Why does my gpu drop Mhz while playing?

FastGamingYT · Jun 15, 2018

I have a gtx 980ti and sometimes it just dropps the mhz to a low number and than it comes back but when it dropps its really noticeable and frustrating.

Nvidia GPUs do a self overclock called a boost speed and only do it until they get hot or draw too much current. You'll usually see your top boost speed for a minute or two and then normally a speed slightly higher than base afterwards with fluctuations.

For example, my laptops 1050 has a strict power budget that can't be altered. It starts benchmarks at 1833MHz for about 5 seconds then drops down to 1200MHz for the rest of the time. This is even after applying liquid metal and manually overclocking the GPU. It's cool and set to run much faster, but I don't have an override to the current/power draw.

Your Ti, is most likely hitting a temp or current limit. You can check with EVGAs XOC software, or GPUz.

Did you even check that you are not hitting any temp limit?

Provide very little intel and your reply towards MCmunroe was "blunt".

Im not hitting any temp limit. Its 75c at max. No overclock. Do you need any specs? Help.

full system spec, include make and model of the psu

What the cpu/gpu temp and usage during the games?

only happening when you streaming?

No.

I5-4460; (zotac)gtx 980ti(omega edition) 2 HDD-s; 12gb or ram ddr 3 1600mhz; Psu: Corsair vs650; MB: Asus h81m-k

In rust is happening the most and there are the usages: GPU: 50% or lower CPU: ~60% Memory: ~80% Disk: 50-80%
