[SOLVED] Gpu at 100 load but mhz not stable

[Optical Use Gamer]

hi i have an rx 580 4gb from gigabyte, not oc, its stock, 1340mhz core clock, with an i3 10th gen, and lately afterburner shows in evry game i play that my mhz is 1280 or 1300, 1320, 1285 mhz, its almost never capped to 1340, even in heaven benchmark extreme settings the gpu maxed out on 1328 mhz, how can i fix it

Your clock speed will vary depending on workload, utilization, and temperature. This is normal.

but isnt it supposed to use full clock speed at 100% usage? for example in games like warzone, gta v? and the tempreture never went above 75 degrees c

No it's not supposed to use full clock speed at 100% usage. That's why when you have gpu issues with a game you have to see the core clock that is being achieved and then the usage. You can have 100% (or close to that) usage with the low power state clocks (which are normally 20-35% of max clock).

so what are you saying is that everything is ok, and this is normal?

 

[dotas1]

Yes it's normal. No gpu is constantly at max clocks. Thermals, power and workload needed are the three variants that fight each other to achieve a certain clock, including max.

ok thx a lot, one last thing, is it safe to undervolt it, i saw that it may give you better temps and a slight performance boost?

 

[dotas1]

Indeed it does. I have undervolted mine and the results are -11C from previous max with the exact same clocks. I can go to -6C with even better clocks than the previous but I prefer to have the card run cooler.
If you undervolt it through software and not vBIOS, it's pretty safe. Although you need extensive testing so you can find the sweet spot. Determine the desired max clock and then keep lowering the voltage till it crash in benchmarks. Then up it again 30mV or more and run benchmarks again for stability. If it can run without crashes after 2-3 hours you are gold!

thx a lot, ill just use amd software, its the easiest, ur a life saver
