Question RX 6600 XT Low power draw, voltage and frequency

[swazive]

I recently upgraded from a GTX 950 to an RX 6600 XT and when playing games the fps was much lower than expected. (examples - 80 - 120 fps on apex legends 1080 max, 180 fps on rainbow six benchmark at 1080 high) When monitoring the gpu it showed that the voltage rarely passed 750Mv when playing games and power draw was around 50w. The gpu clock was also very low, some games it ran at 800-1.2k MHz and some others 2GHz. Running benchmarks like 3DMark Timespy and Furmark shows that the card is running normally in those, as it works how I would expect, using the full TDP of the card and boosting to 2.6GHz. I have opened a support ticket with Sapphire and they have told me to play my games on 4k as 1080p isnt demanding enough, which isn't alot of help. What else can I try to fix this?

Things I have tried so far:
Fresh install of drivers (multiple times)
Updating bios
Changing power plan
Increasing power limit in Radeon Settings
Turning on/off freesync
Changing graphics profile

System specs
Ryzen 5 2600 @4.1GHz
Sapphire Nitro+ RX 6600 XT
MSI B450M Gaming Plus
1x16GB Corsair Vengeance LPX 3000MHz
Corsair CX650M PSU
I should also mention temps are very low, CPU averages about 55 degrees in gaming, and the GPU sits around 65 under load.

You should just be able to reinstall windows, a fresh install fixed it for me.

nope it didnt work for me.. anyone else having the same issues? unstable fps and game stuttering.. r5 3600 and rx6600xt

I have the same issue
ryzen 5600x
B550m aorus pro
Rx 6600 xt red devil
Ram Tridentz rgb 2x8gb 3200mhz

same issue, what on earth is going on. my apex only draw 32 watts with 1460mhz clock, then low fps and stuttering.

i suspect it happens after i swap my RTX 2060 super with RX 6600 xt, although i uninstalled it with DDU multiple times.

I have the same issue, did you find a solution?

Yes, i fixed the issue. But its uncommon. Currently I'm using Tridentz RGB 2x8gb 3200Mhz.
On CPU-Z it reads there are 16gb of RAM, but on the system (task manager) only 8gb. That means it runs only with single channel RAM. Plus I didn't notice the RAM frequency and timings just going wild. The RAM RGB light is on as usual tho, even I can change the light color with Gigabyte Software but still only read 8gb. Just fixed it with cleaning the RAM.

So, don't trust CPU-Z haha.
