  1. Anybody planning a Ryzen build?

    Can someone running UNRAID 6.4 RC10 and Threadripper please try disabling ASPM in their BIOS (ASROCK boards have this, not sure about others) and also adding pcie_aspm=off to the flash/boot section in the UNRAID GUI and test GPU passthrough again? I have read reports that this may resolve the D3/sleep issue and allow us to reboot VMs without having to reboot the host. If it works, could be an acceptable workaround until the wider problem is resolved.
  2. Ryzen Threadripper Platform Issues

    How are you getting on with the Zenith board and UNRAID? I just bought this board but concerned with the reports of GPU/PCIe passthrough issues.
  3. Anybody planning a Ryzen build?

    From experience, the hand-off/ device reset issues have only ever plagued me with Gigabyte boards since they are the very few that allow you to choose a PCI-e slot as Primary display. Having said that, the reset issues affected my Samsung nvme when passed through to a VM and not the gfx card.
  4. Ah, I see, that's good to know. I did read somewhere that hypervisor.cpuid.v0 = FALSE disables certain performance enhancements within the W10 VM so I was reluctant to use this parameter. How about temperature monitoring? What does ESXi / vCenter show in terms of temperatures for your devices?
  5. I thought nvidia passthrough was a no go with ESXi? Also, ESXi does not show temperatures for motherboard etc?
  6. Bugger that. I pulled the trigger on an Asus Zenith Extreme x399 but not on a processor yet. I'm thinking of whether to return it and go x299 to avoid all the TR4 passthrough issues... Advice?
  7. As an added tip I would also consider using direct passthrough for your SSD/NVME drive to the Windows 10 VM. In the past, whenever I provisioned a W10 VM using vfio scsi driver / raw image, i ran in to random audio 'crackle & pop' issues even when using msiutil. Passing through an nvme meant i could also use samsung nvme driver for optimal performance.
  8. X299 Gpu Passthrough issue?

    Hi - Speaking from experience, one of the very few boards that allow you to select which GPU to boot from are the Gigabyte boards. I had one on the x99 platform and it could do this but I ran in to issues with nvme passthrough. AFAIK there is no way to force UNRAID to boot from a specific GPU unless the BIOS has this feature. Alternatively, use the 1030 in the 1st PCIe x16 slot.
  9. UNRAID & Threadripper

    according to this post - https://community.amd.com/message/2823396#comment-2823396 npt issue can be resolved by switching IOMMU to enabled and not 'auto' for threadripper. Can someone try this and confirm?

    Really? And this hack works with 1080ti and 6.5u1? What are the drawbacks of this hack in terms of cpu/vm performance?
  11. Anybody planning a Ryzen build?

    I would switch to vmware esxi in a heartbeat if temperature monitoring for most mobo components and nvidia geforce passthrough worked.

    For anyone wondering if NPT issue is also present with threadripper, the answer is yes. Im probably going with intel once the prices drop a little.

    Cool. Let us know your 3dmark bench scores particularly the fire strike physics and combined since that is severely impacted by the NPT issue and Ryzen. Where did you purchase from if you don't mind me asking?
  14. Hello I have been reading many reports from various sources regarding the NPT issue with Ryzen and GPU passthrough. Many (including myself) are frustrated with the poor GPU/CPU performance exhibited in either ntp=0 or npt=1 modes. No-one from Linux KVM dev teams from what I can tell has acknowledged there is an issue and that it is being looked at, this is extremely worrying especially with Threadripper just around the corner. I would be interested to hear the techie's thoughts from Limetech regarding this problem. Maybe someone has good connections in the KVM dev community and can possibly give us a positive update on this problem? I'm sure the UNRAID faithful would welcome some update/news either way. Thank you.
  15. Anybody planning a Ryzen build?

    Wait until it's confirmed that npt issue that's plaguing ryzen owners is not present in threadripper. I have no idea if it's being looked at tbh and like you I'm very keen on TR.
