Hey all, maybe a bit of an odd ask here. I'm in the market for a GPU for use in rendering and occasional gaming. My current budget has pushed me towards the used market, and I'm thinking 3080. I happened upon a Gigabyte 3080 Turbo Edition listed on craigslist near me for only $200 because it has an issue. It seems to me like it's either a relatively silly/simple thing to fix or hopeless. Basically under load the clock speeds are plummeting. Obviously I haven't purchased the card yet so my information and troubleshooting is limited, but I did get some pictures of the symptoms from the seller. The temps seem fine, but what does stick out to me is the power spike that appears to happen in line with the speed drop. Is this something anyone has seen before and could provide insight on a solution to? If not it's no skin off my back of course, I just won't purchase, but if it's as simple as a bios flash or some afterburner tweaking then it could be a great deal.

For the sake of completeness, I wanted to provide an update here for any future readers. Through suggestion over on the truenas forum and some experimenting with proxmox, we've narrowed it down to hardware limitations on such an old platform. Unfortunate, but I may have a workaround through passing through individual (not hot-swappable) USB devices rather than the entire controller with proxmox until I upgrade my hardware. This was only meant to be a temporary test bed I had laying around anyway... For anyone curious enough to see the truenas forum thread: Device Passthrough Error Operation Not Permitted | TrueNAS Community

I was just on the way to post there and probably try level1techs as well. Already had the account here though...

Before I start, I'll just get this out of the way: I know truenas isn't very highly regarded as a hypervisor for virtualization whether it be core or scale, but hey they're trying so I figured I might as well try too. If I can't resolve this issue after this forum post, then it'll likely be over to proxmox with truenas and other vms underneath for me... Anyway, onto the issue: I'm trying to get a VM up and running but having difficulty with passing through my USB controller. I finally got it separated out to a IOMMU group where it's all alone, however I now get a new error: Error: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/supervisor/supervisor_base.py", line 165, in start if self.domain.create() < 0: File "/usr/lib/python3/dist-packages/libvirt.py", line 1353, in create raise libvirtError('virDomainCreate() failed') libvirt.libvirtError: internal error: process exited while connecting to monitor: 2022-09-04T22:23:30.894130Z qemu-system-x86_64: -device vfio-pci,host=0000:02:00.0,id=hostdev0,bus=pci.0,addr=0x7: vfio 0000:02:00.0: failed to setup container for group 2: Failed to set iommu for container: Operation not permitted During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/middlewared/main.py", line 176, in call_method result = await self.middleware._call(message['method'], serviceobj, methodobj, params, app=self) File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1293, in _call return await methodobj(*prepared_call.args) File "/usr/lib/python3/dist-packages/middlewared/schema.py", line 1272, in nf return await func(*args, **kwargs) File "/usr/lib/python3/dist-packages/middlewared/schema.py", line 1140, in nf res = await f(*args, **kwargs) File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/vm_lifecycle.py", line 39, in start await self.middleware.run_in_thread(self._start, vm['name']) File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1208, in run_in_thread return await self.run_in_executor(self.thread_pool_executor, method, *args, **kwargs) File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1205, in run_in_executor return await loop.run_in_executor(pool, functools.partial(method, *args, **kwargs)) File "/usr/lib/python3.9/concurrent/futures/thread.py", line 52, in run result = self.fn(*self.args, **self.kwargs) File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/vm_supervisor.py", line 62, in _start self.vms[vm_name].start(vm_data=self._vm_from_name(vm_name)) File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/supervisor/supervisor_base.py", line 174, in start raise CallError('\n'.join(errors)) middlewared.service_exception.CallError: [EFAULT] internal error: process exited while connecting to monitor: 2022-09-04T22:23:30.894130Z qemu-system-x86_64: -device vfio-pci,host=0000:02:00.0,id=hostdev0,bus=pci.0,addr=0x7: vfio 0000:02:00.0: failed to setup container for group 2: Failed to set iommu for container: Operation not permitted I have no idea what to make of it and haven't been able to resolve with any of my googling and guide reading. The system I'm on is an old Dell T7400 (Xeon E5430) that should be fully capable of virtualization, and I've made sure to enable all of the virtualization features in the bios. Running TrueNAS-SCALE-22.02.3 As always, I'm sure I've left things out so let me know if there are any other specs or info you'd like me to get. Thanks in advance to any of you kind folk that may help out

