Microserver Gen10 CPU limit

Recommended Posts


Hi, I have an HPE Proliant  Microserver Gen10  x3216  with ubuntu server installed. 


Recenty i decided to check my CPU frequency (in ubuntu and in the EFI) and i realised that it only runs at 1.6Ghz max even though specifications claims that it can go up to 3.0Ghz.

Do you know if there is something i can do about it? I´ve already called HPE to ask for help but the only answer i got was "we do not support overclock" even though it´s not overclock because the values are withing the factory limits that they claim it can work.


I tried to make several stress test and put the server under heavy CPU loads but all i can get is 1.6Ghz.


Sorry if i made any mistakes , english it´s not my first language.

What did you use to stress test it?

Stress and cpuburn,  in single and multi thread mode. I´m aware of this AMD CPU limitations regarding CPU boost when all cores are active.

I did a little research and the issue seems to be related to AMD CPB(core performance boost),  when all cores are enabled the CPU doesn't enter in boost mode, only enters when 1/2 or less of the cores are idle.

Good research, good to know. I would have expected it to enter boost regardless of cores active.

On my Windows Server 2016 Gen10, my X3216 (2 core) CPU cores run between 2.1GHz and 2.5GHz when I stress it with Prime95! Consider that the Graphics cores are not used, so its TDP allows the boost... In all other (less stressful) scenarios both CPU cores go to 3.0GHz easily.

CentOS 7.4 , amd-gpu drivers installed , x3216 CPU

[itx@localhost ~]$ sudo cpupower monitor
    |Mperf               || Idle_Stats         
CPU | C0   | Cx   | Freq || POLL | C1   | C2   
   0| 87.85| 12.15|  2863||  0.00|  9.28|  3.26
   1| 88.97| 11.03|  2831||  0.00|  8.20|  2.69
As you see 2.8Gz CPU freq under load (loading Oracle 12)

So, Any idea now? Do you fix it ? I have same question too.

I found this issue since I used ESXi virtualization platform and now I switch to Debian 10 physical machine. 

I try install Windows 10 on my HPE MicroServer Gen10 which CPU is AMD X3216, turbo works well and CPU freq up to 3.0GHz.

BUT in ESXi and Debian10 ,CPU has been limit by BIOS up to 1.6G default freq which found in /sys/devices/system/cpu/cpufreq.

I try install GPU drive and firmware and nothing happen, it not work.

      As I have decided to make some improvements on my afermarket fan controller I am trying to try implementing thermal control or mobo PWM control of additional fans, but before that I'm in a great need to inderstand how much fan count the controller should be ready to support. As this forum doesn't support polls I have nothing to do but ask you to reply on this topic.
      What I would be thankful to know:
      1. How many fans have you installed in your Microserver.
      2. What fans do you use (size, 3/4-pin connector) and where are they located, also what are they cooling.
      3. What way do you power these fans?
      Thank you in advance for your feedback!

      Hi everyone.
      New to this forum.
      I have a gen8 microserver running at home, where I have installed an SSD in the ODD sata slot. On the SSD I have installed Ubuntu Server 18.04.
      I have then created a logical volume witht the raid controller and can then boot to the SSD. So far so good.
      My problem emerges when I reboot the system. The logical volume disapears and it gives the error: "boot logical drive is configured but is missing or offline".
      I then have to go into the utility and reconfigure the logical volume. Kind of annoying, when trying to run a headless setup.

      Good day all
      i bought a gen 10 x3216 MicroServer and I have been trying to install windows server 2016 on it with a usb and I get it to boot into the usb with the iso on it but I can not get past the one install step where u supposed to select the drive.
      instead it says to download storage drivers and browse to select driver. I have downloaded every single storage driver from the hpe site or is sure does feel like it.
      if I try to select the driver I have to do so manually by unticking show only compatible drivers because if I leave it ticked there is nothing compatible. Iam stumped on what the correct driver is.
      ok so what Iam trying to do isssssss I want to install the os onto the usb that I have attached inside the box the one that is directly coming off the board. Is that a different driver ? 
      In bios/boot up options I can see all usb connected.
      can anyone please help me with this

      I'm new to the HPMSG8 world and so far I'm loving it. I have a stock Xeon with 16G of aftermarket memory with iLO patched to 2.70. Next up is adding a RAID card, so I can put my boot SSD on the onboard RAID. I picked up a LSI SAS9211-8i on Amazon, but am struggling to flash it to IT mode on the MicroServer. Is this even possible? Unfortunately, the only other system I have with PCI slots is 32-bit.
      Any pointers would be greatly appreciated.
