Works well with AMD HD series, assuming is an issue with the reset bug. Not confirmed.

Changed Priority to Annoyance

No haven't tried, got tired of AMD 5600 GPU series reset bug. Got back to the HD series, works like a charm

Hello all, Same here with the x470 gaming pro and ryzen 2700. Downgraded from v19 to v17, solved the issue. Cheers

Similar issue with AMD Radeon HD 7900 series. Right after installing latest compatible drivers from AMD ( auto compatibility tool) the screen blacks out. Works by removing GPU pass-through, VNC into it, use DDU to remove GPU driver. Start again with GPU pass-though and installing older version of the Radeon Software V17.1.1. Working so far.

I cannot help you with the load requirements, relative to the mem i dont think ECC would be reasonable for a Ryzen 2. To take full advantage of all those cores you need fast mem (>2.6GHz). As far im aware fast ECC DDR4 does not exist, if it does, it will be bloody expensive !

Hello, Never had a cpu scaling driver, dont even know how to do it. Regards.

Hello all, Just another quick update, if i disable all the load from my last 8 vcores, then i see the cpu frequency going down and staying down around 2ishGHz (no cpu scaling driver). Pointing to the linux scaling driver is artificiality slowing down/up the core frequencies (as Ryzen 1 users reported), overriding the Ryzen PBoost curve. Regards

Hello Paul, Yes i understand, is it possible for you to disable all but one core on the bios, and give it a run with unraid. That test would definitely put this doubt of hardware/software to an rest. Ideally keep active your best core. Also here is a command to watch the frequencies update every second: watch -n1 "cat /proc/cpuinfo | grep MHz" With the previous command i can see that even with a very small load 2 to 5% my cpu speeds on all cores over around 4GHz, dropping sometimes to 2ishGHz, that points that at minimum effort unraid does in fact spreads the load. Regards

Hello all, Relative to the subject of Ryzen 2 oc vs Ryzen 1 oc i believe the next graph shows the reason: Ryzen 1 users are reporting on unraid only getting 3.7Ghz max, that kind of make sense since unraid (when loaded with other stuff, mainly vm) will always use more than 2 threads. One way you guys can test this is to unload everything from unraid, and do cpu stress test on unraid itself and check if 1 or 2T can boost to 4GHz (if unraid does not spread the load anyway). This would have to be done as Paul proceeded in removing the Linux CPU Freq scaling driver (as i believe is useless with Ryzen). Also we would need a better way to benchmark instead of getting only instantaneous GHz reading with grep it would be great to get session min/max/avg readings, dont know if that command exists, but it can be created with the grep command in a script file running @ lets say 10ms or even less if possible (it would be handy). If this is the case then its actually a good sign Ryzen 1 users cannot reach 4GHz, meaning unraid is spreading the load evenly across multiple cores, opposite to windows ... The data that i get in Ryzen 2700x both on unraid and on bare-bone windows 10 matches in perfection the previous graph and i can even see on windows (using hardware monitor) a session max close to 4.35GHz in some cores with the stock cooler. On unraid max that i could spot using grep was around 4.25GHz. Regards.

Hello all, Paul running the cpufreq-info i get the following (on all cores): Ill try to dig into this a bit more over the weekend (post some bios screenshoots), but basically its all defaulted, yes SVN is on (or no vm), default was inactive. I believe (not sure) the boost is all done in firmware nothing to do with the OS, at least on Ryzen 2. It may well be the XFR2 because its more linear (more resolution/interpolation) it scales better on a linux OS. Windows may push XFR1 to max but not linux (just wondering) ... And im using CPU Scaling Governor: Conservative on the unraid. Changed it to performance but did not notice any change (but cannot guarantee as i was just trying to spot changes using the grep command) ... Regards

Hello all, Recently i upgraded my intel i5 gen 4 platform to an ryzen platform: AMD RYZEN 7 2700X sAM4 +Wraith 16GB 2x8GB CMK16GX4M2B3000C15 MSI X470 GAMING PRO Mobo Ive been using unraid with my i5 gen 4 for more than 2 years now without any issue. And im very pleased that the upgrade was seamless. After connecting the new hardware to my 'old' cache ssd array and hhd storage array and using the same unraid pen drive image, everything booted without issues. I have running on top of the unraid os (v6.4.0): krusader netdata pihole 2x tonido cloud server 2x windows 10 vm with dedicated gpu bunch of user utilities On the bios (latest version) did left it almost at default settings. XFR enable ( mem running @ 3GHz ) , AMD cool and quiet enable ... So all ryzen firmware oc features are enable and working well, the grep MHz command shows cpu core speed varying from 2.2GHz up to 4.25GHz Relative to power consumption i have not noticed any relevant change. The system is currently up and running for more than 3 days, no issues. The only downside i have up to this moment is not knowing the system / core temperatures (x470 is still very recent), fan speed is looking good (not worried about it, great stock cooler ). Here are some prints: Regards.
