[mgcrafter21]

CPU: Amd R5 5600g

CPU cooler: segotep frozen 240

Motherboard: msi b450m a pro max ii

Ram: 32gb (16x2 teamgroup tforce)

M.2 : teamgroup mp33

SSD/HDD:Ramsta 256gb

GPU:Aisurix Rx5500xt HTM

PSU: Inplay Gs650

Chassis: inplay meteor 01

OS: window 11 24h2 26100.2448


Monitor : Nvision N2455 pro and N200hdv8

I'm using both M.2 Nvme and Sata ssd at the same time
also done the ff things that i found on internet
- reseated gpu and cpu and other components
- updates all drivers and software including bios, chipset and Os


Before i was using rx580 and it also runs halves of pcie (x8 instead of x16) because I'm using nvme but then when i changed it to rx5500xt but when i checked it runs at x4 . if I'm correct should it run at x8?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Did you run DDU to remove all GPU drivers(intel, Nvidia and AMD) in Safe Mode, to manually install the latest GPU driver sourced from AMD's support site in an elevated command?

Yes I've already done that

5600g's igp takes some of your PCI-E lanes from your primary slot. That is why you only saw x8 with the previous card. It might be showing x4, because that's a gen 4 graphics card, and you are stuck at gen3 due to CPU and motherboard.

Even though i disabled it?

Yea the 5600g only has x8 lanes available to the x16 graphics slot regardless if you disable IGP or not. Updated earlier post, your board limits you to gen3 as well.
