[SOLVED] Two Questions on the ASUS ROG Strix X570-E Motherboard

[Beguzzles]

1st) Has anyone upgraded from a Ryzen 2000 series CPU on this motherboard to a Ryzen 3000 or 5000 series CPU? If I use a Ryzen 7 2700x CPU to check the motherboard, and install Windows 10, and when my Ryzen 9 5900x cpu arrives in a couple weeks, will Windows upgrade the PCIE bus to 4.0 from 3.0, plus make any other necessary changes? Or if I install Windows 10 with a Ryzen 7 2700x cpu then will I have to reinstall Windows 10 when upgrading to a Ryzen 9 5900x cpu on this motherboard?

2nd) As of August 2021 or September 2021, what BIOS version ships on this motherboard?

You can switch from a 2000 to a 5000 on that board without reinstalling Windows. Everything should be fine.

You will need the good BIOS update for that 5000 to work which is version 2606 minimum for the 5000 to be supported.

When you get your 5000 just update the BIOS to the latest version with your 2000 installed and switch to the 5000.

No way to tell which BIOS version comes with the board unless you can see the sticker on the box saying which BIOS it has. It's not the first BIOS available for that board anymore. It's probably something earlier but not the most latest BIOS that's for sure.

Thanks, I thought Windows 10 would recognize the changes in PCIE bus (3.0 to 4.0) automatically, but wasn't sure.

I got the motherboard today, but I surprisingly do not see any BIOS version sticker on the box or even a date of manufacturer sticker. I usually use Gigabyte, but trying Asus this time, and surprise there isn't a sticker on the box with this information.

Well just install the 2000 and look at the BIOS version in the BIOS. It's just important to update the BIOS before switching to the 5000. A 2000 will work out of the box like a 3000.

The PCIe bus is already PCIe 4 capable...it only needs the devices that attach to it to be PCIe 4 compatible. That would mean CPU, NVME drive, GPU mainly.

You shouldn't need to re-install Windows with just a CPU upgrade but it's always good to have backups in case anything does happen to make it necessary.

One thing you must do though is reset CMOS after changing CPU's.
