Safe Boot Intel Mac

[Terry Chavarin]

Sorecently I noticed in task manager my CPU speed is showing as 0.78 GHz, my processor is a 2.5 GHz. This shows as 2.49GHz in safe mode. I'm curious what the issue could be as it does not change from 0.78 no matter what I do.

This is the result of the power management capabilities enabled in your processor. The processor clock should move up to higher speeds as the processor is asked to do more work. When you say "no matter what I do", what did this entail? Try doing something like forcing Windows Update (or equivalent if running Linux) to run and you should see the clock speed increase...

So "no matter what I do" entails anything whether thats playing games etc, the speed does not change no matter what, I'm on high performance and I even set balanced and power saver to 100% mininum and maximum and it still hasn't changed.

Ok, next thought is to check whether this is just an issue with the (Windows) display of the frequency (there are reports of this kind of issue on the web). Download and run the Intel Processor Frequency Id Utility. The download page is here: -Processor-Frequency-ID-Utility Drivers & Software. Both Windows and standalone (bootable) versions are available...

I followed all the info supplied by the various manufacturers but mainly ASUS MB instructions and videos, the system fired up and works as expected with no issues except one very big issue that i cannot fathom, the CPU is fixed at 0.77GHz speed, that's 22% of the standard 3.5GHz expected from the "Intel I5 6600K", this is on the "ASUS Z170 Deluxe" MB with "G.Skill Ripjaws V Black 16GB (2x8GB) DDR4 PC4-25600 3200MHz Dual Channel Kit ".

I'm at a loss as to what is at fault, the speed limited to 22%, the BCLK at 100.2 x 8, the multiplier will not move of "X8" even though it has at best shown "x8 - 47" but still running at only "x8", CPU core V at 0.813 (i have increased this to 1.225V but exactly the same 22% on CPU). I have also tweaked many other values a little but as there was no response from altering these i have put all back to standard rather than make matters worse. I have reset CMOS and locked the 3200MHz memory to 2133MHz (2x8GB).

I am not an expert but i have built and repaired many computers over the last 15 years so I'm not new to this work but this one has got me beat. I believe there is a H/W issue with either the CPU or the motherboard but i do not have access to (or the money to buy new) another 1151 type CPU or motherboard.

I'm trying to install Ubuntu 20.04 alongside Windows 10 on my Acer computer. While trying to install Ubuntu, I was prompted with a warning about Intel's RST needing to be turned off. Following Choice #2 in heynnema's answer, I learned that I should:

That works, the option to change to AHCI is there. I haven't tried it yet because I was wondering if the bcdedit command proposed by heynnema does the same as following a) and activating safe boot through msconfig.

Hello. I am trying to fully disable Optane on my system. I have disabled Optane from the Intel Rapid Storage Technology app. I was hoping that this would disable Optane completely, but my SSD is still set to SATA Mode: "M.2/RAID Optane" in the BIOS. I want to change this to SATA Mode: AHCI. (My motherboard: -AORUS-PRO-rev-10#kf)

When I try to change this option, it persists even though I save changes. Now, there is one feature I haven't tried to change- In my BIOS, when "M.2/RAID Optane" is selected as the SATA mode, there is an entry for "M.2/Optane Genie" and "M.2_1/RST Pcie Storage Remapping". I can disable M.2_1 without issue. However, when I try to disable M.2/Optane Genie, I get this warning:

Now we see the extent of the problem. I can't back up the system. If I use a Windows utility to image the drive, I will need Windows to run the utility and restore it. Now if Windows is damaged when I disable the feature, how can I restore it if I used a Windows Utility!? But if I try to use a Linux-based utility like Clonezilla, the drive is unreadable, because Linux cannot mount the device.

1) Will changing the SATA mode even do what I want? I need an SSD drive that can dual-boot multiple OS's securely. Perhaps it's possible to install a Linux OS on the drive without changing the SATA Mode? (I suppose I can try this myself).

2) How great is the risk associated with changing the SATA Mode? Is this warning just there so Gigabyte can waive liability? Since I have disabled Optane in Windows, is it actually safe to change this?

3) How can I backup the system? I can't do it from within Windows, because if I lose Windows, I can't restore. I can't do it from Linux, becuase Linux can't mount the device. I don't have a drive big enough to clone it directly, but the Windows partition is itself very small. Perhaps there's a way to clone partition to partition? Clonezilla supports this... but it's Linux under the hood.

A good answer for any of these questions will be sufficent for me. If I can install Linux on the device without changes, good! If I can turn off the RAID and use it as an AHCI device, good! And if I lose the data in the process, it's OK if I can recover it and continue booting into Windows.

