That's interesting, @dkerlee. Thanks for the insight on both fronts (the docker updating and your experience with a VM), and your intent to update it at some point. Much appreciated! I'm pretty content with the Roon server's functionality at the moment so there's no reason I would want to update it right now. My main concern is the prompt on the client side to update which could potentially break it. If there was a way to disable that completely, that would address my concern.

Greetings! Is the best approach here to run Roon in a linux VM as opposed to a docker image in unraid, or am I ok as-is? I have mine running in unraid as a docker (installed "steefdebruijn/docker-roonserver" under community apps for unraid - thx Steef!), but am being prompted to update via the client end on my phone/tablet. I decline the update prompt each time as I'm reading here it can break Roon server-side and render my current backups useless. Someone in my household will likely inadvertently click update and break my Roon server install so I want to prepare for that. I see that an update hasn't been rolled out for this docker in over a year so don't know if this will be maintained (wish I had the skills myself to help with this), or if I should pivot to something else long term. I'm willing to start over with a Room streaming platform where I likely won't lose our play history, playlists, etc. if something goes sideways and I have to restore Roon backups. I've been looking at doing a linux VM for Roon, maybe a NUC dedicated for it (roll my own with ROCK), or just bite the bullet and buy a dedicated streamer to reside in my A/V rack (Aurender, Lumin, Innous, etc.). Any suggestions from experience?

I hope it works for you. I didn't have stability long enough with turbo on to properly run CPU benchmarks. I'm not sure what the performance consequences are with it off other than not having the turbo speed of 5GHz as opposed to the base clock speed of 3.7GHz for the E-2288G. It's likely substantial with 8 cores/16 threads. I hope Intel/ASRock comes out with a fix at some point so we can run it full throttle. 🤞

Yes. Disabling turbo for the Xeon E2288G in UNRAID via the Tips and Tweaks plugin resolved it for many of us.

That would be great if it came out officially, but 2.3 came out in April. I recall installing it initially and had no access to the iGPU for HW transocding until I installed their beta BIOS (2.21a). https://www.asrockrack.com/general/productdetail.asp?Model=E3C246D4U#Download

I had a NVMe SSD installed in my board along with a 12TB SATA HDD on SATA port 0. Both detected in the BIOS and unraid. I could write to the 12TB HDD, but didn't try to on the NVMe SSD. I have since removed the SSD since it was small and of no use to me. Perhaps both the NVMe slot and SATA port 0 are usable concurrently? That would go against the ASRock documentation, but pretty cool if true nonetheless. I need to get me one of those H310s as I'm already running 8 drives. I suppose I could Velcro my SSDs within the case and run them cabled, freeing up a few 3.5" hot plug carriers for big spinners, and/or use the 5.25" bays for 3.5" spinning drives with a SATA pass-through adapter if needed.

Just to give fellow users of this HW who might be dealing with random CPU_CATERR lockups too, the recommendation to set "Enable Intel Turbo" to "No" in the tips and tweaks plugin for unraid has given me the longest run of stability so far (no lockups and I'm running all of my dockers, and a VM full clip). If this continues, I'll be quite happy with the HW upgrades; just hoping for a long-term fix from whoever is the root cause of this (Intel, ASRock, someone else?).

I was eyeballing the Quadro P2000. If I can't get the iGPU going for QSV, that will be my plan B. Are these the best instructions to follow after flashing my BIOS to enable the iGPU in unraid and assigning it to my Emby container for quick sync (will just switch Plex for Emby in the instructions)?

I just realized that now. Thank you!

Good luck on the stress testing. Hopefully, one day, we can go full bore with this setup without any stability issues. I installed the tips and tweaks plugin so I could disable turbo boost in an attempt to avoid these intermittent lockups and CPU_CATERR errors. *fingers crossed* Can someone hook me up with the latest beta BIOS version that allows me to use the iGPU for QuickSync? I was hoping to drop my prior discreet GPU in this setup (650Ti BOOST or GTX 980), but the Silverstone CS380 case I bought won't accommodate their length (iGPU transcoding to the rescue!). Now I'm having buyer's remorse on the case over the Fractal Design 7XL or even the Node 804. Both have much better cooling options as well. @kaiguy I've gotten the 5 beep warning at random during POST as well. No idea what that's about as it's headless and my system works in unraid minus the intermittent lockups followed by the CATERR_CPU errors generated in IPMI reporting (hoping disabling turbo boost fixes that). Hoopster, how do I link a user so they're notified when I mention them in a post like you did before with JM2005 and LateNight? I though the "@" symbol would do it for "kaiguy", but I guess not.

