Budget VFIO build in NOV 2023 - How I found the perfect motherboard (for me)

Hello everyone!

Mainboard Requirements:

  • BIOS option to choose which PCIE slot is used at boot (Only on Gigabyte X570 boards?)
  • BIOS option to enable native ACS for for further group segregation
  • 2x PCIE 4.0 Slots ( 1x X16, 1x X4) (1 primary guest GPU / 1 secondary host GPU)
  • 6x SATA 6Gbit/s (4x also acceptable)
  • Onboard Audio with Center/Sub, Rear and Line Out connectivity (for 5.1 analog)
  • 2x M.2
  • Decent VRMS with at least 7 real phases and ~60 Amps Mosfets
  • Mem OC rating of >4800
  • $250 - $300

Virtualization:

  • Guest / Windows Gaming VM: 1x NVME, 1x GTX TITAN (PCIE slot 1 @ x16), 1x Soundblaster FX Soundcard (PCIE slot 3 @ x2) 1x USB Controller, 2x SATA HDD

  • Host / Arch: 1xNVME, 1x GTX 1060 (PCIE slot 2 @ x4), 2 Cores, 1x USB, 2x SATA, Onboard Audio

Conclusion:

I’ve been planning a 700$ budget VFIO build for a while, reading every single thread and recommendation about various boards and their IOMMU groups.

It seems that AM5 with B650 and X670 chipsets, at a mid-range level, don’t offer any options with decent IOMMU groups, and those who do are lacking in other areas. Most of them have a group with all of the chipset connectivity lumped together. I understand that this is due to Asmedia being the chipset supplier.

So after days of searching and comparing data, I’ve decided to use the GIGABYTE X570S AORUS Elite AX with AM4 socket and X570S chipset for this build.

It fulfills all my requirements, has reportedly got perfectly separate IOMMU groupings and costs < $300

One potential issue might be groups 12 - 14 on the X570 AORUS Elite (non AX)

Group 12:
	03:08.0 PCI bridge [0604]: Matisse PCIe GPP Bridge [57a4]
	05:00.0 Non-Essential Instrumentation [1300]: Starship/Matisse Reserved SPP [1485]
	05:00.1 USB controller [0c03]: Matisse USB 3.0 Host Controller [149c]
	05:00.3 USB controller [0c03]: Matisse USB 3.0 Host Controller [149c]
Group 13:
	03:09.0 PCI bridge [0604]: Matisse PCIe GPP Bridge [57a4]
	06:00.0 SATA controller [0106]: FCH SATA Controller [AHCI mode] [7901]
Group 14:
	03:0a.0 PCI bridge [0604]: Matisse PCIe GPP Bridge [57a4]
	07:00.0 SATA controller [0106]: FCH SATA Controller [AHCI mode] [7901]

However, I read that by enabling ACS in the BIOS all of those should break up nicely, so I’m hoping that’ll work. There are much newer BIOS versions out atm, so I guess it’ll be a bit of a gamble.

I’d love some feedback and recommendations in case there might even be a better option out there.

Thank you, that’s some beautiful groups.

The Creator is like $280 I believe, not bad.

Would you happen to have any knowledge of the MSI B650 Tomahawk’s groups?

Asrock B650 live mixer should work out too. It groups the huge amount of USB ports, so you most likley won’t need a dedicated USB PCIe card and you can still put 3 pcie cards in there, if you need to.

Here is the link to the OP, detailing the groups:
