Psu ,gpu or software? TDP drop anomaly.Question
« on: 16-September-19, 06:46:49 »

Hello. My card on stock,no oc. Msi Lightning Rtx 2080 Ti . Today i run firestrike and looking on msi afterburner. For a moment ( exactly 1 second ) gpu power drop for 1 second and clock ,look.

Here,gpu power 58% and clock 1575mhz,but gpu load 96% ( why 96% ? ):





And bum normal again:

Normal clock, 1980mhz:





Any ideas? Rest pc no oc. Psu is Corsair 850 RmX,9900K on stock. Why that happened?
GPU connected from 2 separate cables.



I mean why gpu clock dropped,gpu power dropped,but gpu load not dropped?
Ah i checked GPUZ during that moment and gpuz not reported that drop. Only Msi Afterburner. IS this possible that was MSI bug?


Pc is on stock,no oc. All is stable,no crashing,nothing like that i see in games. Today for split second in firestrike. I cant reproduce this even when running heavy tasks in background , no matter what clock not dropping again. ( during that test of course ).

So question. Sell psu or gpu and be free , or just what now?

It can be a situation when a new scene is loaded so gpu is less utilized.. Do you have any issue besides this graph?

So its not psu or gpu issue? I ask because like you see on diagram.



Red arrows. First time gpu power drop to 20%,GPU LOAD stays 96% ,but clock steady 1980mhz
Red arrows 2: Gpu power drop to 58%,GPU LOAD still stays 96%, but this time clock dropped to 1575 mhz for a second.

And why then GPU LOAD not dropped?

Anyway i cant reproduce this again.
Anyway i cant reproduce this again with the same apps in background. Now its smooth without that stutter,weird

But its was not hardware related?

Again, do you have any problem besides this graph? It looks all perfectly normal. So far no hardware issue is apparent.

That is irrelevant. What issues did you have besides the graph?
