Minisforum MS-A2 9955HX temperature fix

2025-07-02T03:03:19Z

Ddxfish: /* Alternative Configuration Testing */

'''Bottom Line:''' Testing revealed that the AMD 9955HX's default thermal settings prioritize maximum performance over longevity. Adjusting the TJmax setting from 0 to 78 in the UEFI reduces operating temperatures by 15 degrees with only a 5% max performance reduction while extending estimated CPU lifespan by approximately 800%. If you have this computer, you should change your TJMax.

[[Image:Minisforums-ms-a2-uefi-bios-tjmax copy.jpg|right|thumb|350px|Change TJmax to 78]]

= AMD 9955HX Thermal Performance Analysis =

The '''AMD 9955HX''' is a high-performance mobile processor that benefits from thermal optimization through BIOS configuration. This analysis examines the relationship between thermal settings, performance, and component longevity.

* '''Performance Impact:''' Only 5% reduction from default settings
* '''Temperature Reduction:''' Operates 15°C cooler (from 95°C to 81°C)
* '''Lifespan Extension:''' From approximately 1 year to 8 years under continuous operation

== Understanding TJmax ==

'''TJmax''' (Junction Temperature Maximum) is the temperature threshold in the BIOS that instructs the CPU when to begin thermal throttling. Reducing this setting from the default 96°C to 78°C creates more conservative thermal behavior, improving longevity with minimal performance impact.

== CPU Lifespan vs Operating Temperature ==

Higher operating temperatures reduce CPU lifespan through accelerated component wear. The following data shows expected lifespan for continuous 24/7 operation based on thermal research:

=== Alternative Configuration Testing ===

Various Windows power management options and BIOS settings were tested to compare effectiveness against TJmax adjustment. Windows Efficient required registry modification to enable the hidden power plan with "Efficient Enabled" option in Power Options control panel. Turbo Disabled used Windows Power Options maximum processor state set to 95%. Silent Mode, 75W, and 55W power limits were configured in BIOS/UEFI settings. Most alternative methods showed minimal thermal impact compared to TJmax configuration.

Minisforum MS-A2 9955HX temperature fix

2025-07-02T02:11:57Z

Ddxfish:

'''Bottom Line:''' Through systematic testing, I discovered that the AMD 9955HX's default thermal settings prioritize maximum performance at the cost of longevity. By adjusting the TJmax setting from 96°C to 78°C in the UEFI, the system runs 15 degrees cooler with only a 5% performance reduction while extending CPU lifespan by approximately 800%. This simple UEFI modification addresses a significant thermal management shortcoming in an otherwise excellent high-performance system.

= CPU Thermal Performance Analysis =

* '''Performance Loss:''' Only 5% reduction from default settings
* '''Temperature Drop:''' Runs 15°C cooler (from 95°C to 81°C)
* '''Lifespan Extension:''' From ~1 year to ~8 years under continuous operation

=== What is TJmax? ===
TJmax is the maximum temperature setting in the BIOS that tells the CPU when to start slowing down to avoid overheating - by lowering this from the default of 96°C to 78°C, we're essentially telling the CPU to be more conservative about heat.

== CPU Lifespan vs Operating Temperature ==

Based on electromigration studies and the Arrhenius equation, higher temperatures dramatically reduce CPU lifespan. The following shows expected lifespan for continuous 24/7 operation:

* '''Performance:''' Retains 95% of maximum performance (only 5% loss)
* '''Temperature:''' Reduces operating temperature by 15°C
* '''Longevity:''' Extends CPU lifespan from ~1 year to ~8 years under continuous load
* '''Efficiency:''' Optimal thermal design point discovered through testing

==== Key Insights: ====
* '''Thermal Optimization:''' Default 96°C setting prioritizes peak performance over longevity
* '''Sweet Spot Discovery:''' The 78°C anomaly shows better performance than 80°C setting, indicating precise thermal optimization
* '''Power Profiles Ineffective:''' Windows power management and BIOS power limits had minimal impact compared to TJmax setting
* '''Thermal Wall:''' Performance drops dramatically below 78°C due to aggressive thermal throttling

==== Server/Long-term Use: ====
With 78°C TJmax setting, this CPU is now suitable for server applications with minimal performance sacrifice and dramatically extended lifespan. The temperature reduction also means lower cooling costs and reduced system stress.

== What I Found ==

'''Bottom Line:''' Through systematic testing, I discovered that the AMD 9955HX's default thermal settings prioritize maximum performance at the cost of longevity. By adjusting the TJmax setting from 96°C to 78°C in the UEFI, the system runs 15 degrees cooler with only a 5% performance reduction while extending CPU lifespan by approximately 800%. This simple UEFI modification addresses a significant thermal management shortcoming in an otherwise excellent high-performance system.