I'm not very familiar with proxmox so I'll do some research into it. If you don't mind me asking, what are your biggest reasons for running it with truenas underneath as opposed to just running truenas natively? I know you mentioned more flexibility but so far from what I've read on both solutions I'm not sure I can tell much benefit there since truenas itself will allow running VMs.

Budget (including currency): ~$1000 Country: USA Games, programs or workloads that it will be used for: Storage server for backups, Hosting 3D print server (currently running fluiddpi), Occasional media streaming Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): I'm thinking about building a home server to store file backups, run my 3D print server, have connected to my TV for occasional media streaming, and generally be a test bed I can use to play with home networking setups. In the future I'll likely want to use it to host a VPN and run home automation. My current thinking is to get a Ryzen 5600G as the integrated graphics should be plenty good for what I want to do and the multithreaded performance would be decent for running docker containers for the tasks I want it to do as well as a usable Linux or Windows VM for the media pc side of things. I don't really need that much storage, but I figure if I'm going to build a home server I ought to improve my backup situation. Two terabytes or maybe even less with room for future expansion would be my target there. Read/write speed would be more important to me because I'll probably want to work directly off of it in addition to the backups for some larger projects. The only other big target for the build I can think of is having it be fairly small (Fractal Core 500 caught my eye but seems to be difficult to get), which of course will be a tradeoff with the room for expansion. Depending on how bored I get this summer I may try to wait for next gen ryzen to come out and drop prices or get an upgrade, but we'll see. To recap my current thoughts in a less word vomit format: CPU: Ryzen 5600G RAM: 16 GB DDR4-3600 OS: TrueNAS Scale

I went towards a standard tower pc build rather than something like a PowerEdge solution mainly for noise and standard parts reasons. It still looks like a decent option though.

Thanks everyone for the build suggestions. A lot of what you guys have recommended using falls in line with the list ideas I’d come up with, with the main difference I’m seeing is a more powerful cpu. If anybody could provide any more insight into freenas and its capabilities, is my goal of automated migration of old files to the hard drives reasonable?

I'm part of an engineering design team at my university (Formula SAE for those who may be familiar) that is constantly running into storage limitations with the amount of server space the school will allow us to have. They provide us with roughly 1.5TB while we currently use approximately 1TB every year. Our current "solution" is moving older files to various external drives where they then become next to useless and impossible to find. For a more sustainable solution, I've started looking into options for us to build our own NAS and customize it to best suit our needs. While I have experience with PC hardware and building, and watch LTT religiously, this is not my area of expertise so I'd appreciate some help from the community. Here's a quick list of the current goals I've come up with: 2-3TB of SSD storage for files being actively worked on and frequently accessed Another 10 or so terabytes of HDD storage for "cold storage" of older files that are less likely to be accessed SFTP or similar setup for remote access At least 3 Ethernet ports for connecting to the heaviest used computers (a switch may be used to connect to a few more lower priority systems) Ability to upgrade down the line to host at least one VM to offload some simulation (not a priority for now) Hopefully fairly inexpensive ($1000-$1500) And here are my thoughts on setup so far: ATX or Micro ATX form factor to use standard PC parts Ryzen 3200G (good price-performance and upgradability) 16 GB RAM 2 2-port 10Gbit/s network adapters FreeNAS OS (free and easy to use from what I gather) Having never worked with it, I'm not sure exactly the capabilities and requirements of FreeNAS. For instance, is there an easy way to automate offloading old files from SSDs to mechanical storage and would it allow us to set up VMs in the future? I'm probably completely overlooking several things as well. Thanks in advance for any advice and criticism
