Why is my GPU core clock so high?

[krytexgaminghd]

My games kept crashing and I kept getting a coloured then black screen after installing my new 980ti.
I found this guy's video who told me to reduce the core clock, memory clock and power limit to minimum so I did and tried fortnite on high settings. It worked fine with good temps when I checked MSI afterburner.
However, the core clock seemed exceptionally high with a fluctuation between mins: 1190 and max: 1391 which looked quite high (bare in mind this is with core clock at -90 on afterburner.
The game ran fine but I'm afraid this is high and may result in something bad or my game crashing during a fight. I am also wanting to play GTA 5 which is more demanding.
I would like to know if this is high and concerning, and if so is there a solution. Also my memory clock is a constant 3305. I would like to know if any of these are high or concerning as if not I will try to increase it slowly till it works without crashing (basically overclocking).

These clocks are normal. Since it works without artifacts, you shouldn't worry about it. When you are getting artifacts or crashes then the chip needs more voltage.

What if the voltage limit on MSI afterburner is constantly on 1 is that ok and what does that mean?

 

[Tolis_GR]

MSI allows a maximum of +100 mV if i recall this right. Increasing your voltage by +100mV is safe as long as your temps are normal. Where do you exactly see 1 as a value for voltage limit? On the main interface?

 

[krytexgaminghd]

On the hardware montior tab to the right of the main interface where it says voltage limit it is either 0 or 1 and when gaming it constantly 1 but when idle it is 0 idk if this is bad or not

This simply means that the gpu is hitting the max power draw so you 're on the max voltage as well. 1 means positive, which is actually like voltage limit= true. Nothing to worry about.
Overclocking the gpu is a combination of increasing the core/memory clocks, along with voltage and power/temp limits. You have to slowly get to the sweet spot. Better have some research on overclocking gpus before starting.
