This will have the intended effect of the previously suggested command, with the main change being the name of the configuration file.
gksudo is suggested instead of sudo however is tangential to the problem, gksudo has the effect of sudo but is recommended for graphical applications such as leafpad due to greater "awareness" of environmental variables. Again this is tangential.

For determining the contents of a directory in the terminal use "ls". For example: "ls /etc/default", will list the contents of "/etc/default". Including files and directories. "ls" with no options will largely present the same information as a graphical file browser. Options for "ls" can be found by "man ls" the manual for ls.

When editing "/etc/default/grub" change GRUB_TIMEOUT to be equal to 0. Then "sudo update-grub"

If there are multiple kernels in the grub boot directory or operating systems detected this may be unsuccessful. If so change "GRUB_TIMEOUT=0.0" and "GRUB_HIDDEN_TIMEOUT=0.0".
Aside from the aforementioned configuration file, GRUB is also configured by the contents of the /etc/default/grub.d directory. When multiple kernels are detected a script "30_os-prober", disallows GRUB_TIMEOUT to be 0 and resets the value to 10 seconds. The idea being with a choice of kernels or operating systems to choose from the user would wish to choose which one to boot. Setting the values to decimals, alters the way this script interprets the values and should allow for GRUB to be hidden. When GRUB is hidden it can be accessed by depressing the SHIFT key on boot.

Also bare in mind a stable overclock in Windows is not necessarily stable in Linux but for system monitoring lm_sensors is a popular option, however I doubt it is comparable to HW Info.

All right!! Thank you very much, +REP! It worked!

Specifically, your suggestion with the decimals worked. A single zero did not do the trick. So, now I am booting like I used to, before the kernel update: after pressing F11, in my dual boot system, I boot directly into Mint, without any screens and options. I have pressed the SHIFT button, the three times I've rebooted, but I've never managed to get the GRUB menu. But I do not care. smile.gif

- How come and GRUB is still remembering the other kernels, since I have uninstalled them?

- Kind of a confusing screenshot:



It is very unfortunate that a good monitoring tool for Linux does not exist frown.giffrown.gif
I have heard about lm-sensors and tried to make them work on my system without any luck... It is for sure that I don't know how to make it work...

How are overclockers testing their Linux systems?

It's been a while since I've edited that file. Was close on the path rolleyes.gif

Did you first run sensors-detect and answer yes to everything then reboot and try sensors?

Yes, I have done that.

Here is what is shown, currently, on my system:
Warning: Spoiler! (Click to show)


Now...What is the problem with this?

1) Plenty of arbitrary / erratic values! For example, VCore = +2.04V ?!
2) These values are static! I am having the terminal right now open in my second monitor and nothing is changing. Nothing is measured in real-time.

So, how does this work?

I don't know IF this matters but right now I am on my per-core OC of x50 x50 x49 x48, with Adaptive Core voltage = 1.4V, in the BIOS.


EDIT:
Okay, I have some interesting results, at last! smile.gif

I have detected the sensors again, replied YES to everything, rebooted and then run Psensor, a utility I have already installed.
Here are the results: Warning: Spoiler! (Click to show)


Very nice, and I know how to modify and hide the erratic values in Psensor, so it's good! The only (serious) problem, though, is that Psensor does not show any voltage values...
What can I do about this?

Use the command:
Code:
watch -n 1 -d sensors

It will update every second and highlight the changes.

Thank you @Diffident, interesting idea. I have tried it. Unfortunately, it shows my VCore completely out of line, it shows it raising up to... 2.04V (lol), it does not report ANY other voltage - please, look at a screenshot of HWiNFO64 above to see the amount of V reported by my mobo - and finally, I cannot scroll down to view the second sensor.

Anyway, here is what I am currently using to monitor my system, a bit.
Warning: Spoiler! (Click to show)


That is all I have managed so far. I still need to hide some values in Psensor and also reorder them, but it is fair enough. Oh, and Psensor does not / cannot remember its position (on my 2nd monitor), neither the way I set it. So I have to move it and maximize it on each boot...........

The huge problem is that I have not yet discovered how to monitor Frequencies (clocks) and Voltages...

System monitoring is unfortunately an area where Windows is greatly superior to Linux, sad to say. If you think it's bad on an Intel system, you should try doing it on a machine with an AMD A88X chipset. LM-sensors detects almost nothing, even using the newer Linux kernels in Mint 18. I had already tried that by using the custom 4.4.0 from Exton Linux in Mint 17.3; the kernel worked fine but still no sensor support.

If I want to monitor anything, I just boot Windows 10. Only way to do it.

I've upgraded both my desktop and my laptop to 18, but I found a serious regression in the 4.4.0-28 kernel on my laptop. The sleep function turns off the display but fails to put the CPU into a low-power state. I closed the lid on it and the laptop was running hot when I opened it the next day, and did it repeatedly in tests. The original 4.4.0-21 was OK, and so is 4.6.0-exton, which is what I'm running on both machines now (although you're on your own if you do that, the Exton kernels are unofficial). Both 4.4.0-28 and 4.4.0-31 from the official repositories seem to do a very poor job of CPU scheduling and power management in general (probably why they're "category 5" updates and not installed by default). On 4.4.0-31, my laptop ran at 3068 MHz about half the time, even when idling, and the desktop would run at 4200 (current OC speed) when doing almost nothing.

