I recently upgraded my GPU and the Radeon software shows that it recognizes the PCIE 4.0 card but is running it at PCIE 3.0 bandwidth? I can not figure out why this is happening, or am I reading the Radeon system properties incorrectly? 

 

ASUS TUF x570 + wifi

Ryzen 7 3700x

Saphire 5700xt GPU 

 

Properties from Radeon Software:

GPU - AMD Radeon RX 5700 XT - Primary/Discrete
VRAM - 8176 MB - GDDR6 1750 MHz
Graphics Chipset - AMD Radeon RX 5700 XT
Bus Type - PCI Express 4.0
Current Bus Settings - PCI Express 3.0 x16  (Shouldn't this be 4.0?)
BIOS Version - 017.001.000.068
BIOS Part Number - 113-1E4260U-O4E
BIOS Date - 2020/04/07 01:59
Usable Memory Size - 8176 MB
Memory Type - GDDR6
Memory Clock - 1750 MHz
Core Clock - 1815 MHz
Total Memory Bandwidth - 448 GByte/s  (the online converter said this was 56GB/s, isn't pci 4.0 supposed to be 64GB/s?)
Memory Bit Rate - 14.00 Gbps
OpenGL® API Version - 4.6
OpenCL™ API Version - 2.0

Software Version  2020.0909.2058.37766

 

I tried to reinstall the software/ drivers, i even did a factory reset install of the radeon software, this did not change anything.  

 

I'm not sure what to do now?
