Hardware for my new test proxmox server

[Anila]

Hello guys,

i want to build my first own promox vm server with the following hardware:
Mainboard: ASRock X570 PG Velocita
CPU: AMD Ryzen 7 5700G
GPU: 2x Nivida Tesla K80 (with SLI-Support)


Do you know some issues ?

I dont find any problems on "hardware search"

X570 chipset is the best choice for PCIe passthrough on Ryzen. I went with Gigabyte AERO because it has no fan, two separate USB controllers that can be passed through and the choice of boot GPU in BIOS.
5700G is great for Proxmox host console (but don't try to do passthrough). It will make the first PCIe x16 slot work as x8. This is not a big deal on the Velocita but would disable one x16 slot on other motherboards (like the Gigabyte AERO).
Note that your K80 GPUs, when put in the PCIe x16 slots, will run at x8 and x4. This is probably not be a problem (depending on your use case) and you'll probably need Threadripper, EPYC or Xeon if it is a problem. Best you can get on other consumer motherboards and without integrated graphics or APU is x8 and x8.

Could you give some insight why the first PCIex16 goes down to x8?

Because the iGPU is needing those PCIe lanes. If you want those lanes for you PCIe slots you have to buy a CPU without an iGPU.
