AMD RX 6600 on PCIe 3.0 Clock speed stuck on 1000mHz on 74% Utilization

I recently bought an AMD RX 6600 to upgrade from my GTX 1650

It felt weird seeing the fact that the clockspeed is like 24mHz on idle and 1000-ish mHz on 74% Utilization

Idle temps are on 37-38 degrees and 45 degrees on 74% utilization (are these normal?)

and is it normal for it to have only 29w power consumption?

 

p.s. ik the system is probably bottlenecked

and im running overwatch 2

What FPS are you getting in your games?

since i'm using amd freesync

so far all games i'm running are on a constant 60 or 75 fps

though my motherboard only supports pcie 3.0 (though i'm not sure if that's the real issue)

If your monitor is max 60/75Hz you won't get any more frames with Freesync enabled so your GPU don't need to be pushed more

Disable sync and check what happens

PCIe 3.0 probably isn't the issue - 3.0 slots have plenty of bandwidth for a gpu, especially a mid-range one like the 6600.

i get around 100-110 fps on cs:go
about the same for overwatch (all of them on ultra)

i also got the black screen on boot when i installed the drivers yesterday, which a quick hdmi replug apparently did the trick

When performance is limited by vsync, freesync, or gsync, it reduces the load on the GPU. This then causes the GPU to reduce clocks since there's less load on it, to keep your temps down, fans spinning slower, and reduce load on your PSU.

 

My 6800XT does this, in some games, I only see 600 or 800 mhz on the Core and the Memory clocks down as well; my fans spin at their idle speed (50%), and my temps stay really low, even though the GPU is kicking 144 FPS into my display. :3

 

TLDR: This is expected behavior.

ah ok understandable

but what about 30mHz on idle though?

The card severely reduces Clocks to save power when there's little load. My 6600XT right now is at 5MHz just browsing. The power consumption on the 6600s is quite low, it's showing around 80W in AMDs stress test for me. Also, temps will be very low due to the low power consumption, so I'd say what you are seeing is expected

 

As the others suggested, check the games without VSync/Freesync to see if it clocks higher then. Good Luck