Greetings, Hoopster. First off, thank you for being the trailblazer for this specific unraid build and to everyone else who has shared their experiences on this thread (read through page 8 so far). I pretty much bought your same setup minus my drives are 12TB WD Reds. I must say, IPMI is so refreshing. Having that kind of insight and control on a hardware level is really handy! I was originally running unraid on an ASRock P67 board and Intel i5-2500k with 16GBs of RAM (my old gaming rig being repurposed for data hoarding :)). Did that for a few months very stably and made the decision to go with more horsepower and scalability. After doing some research, I came upon your build and thought, "This is exactly what I need!" I bought my package from IMC on eBay as you had done. Really a helpful, honest and all around nice guy. Having the ASRock E3C246D4U rack board with an Intel Xeon E-2288G and 64GBs of ECC RAM offers some much performance overhead (hoping for more stability)! With that being said, the transition to the new hardware worked pretty flawlessly thanks due in part to the brilliant software engineers at unraid, but I'm having the same intermittent lockups as you (over a dozen in the last 3 days). IPMI logs the event as "CPU_CATERR | Processor | State Asserted - Deasserted"). I've had them occur when the unraid server was virtually idle (was just pre-clearing a 12TB HDD overnight) and it locked up with just an hour left of the clear (had to turn the server off and reboot it through IPMI). I've since attempted to re-pre-clear that same drive over 6 times. Seems like I can't stay stable long enough to complete it as the intermittent lockups plague me. Running fold@home definitely accelerates the lockup, but my temps don't seem high enough to cause this lockup. The PCH, board and CPU don't get above 76C per the probes reporting in IPMI. Running Emby and a nearly idle Windows 10 VM results in the lock up from anywhere to 15 minutes in to nearly 2 hours of direct streaming a movie through Emby (no one else on the server at that time). You would think IPMI reporting would flag a thermal event if that was the root cause, but all I see in the log are CPU_CATERR events that coincide with these lockups. I have since remove my heatsink, reapplied thermal paste and reseated the heatsink along with the power connectors to the board and did a spot check of the rest of the hardware. No idea what is causing these intermittent lockups. I'm in contact with IMC through eBay who has a ticket in with ASRock already. By the way, can you send me that beta BIOS so I can flash for HW transcoding with the iGPU? Transcoding one 1080p remux to 5Mb has me running at nearly 75% CPU utilization which seems super high for a Xeon E-2288G, but maybe not? Not sure why this feature isn't already unlocked with a current public BIOS release. Yikes... so I just read above me (only through page 8 of this thread so far) and it seems I'm not the only one getting lockups with CPU_CATERR errors intermittently. So, it appears I need to disable turbo boost? Seems counterproductive when we bought the top bin Xeon for this application.

Hi Ich777, First off, thanks for helping us gamers who want to serve on unraid. Your work on these dockers is very much appreciated! Bare with me as I'm pretty technical in the windows arena and with client and server hardware, but am quite a neophyte with unraid/linux in general. Like many others who love the low low price of free, I installed Ark Survival on Epic as opposed to Steam because it's hard to say no to free (Steam, wanted $50 for it). I played it with a friend on a non-dedicated server and we decided to setup a dedicated server. Well that turned out to be quite a chore in windows and so I checked community apps for a docker and boom! I installed yours. I can see it under servers in Steam (under view | servers | LAN), but can't when running Ark Survival in Epic (chose unofficial servers and see password protected servers). I have the ports needed to run the dedicated server forwarded on my router for my unraid server, but I don't own the game on steam (I left the steam credentials blank when setting up the docker for the server). Do I need to own a client copy on steam in order to join my hosted server via your super helpful Ark Survival server docker container on unraid? Is there a way for me to host this game in your docker and see it with an Epic client install of Ark Survival? We can continue to play via an un-dedicated server in windows through Epic on Windows 10, but like the idea of a perpetual server running regardless if my gaming PC is on or not (plus Linux FTW!). I suppose I could create a Windows 10 VM and tinker with running a dedicated server that way on top of unraid, but like the low overhead and reliability of running it via docker if possible. Thanks again for your work on this thus far! Thinking on this further, if steam only shows my docker server under LAN, does that mean the game isn't being seen outside of my network? I had the ports open on my Windows 10 gaming system and we managed to connect to one another remotely (we had hamachi off) and it worked fine that way through Epic via a non-dedicated server. I moved those port forwarding rules to my unraid server's IP to no avail. -Neil