* '''Performance Loss:''' Only 5% reduction from default settings
* '''Temperature Drop:''' Runs 15°C cooler (from 95°C to 81°C)
* '''Lifespan Extension:''' From ~1 year to ~8 years under continuous operation

=== What is TJmax? ===
TJmax is the maximum temperature setting in the BIOS that tells the CPU when to start slowing down to avoid overheating - by lowering this from the default of 96°C to 78°C, we're essentially telling the CPU to be more conservative about heat.

== CPU Lifespan vs Operating Temperature ==

Based on electromigration studies and the Arrhenius equation, higher temperatures dramatically reduce CPU lifespan. The following shows expected lifespan for continuous 24/7 operation:

{| class="wikitable"
|-
! Temperature (°C) !! Expected Lifespan (Years)
|-
| 50°C || ~50 years
|-
| 60°C || ~30 years
|-
| 70°C || ~18 years
|-
| 80°C || ~8 years
|-
| 90°C || ~4 years
|-
| 100°C || ~1.5 years
|-
| 110°C || ~0.5 years
|}

== Performance vs Temperature Analysis ==

Comparison of four different CPUs showing the relationship between thermal management and performance. The '''78°C anomaly''' on the 9955HX shows improved performance with lower temperature.

OpenGD77 - No audio in DMR mode when light is green (not receiving)

2024-09-10T15:12:15Z

Ddxfish:

I am using a gd-77 and a UV-380. OpenGD77 firmware 2024-05. Both are in DMR mode, tuned to a local repeater, and on the correct timeslot. The green light on the radio lights up, signal strength is high, but no audio. I tune to FM VFO without DMR and audio comes through fine. Still none on DMR. I did fix my issue, and this was how:

'''I pressed the talk button and started to hear stuff. I didn't realize I was not connected to Brandmeister channels until I hit the talk button. '''

==Ignore the green light==
Your green light indicating a signal does NOT indicate voice you can hear. It could be a user making a private call you can't hear. Basically ignore the green light in DMR mode on opengd77. Instead, use the brandmeister website to see if people are talking, then see if you hear it on your radio. Fewer people were talking than I expected, so I really thought DMR was broken, but it was not.

==Open filters menu, disable filters==

GD-77 has a button on the top.

UV380 press the S1 button above PTT and the OK button same time.

*Filter: none
*DMR Filter: none
*TS Filter: off
*CC Scan: on (tries to listen to all colors, optional)

==Do a parrot test==
After your filters are off, try doing a parrot test.
*Add a Digital Contact
**Private Call, 9990, Timeslot should match your repeater
*Add your repeater as a channel
**RX/TX, Color, Timeslot is your repeater info. Contact should be set to parrot. Empty TG.
*Tune to your channel and talk
**You should see "Echo Test" and a count while you talk
**You should hear your message a moment later

==Test your DMR via website==
This site displays active DMR connections and allows you to listen via the web. You are supposed to see your connection here when you make it.
*https://hose.brandmeister.network/
*https://brandmeister.network

*Add a new Digital Contact (echo test)
**Group Call, 9998, Timeslot matches your repeater
*Add a new channel
**Your repeater's RX/TX CC and TS. Set the Contact to 9998 echo test
*Tune to this contact, and open either brandmeister site (similar info)
*PTT and say hello while watching the website. You should hear/see yourself on 9998 echotest on this website

==Obvious steps==
*Check your channel
**RX and TX are often but not always offset
**TS is time slot, your repeater operator decides which timeslot it uses, so match that
**Color must match your repeater's color code
*Check your codeplug in Opengd77 CPS
**check your call sign is there
*Unplug the programming cable
**it wont output audio with it in
*Press the button to open a channel
**You cant just listen to stuff, you have to transmit to connect most repeaters to your desired channel

I am using a gd-77 and a UV-380. OpenGD77 firmware 2024-05. Both are in DMR mode, tuned to a local repeater, and on the correct timeslot. The green light on the radio lights up, signal strength is high, but no audio. I tune to FM VFO without DMR and audio comes through fine. Still none on DMR. I did fix my issue, and this was how:

==Ignore the green light==
Your green light indicating a signal does NOT indicate voice you can hear. It could be a user making a private call you can't hear. Basically ignore the green light in DMR mode on opengd77. Instead, use the brandmeister website to see if people are talking, then see if you hear it on your radio. Fewer people were talking than I expected, so I really thought DMR was broken, but it was not.

==Open filters menu, disable filters==

GD-77 has a button on the top.

UV380 press the S1 button above PTT and the OK button same time.