EDIT: Apparently reading further I ended up in this specific guide for my laptop model which does something similar (although not through command line but via the msconfig app)

Maybe the msconfig approach is easier on the user and to add to the RST guide.

Wherever you find your answer, please come back and make specific recommendations to improve the strings and images of the documentation to save other users the hassle you encountered.

The main article really needs to be updated with the steps in this comment. Landed on this after struggling with the steps in the main article and landing on the blue screen. I had to set my BIOS back to RST and get windows booted properly. I then updated the registry as suggested in the main article and then used the steps in the comments to put it into safe mode - ensured that the change to AHCI was successful - and then booted back to normal mode. Thank you for this!

Apple includes a Safe mode in its Mac startup options that can help you work out if a problem is being caused by software that loads as your Mac boots up. It's particularly useful for resolving issues that don't seem to be linked with a particular app.

Safe mode achieves this first by preventing software from launching during the boot process. This can include login items, inessential system extensions, and third-party fonts. It then runs a First Aid check of your Mac's startup disk and deletes some system caches that can be created again.

If the problem you're having still happens in safe mode, reinstall macOS and make sure that your Apple software and third-party apps are up to date. Likewise, if your Mac restarts several times and then shuts down while starting up in safe mode, the best course of action is to start again fresh and reinstall macOS plus any third-party apps you use.

If the issue returns after a normal boot, a startup item is the likely culprit. Make sure your Apple software and any third-party apps you use are up-to-date. If that doesn't solve the problem, try logging in with another user account. Alternately, try selectively deactivating your login items to narrow down the possibilities. The following steps show how.

I have a Dell Vostro with a 8th gen i7 and a Geforce MX130 and ever since I installed Windows 11 insider build I have come across issues. One HUGE one being that when I try to turn on my PC to log into windows, the log in screen shows as just black. I press enter... nothing. I try CRL+ALT+DEL... nothing. Just a black screen with a cursor.

Thanks @Ali_Aykut_Demir. You're spot on with an Intel Integrated Sensor Hub. I booted my Dell laptop to Safe Mode, disabled the Intel Integrated Sensor Solution and the black window with cursor problem is gone.

I solved this:

clean install with internet off.

installed the dell update and re-enabled the internet

installed the drivers proposed by dell.

disabled "intel integrated sensor solution"

updated the rest via windows update.

for now it is the only method to prevent the pc from giving problems.

@LeadingEd02

You forcefully shut down the computer during boot two or three times so windows will start automatic repair where you can access safemode to troubleshoot issues.

If you are unsure about exactly which steps:

Google: "windows 11 safe mode" - the articles there have step by step guides with pictures.

@DrTamizand others,

I have a Dell Vostro 5581 which has similar specs to yours. It already had all the latest Dell drivers installed through Dell Update/SupportAssist including most importantly the June 2020 Intel Integrated Sensor Hub Driver which supports both Windows 10/11.

I just installed Windows 11 as an upgrade over Windows 10 using a mounted ISO using the latest (as of 22 Nov 2021) released Win11_English_x64v1.iso file. I encountered the same problem as you. This is not a Windows Insider build - I am just posting my solution here as yours was the first post I found when searching for a solution, so hopefully others will find it too.

Building on some of the suggestions in the replies above, I fixed the issue by :-

Forcing the laptop into the recovery menu (pressing the power button to turn on, then immediately holding the power button until it turned off again multiple times over)

Booted to Safe Mode.

As the Start menu does not respond to the mouse/keyboard - Press Ctrl-Alt-Del and select Task Manager from the popup

Select File-Run new task and type devmgmt.msc - I cannot recall if the check box for [ ] Create this task with administrative privileges was available in safe mode but if it is there, check it

Expand System Devices

Scroll down and DISABLE "Intel Integrated Sensor Solution"

Reboot

The laptop should function normally now.

(If you have done a clean install of Windows 11, you will now need to go to the Dell Support web site for your model and download the Intel Integrated Sensor Hub Driver and install it. )

Open Device Manager again

Expand System Devices

Scroll down and UPDATE DRIVERS for "Intel Integrated Sensor Solution"

Select -> Browse my computer for drivers

Select -> Let me pick from a list of available drivers on my computer

The list showed two drivers for "compatible hardware" with the currently selected one being the incompatible "Intel(R) Integrated Sensor Solution"

Select the "Intel(R) Integrated Sensor Hub - 9DFC" driver (yours may have a different alphanumeric extension)

Apply the change

Reboot

All should be functioning normally with the Sensor Hub no longer disabled in the Device Manager.

The root of the issue seems to be that the installation is picking an incompatible generic driver for the Sensor Hub in preference to the Dell specific one, even when both are available on the system.

Hopefully that helps.