Really-really sorry to hear all this, especially for the lack of appropriate monitoring utilities! frown.gif
And I believe you because I keep Googling but I am not discovering anything... frown.giffrown.gif

- What are the Linux overclockers doing?! How are they testing and stressing and monitoring their systems?!

What you said about Power consumption alerted me so I have just checked this by observing my Kill A Watt. My entire system (see sig_rig) + my Modem-Router + my Hi-Fi Amplifier (currently powered down) is connected to it. I am using two monitors. My results:

Per-Core OC: x 50 x50 x 49 x 48, cache x 44, Adaptive VCore = 1.4 in the BIOS, ALL C-States Enabled.

Windows 10 Pro
Sleep = 14 W
Idle = 116 - 120W

Linux Mint 18, kernel 4.4.0-31
Sleep = 14 W
Idle = 116 - 125W

The only thing that I have observed is that on Linux I also had spikes up to 150W. I am not sure however what the OS (Linux) was doing. I had the System Monitor opened and it was showing 1-4% usage on one core, different each time. In both situations, on idle, I was not touching the mouse at all.

Not sure (at all) how "professional" my testing was, but at least I am sure that on Sleep my system behaves the same in both OSes.

PS_1: never had a laptop, never will own one.

PS_2: HOW were you able to see the frequency you mention, on your laptop?! I do not know any way to see my current frequency! How did you do it?

If 4.4.0-31 works for you, stick with it. Most regressions occur on hardware that's not all that common anymore. I don't think Ubuntu would have pushed it out at all if it hadn't worked in internal testing. Both my older C2D-based laptop and my FM2+ desktop aren't all that commonly used, and probably much less so on Linux. And you don't even get 4.4.0-31 unless you accept the Category 5 updates, which most users wouldn't do. I just like pushing the envelope to see if I can get better performance, so I accepted it knowing that if there were any regressions, I could pull up the Grub menu and boot the older kernel (or install the Exton one, which I have).

I've always done stability testing in Windows. In my experience, Linux actually sometimes tolerates overclocks that Windows won't, so if my computer passes stability tests in Windows, I assume that Linux is stable until demonstrated otherwise. The only time I've ever had things go differently was when undervolting this 870K; there were some kernels that couldn't pull the CPU out of C6 under Linux, but Windows could do it at the same settings. I had to give the CPU a little more vcore or turn C6 off. This chip can run fine under Windows at stock speeds as low as 1.24v, but needs 1.30 in Linux because of the C6 issue. (I'm currently running at 4.2 GHz and 1.33v most of the time, in both OSes).

Windows was my primary OS until last fall, anyway, because my job at the time required Windows software. Since October, it's been Mint Cinnamon, but I still have Windows 10 as a dual-boot option on a separate SSD.

Okay, glad it works for you, and yes, I as well dual boot between Windows 10 Pro, my main OS currently, and Linux Mint 18. Until a week ago I was using my second SSD for the Windows Insider program but I got bored of it, and anyway I've already gotten a good idea about how the Anniversary (of Win 10) will be, so I thought to give Mint a chance. With all the Telemetry Windows 10 is using I feel the need to start familiarizing myself with, and learning, Linux Mint. Until I will be capable to perform in Mint 90 - 95% of everything I'm doing in Windows.

So, were you not able to monitor frequencies in Mint, after all?

My research has led me to this thread. That person has found a way to monitor voltages on his ASUS Z97M-PLUS motherboard. I am sorry to admit this but I do not understand or fully understand, almost anything mentioned in that thread!... frown.gif Not a native English speaker, either...

Right now I'm posting this post from Windows but when, on Mint, I give the command

cat /etc/sensors3.conf

as suggested in that thread, it says that I should visit lm-sensors.org and find a configuration file for my motherboard! Well...that site is down each time I've tried to access it! And Goggling has not returned ANY result about a configuration file for my motherboard. Lost...don't know what to do frown.gif

Most of the people here are gaming enthusiasts, which means they need DirectX and therefore use Windows. Hopefully, that will start to change with Vulkan getting more industry support than OpenGL ever had, but Windows is going to be with us for a long time to come as the go-to gaming OS.

The www.lm-sensors.org site has been down for months. Apparently, whoever maintained it not only stopped doing so, but also took down everything and disappeared without a trace, at least from the Internet. The most recent archive of the page that had the configuration files is this: https://web.archive.org/web/20150901092438/http://www.lm-sensors.org/wiki/Configurations Unfortunately, most of the ones there were very old to begin with.

I'm sure you know this already, but the best way to see what's supported is to simply type sudo sensors-detect from the command line and hope for the best.

I can monitor CPU frequency with Mint, that's never been a problem. The CPU reports its operating frequency correctly and I monitor it in real-time with Conky. But none of the advanced features work reliably if at all.

The link in that Ubuntu Forums thread: http://permalink.gmane.org/gmane.linux.drivers.sensors/36526 probably is your best bet as far as creating your own configuration file. At least there's information available. Good luck trying to find anything on how to do it with an A88X motherboard like mine.
