Cannot boot with GPU


Recommended Posts

GPU: (AMD Radeon RX580)

Since Ryzen 3700x has no integrated graphics, I had a GPU plugged in the first time I booted unraid. It started but just kept saying "amd-vi: completion-wait loop timed out." Eventually, I just shut it off, removed the GPU and it booted up fine. IOMMU is enabled in the BIOS and SVI is also enabled. I rebooted again, this time, I checked the BIOS to make sure the m.2 ssd is detected; it is but it's not showing in unraid.

UPDATE:

System boots and detected the GPU only if IOMMU is disabled.

SSDs in the array are not recommended. They cannot be trimmed, some implementations might invalidate parity, and in any case they can't be written faster than parity anyway so I don't know why you would want to do this.

 

SSDs in the cache pool or as Unassigned Devices is what everyone else does.

Thanks, I'll use it as cache then.

For my ignorance, I'm contemplating upgrading to a Ryzen 5 3600 setup.  Do I NEED a graphics card to run unRAID?  I'm coming from an old crusty i3-6100 with integrated graphics.  I do not use any VMs yet, so I'm not worried about having to pass it thru.  I just want to make sure that the mobo will POST without a graphics card and that unRAID will work.

 

Thank you in advance.

You don't need a GPU.  Whether or not the motherboard will boot however without a GPU is something dependent upon it itself.  At the very least, you WILL require a GPU to at least setup the boot order in BIOS.
