X370-i Gaming and upgrade to 3000 series CPU & Intel Arc B580 OC Edition

[fatman80]

Hello all

I am upgrading from an AMD Ryzen 7 1700 to a newer chip. It's a budget system, and I don't really want to have to update my MB if I can help it. I game lightly these days and the PC is mostly for my kids.

I have a X370-i Gaming and want to upgrade my GPU to an intel Arc B580 12GB, but it needs support from a 3000 series processor and need Smart access memory/ReBar support.

I read that the X370 MBs have had support for the 3k chips added and a simple BIOS update will enable these to be used.

It isn't clear if all 3k chips are supported?

If yes, I am looking at a AMD Ryzen 9 3900X, has anyone done a similar upgrade?

Also does the BIOS update give the option of BAR/SAM for my MB?

Cheers

So it looks like both are supported. I have my upgrades up and working.

For anyone else out there with a similar scenario, these are the hoops I needed to jump through to get everything working.

Update BIOS via USB to latest version

Replaced CPU

Updated windows to latest version

Used MBR2GPT within windows to update my boot drive to GPT (it was set to MBR & labelled Disk 3 in windows disk management)

Booted to BIOS to disable CSM to run in UEFI & enable windows to boot

Installed Intel drivers

Enabled Resize BAR in BIOS

Installed new GPU

Used DDU to remove all of the old Nvidia drivers
