why can't i change gpu clock?

[Banditas]

I got a new gpu and I'm trying to overclock it, but when i try to change core clock, it shows on gpu-z that it got changed, but when I run benchmark test, it keeps jumping at like 1130-40 even tho I set it to 1300. How can i fix this or it should be like this? My gpu is radeon rx 460.

Some GPUs also come with O.C. software. Like MSI afterburner. Are you using the offical software to O.C. the graphics card?

I'm using both amd wattman and afterburner, but I'm using wattman for the first time, so maybe there is a setting or something that turns that jumping off and I don't know about it