*Filter: none
*DMR Filter: none
*TS Filter: off
*CC Scan: on (tries to listen to all colors, optional)

==Do a parrot test==
After your filters are off, try doing a parrot test.
*Add a Digital Contact
**Private Call, 9990, Timeslot should match your repeater
*Add your repeater as a channel
**RX/TX, Color, Timeslot is your repeater info. Contact should be set to parrot. Empty TG.
*Tune to your channel and talk
**You should see "Echo Test" and a count while you talk
**You should hear your message a moment later

==Test your DMR via website==
This site displays active DMR connections and allows you to listen via the web. You are supposed to see your connection here when you make it.
*https://hose.brandmeister.network/
*https://brandmeister.network

*Add a new Digital Contact (echo test)
**Group Call, 9998, Timeslot matches your repeater
*Add a new channel
**Your repeater's RX/TX CC and TS. Set the Contact to 9998 echo test
*Tune to this contact, and open either brandmeister site (similar info)
*PTT and say hello while watching the website. You should hear/see yourself on 9998 echotest on this website

==Obvious steps==
*Check your channel
**RX and TX are often but not always offset
**TS is time slot, your repeater operator decides which timeslot it uses, so match that
**Color must match your repeater's color code
*Check your codeplug in Opengd77 CPS
**check your call sign is there
*Unplug the programming cable
**it wont output audio with it in

Raspberry Pi 4 - Screen Blanking manually via command line 2023

2023-01-18T18:59:30Z

Ddxfish:

This is how to disable screen blanking on Raspberry Pi in 2023. This would go in a crontab or can be manually run via the command line. I wanted my rpi screen to power off at night, then be on all day. Most guides seemed confusing, and raspi-config didn't seem to actually do screen blanking for some reason. This was my solution.

* Tested on Raspberry Pi 4 (Jan 18, 2023)

==Disable and Enable Screen Blanking on RPi 4==

'''Enable screen blanking on rpi4 so screen will automatically sleep after a while'''
export DISPLAY=:0; xset +dpms; xset s blank; xset s off; xset dpms force on

'''Disable screen blanking on rpi 4 so screen is always on'''
export DISPLAY=:0;xset s noblank; xset s off; xset -dpms

===Description of xset screen blanking commands on raspberry pi===
* xset s noblank
** Sets the screen to not blank
* xset s off
** Sets the screensaver off (if applicable)
* xset -dpms
** Turns off Display Power Management (dpms won't trigger the screen to sleep)
* xset +dpms
** This forces Display Power Management to kick in and sleep the monitor after a while
* xset dpms force on
** (not sure) I think this is +dpms but also forces the monitor to turn on.

===Auto start===
This command does not persist reboots. To run on every boot, create a script and add it to your startup items in your GUI. Or add to crontab -e on startup. Or make a systemd startup script. rc.local may even work if you're lazy.

==Disable RPi screen blanking in console==
'''This section is for an older Pi, I haven't tested on Pi 4'''

If your screen goes black during command line after 30 minutes or so, you have screen blanking enabled most likely. If you want to turn it off:

Edit the file '''/etc/kbd/config'''
Change these lines:
BLANK_TIME=0
BLANK_DPMS=off
POWERDOWN_TIME=0

==Troubleshooting==
Allow 15 minutes with each setting to see if the screen goes/doesn't go blank in the way you want. There may be other things that blank your screen, like system settings in MATE or other DE's, so look there too.
* Disable screen blanking in raspi-config
* Disable screensaver app, and in settings uncheck DPMS
* Check system settings (MATE or Lubuntu power settings etc)
* export DISPLAY=:0 is only needed if you run it via crontab or SSH.

Raspberry Pi 4 - Screen Blanking manually via command line 2023

2023-01-18T18:51:11Z

Ddxfish:

This is how to disable screen blanking on Raspberry Pi in 2023. This would go in a crontab or can be manually run via the command line. I wanted my rpi screen to power off at night, then be on all day. Most guides seemed confusing, and raspi-config didn't seem to actually do screen blanking for some reason. This was my solution.

* Tested on Raspberry Pi 4 (Jan 18, 2023)

'''Enable screen blanking on rpi4 so screen will automatically sleep after a while'''
export DISPLAY=:0; xset +dpms; xset s blank; xset s off; xset dpms force on

'''Disable screen blanking on rpi 4 so screen is always on'''
export DISPLAY=:0;xset s noblank; xset s off; xset -dpms

==Description of xset screen blanking commands on raspberry pi==
* xset s noblank
** Sets the screen to not blank
* xset s off
** Sets the screensaver off (if applicable)
* xset -dpms
** Turns off Display Power Management (dpms won't trigger the screen to sleep)
* xset +dpms
** This forces Display Power Management to kick in and sleep the monitor after a while
* xset dpms force on
** (not sure) I think this is +dpms but also forces the monitor to turn on.

