

 

Try it out, trial & error is the way to go. Just know what you are doing and do it 1 by 1, not many things together or you will get confused and lost.

Hey last question and we can close topic. That power drops and gpu core dip for 1ms was not caused by faulty Gpu?

[BitMaster]

no

[sew333]

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

 

 

 

Is this ok?

[BitMaster]

yes, dont worry

 

Your pc does many many things over that time period and sometimes your game is not top priority.

 

Let loose and feel safe, you are not running an ICBM site with 24/365 duty after all.

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?

[Demon_]

How do you know that the 230VAC drops to 180VAC? Where are you? What is your PSU? How old he is?

Maybe you need an UPS.

I am in Poland. PSU is 10 months old. Corsair 850RMX.

 

How do you know that the 230VAC drops to 180VAC?

I dont know but this guy said this to me,that maybe.

[Demon_]

The Corsair RMx are very good (Tier 1).

If the voltage drop from the wall, the PSU can do nothing.

So it was not voltage instability ?:)

[Demon_]

Yes, it's voltage instability from the input power source (230 VAC 50Hz). You need an Uninterruptible Power Supply.

Wait so clock dropped for 1second because is instability from input power source?

Cpu clock was 4700mhz steady. Only gpu core clock dropped to 1245mhz for 1 second.

 

I was thinking that pc will get off not like that.

Wait so clock dropped for 1second because is instability from input power source?

1 second is a lot for a 2080Ti who need 250w to run. From what you say (input 230VAC power drop), i suppose yes.

If the input source dropped far enough to cause your GPU to drop in clocks, which I honestly doubt that happened, your whole machine would do a Insta-Reboot.

 

Whatever you see has a different reason but it is never a bad idea to have an UPS.

 

If you care for your hardware, get a UPS with a Sinus Wave and not a rectangular shaped Volts output. Cheap ones are rectangular, better one have a true sinus wave shape output.

 

I would not care for that drop, honestly, but that is up to you. The UPS is a question of money or opportunity, but rather have none than a 90° brick.

[sew333]

I tested Metro Exodus,Shadow of T Raider,Control,Unigine benchmarks no drops like on AC.

But this is not a real problem ,because in AC its not have impact on performance,maybe -1 fps lost.

Also it happens very rarely like once to 5 hours it will drop for 1second.

That depend of the drop amplitude and duration. The video card is the component who needs a lot of power and is affected by voltage ripple. But yes, i agree with you.
