I’ve got the 7600 running on a Gigabyte B650I motherboard. There are 3 total PCI M.2 slots, and 1 PCIe x16 slot for GPU. During my build I put together all components except the GPU, fired up Windows on M.2 ssd and loaded drivers with no issues. Then when I plugged in the GPU (RX6700) and tried to boot, my M.2 ssd could not be found in the BIOS.
Eventually I was able to boot up with both the GPU and ssd working but not until I set the motherboard to split the PCI slots @ 8x for GPU & 4x each for PCI M.2 slots A & B (both on CPU bus, my ssd is in slot B). PCI M.2 slot C is on the chipset bus and I would move my ssd there but it’s on the back of the motherboard covered by a metal plate and I really don’t want to take apart my ITX case again to get to it.
The Gigabyte B650I will supposedly bifurcate the PCI slots automatically but my experience only worked with manual settings. The problem is if I put the pc to sleep, when I go to wake then my M.2 with Windows installed cannot be found and I have to hold down power to shut down. Then another power cycle will get me back into Windows again.
I’m wondering if anyone is aware of any limitations on the Ryzen 7600 that would prevent the Gigabyte PCI bifurcation from working in auto mode as expected. Or if there are any known issues for wake from sleep?