==Auto start==
This command does not persist reboots. To run on every boot, create a script and add it to your startup items in your GUI. Or add to crontab -e on startup. Or make a systemd startup script. rc.local may even work if you're lazy.

==Troubleshooting==
Allow 15 minutes with each setting to see if the screen goes/doesn't go blank in the way you want. There may be other things that blank your screen, like system settings in MATE or other DE's, so look there too.
* Disable screen blanking in raspi-config
* Disable screensaver app, and in settings uncheck DPMS
* Check system settings (MATE or Lubuntu power settings etc)
* export DISPLAY=:0 is only needed if you run it via crontab or SSH.

'''This is for an old Raspberry Pi. See our new documentation here: [[Raspberry Pi 4 - Screen Blanking manually via command line 2023]]'''

This is how to disable screen blanking on the Raspberry Pi running debian (raspbian) which will stop the screensaver (a blank screen) from starting during command line usage.

==Disable RPi screen blanking in console==
If your screen goes black during command line after 30 minutes or so, you have screen blanking enabled most likely. If you want to turn it off:

Edit the file '''/etc/kbd/config'''
Change these lines:
BLANK_TIME=0
BLANK_DPMS=off
POWERDOWN_TIME=0

==Disable screensaver and blanking RPi in Pixel Raspbian==
This will disable screen blanking and blacking etc while within X on the Pi. This is for Raspbian Pixel
*edit /etc/xdg/lxsession/LXDE-pi/autostart as root
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
*Add these lines if they do not already exist

*edit the file /etc/kbd/config
sudo nano /etc/kbd/config
*Locate: BLANK_TIME=30
**Change value to 0

Mycroft - Use light ring on Seeed Respeaker 4-mic for Raspberry Pi

2021-11-16T01:38:40Z

Ddxfish:

This is a Mycroft skill for Raspberry Pi users who have the ***"Seeed Respeaker 4-mic Array for Raspberry Pi"***. The Respeaker 4-mic has a ring of LED lights that Mycroft core does not control. This skill makes the Seeed "pixel ring" on the Respeaker activate various patterns of lights when Mycroft is listening, thinking, or speaking.

Mycroft blacklisted skills not working

2021-11-10T23:16:57Z

Ddxfish:

To blacklist skills, you have to edit your mycroft.conf file. I had trouble removing some of the default skills in Mycroft and it was simply finding the right names to add to the blacklisted skills section.

==Find skill name to blacklist==
Find the exact skill name using mycroft-cli-client. Use the Mycroft command:
: skills

==Blacklist a default Mycroft skill==
Backup your mycroft.conf! Put this in your skills section of the conf. Edit to your needs, this blocks everything. NOTE that final comma after the array.
"blacklisted_skills": ["fallback-query.mycroftai","fallback-unknown.mycroftai","fallback-wolfram-alpha.mycroftai","mycroft-alarm.mycroftai","mycroft-audio-record.mycroftai","mycroft-configuration.mycroftai","mycroft-date-time.mycroftai","mycroft-fallback-duck-duck-go.mycroftai","mycroft-hello-world.mycroftai","mycroft-installer.mycroftai","mycroft-ip.mycroftai","mycroft-joke.mycroftai","mycroft-naptime.mycroftai","mycroft-npr-news.mycroftai","mycroft-personal.mycroftai","mycroft-playback-control.mycroftai","mycroft-reminder.mycroftai","mycroft-singing.mycroftai","mycroft-speak.mycroftai","mycroft-spelling.mycroftai","mycroft-wiki.mycroftai","mycroft-support-helper.mycroftai","mycroft-timer.mycroftai","mycroft-volume.mycroftai","mycroft-weather.mycroftai","mycroft-version-checker.mycroftai"],

Here is a version that keeps a few critical skills and fallback + wolfram alpha. This is more practical than the line above.
"blacklisted_skills": ["fallback-unknown.mycroftai","mycroft-alarm.mycroftai","mycroft-fallback-duck-duck-go.mycroftai","mycroft-hello-world.mycroftai","mycroft-installer.mycroftai","mycroft-ip.mycroftai","mycroft-joke.mycroftai","mycroft-npr-news.mycroftai","mycroft-personal.mycroftai","mycroft-playback-control.mycroftai","mycroft-reminder.mycroftai","mycroft-singing.mycroftai","mycroft-speak.mycroftai","mycroft-spelling.mycroftai","mycroft-wiki.mycroftai","mycroft-support-helper.mycroftai","mycroft-timer.mycroftai","mycroft-volume.mycroftai","mycroft-weather.mycroftai"],

After you blacklist, you can remove anything you don't want, or everything at all. Default apps that aren't blacklisted will be reinstalled at next startup of mycroft. You can put this in rm-mycroft-defaults.sh and run it if you want to remove all default skills. Edit the list to your needs.
