ent44 Posted February 9, 2017 Share Posted February 9, 2017 So I ran Common problems plugin (lovely plugin) and it gave me this error, I've seen some other people have it but every problem seems different. Would love some help, here is my system info Model: Dell R710 M/B: Cisco Systems Inc. - 0YMXG9 CPU: Intel® Xeon® CPU L5630 @ 2.13GHz HVM: Enabled IOMMU: Enabled Cache: 128 kB Memory: 64 GB (max. installable capacity 288 GB) Network: bond0: fault-tolerance (active-backup), mtu 1500 eth0: 1000 Mb/s, full duplex, mtu 1500 eth1: 1000 Mb/s, full duplex, mtu 1500 eth2: 1000 Mb/s, full duplex, mtu 1500 eth3: 1000 Mb/s, full duplex, mtu 1500 Kernel: Linux 4.9.7-unRAID x86_64 OpenSSL: 1.0.2j Uptime: 1 day, 17:25:17 Close CPU possibly will not throttle down frequency at idle Your CPU is running constantly at 100% and will not throttle down when it's idle (to save heat / power). This is because there is currently no CPU Scaling Driver Installed. Seek assistance on the unRaid forums with this issue Link to comment
John_M Posted February 9, 2017 Share Posted February 9, 2017 There's a 9-page thread on the subject here. I don't know if it will help you because I haven't read all of it but it might show you how to do some tests. Link to comment
clowrym Posted February 9, 2017 Share Posted February 9, 2017 I have this issue as well with my dual Xeon processors, havent found a fix yet, none of the things listed in the thread posted helped me!! Link to comment
John_M Posted February 9, 2017 Share Posted February 9, 2017 Ah, well! It was worth a try. At least it's stuck on max - the way it always used to be - rather than min. Link to comment
ent44 Posted February 9, 2017 Author Share Posted February 9, 2017 Doesn't that mean it'll use full power? Or am I wrong there? Link to comment

ent44 Posted February 9, 2017 Author Share Posted February 9, 2017 Sorry, had a long day is this problem related to unRaid or to any software? Link to comment
John_M Posted February 9, 2017 Share Posted February 9, 2017 No. It's something about your CPU and Linux, I suppose. For example, the same version of Linux has no problem scaling the clocks of other models of CPU. Perhaps there's a hardware fault in that particular model that hasn't been worked round. The result is that it runs at full speed all the time. It doesn't much matter and there's not much chance of it being fixed as that particular model is End of Life according to the ARK so there's no point in worrying about it. Link to comment
ent44 Posted February 9, 2017 Author Share Posted February 9, 2017 That's a real shame because my CPU usage is never over 40% ish, so I waste a lot of power. Might convince me to swap my Plex to my R420 Link to comment
1812 Posted February 9, 2017 Share Posted February 9, 2017 does the r710 have any secondary power management? on hp products, it is iLo. I ask because there are power management settings in there that could be set to performance vs something less energy consuming even if there is no cpu scaling driver installed. also your bios may have similar settings....

ent44 Posted February 10, 2017 Author Share Posted February 10, 2017 I totally forgot about that, I'll try to find the setting in my iDrac. I'm going to upgrade my firmware to the latest version too, might help the issue. Link to comment
ent44 Posted February 11, 2017 Author Share Posted February 11, 2017 It worked!!! I've updated the firmware (twice!) and god... my versions were outdated... I think this didn't solve the problem with the firmware but it helped (http://i.imgur.com/mgdvLxA.jpg) Now thanks to user 1812 (thanks lad) I remembered I set my power management to max performance (I don't know why) but when I changed it from "max performance" to "os controlled" my CPU is idle-ing down. My server went from 150W idle to 120W idle, great improvement IMO. I made a shitty photo of my screen so people can find this option, if you boot up the server > press f2 > power management > "os controlled" (http://i.imgur.com/N8SGbzZ.jpg). And I regret I didn't get an enterprise iDrac for my server because I had to sit in the shed for 2 hours and it's snowing outside... Really grateful you guys helped me out :^) Link to comment
guru69 Posted July 13, 2019 Share Posted July 13, 2019 I had the same message from Fix Common Problems on Dell Precision T5500 with dual Xeons. The issue was that "Intel Speedstep Technologies" was disabled in the bios. All good now! Link to comment
