2-4 hours of work sounds a bit optimistic.

Perhaps your time would be better spent in different, more constructive ways than making silly remarks on a forum.
If you have time to wait for 64bit Raspbian, you have time to try another distro that suits your needs. You don't lose anything.
He/she's saying it will take *a user*, you/me/someone else, 2 to 4 hours to install a Raspbian 10 64 bit and set it up to work as their current Raspbian 10 32 bit setup is working.

I can't see the problem with that claim.
Yes writing an new image in Etcher and just running through the setup will be half an hour or quicker (so under optimistic). But then getting chrome, links, programs etc will take longer form many is probably correct.

Setting up full servers and things may take longer.

Ignoring the switch over for distro's such as LibreElec/retropie/etc if it benefits them.


Phil, LibreElec is build on 32 bit Raspbian, they get advanced time to OSs and headware (they had the Pi4 half a year before us) and they do work together.

It just an image on an SD card, but built around a media setup. So if you get a bit of bored time, give it a go.

There are plenty of thing that have turned 64but only, we just have to use the older version.
For me, that good enough at the moment.

The Pi Zero is their stumbling block, they still actively sell them.
(Still the original B+/A+ have an obsolescence date of 2026)

I still think they could drop the Desktop on them and move to a lite release only.
(It's painful using the desktop on them now anyway).
But they have a plan, a few people, and a goal for what they want to do.

I look forward to the release of the 64-bit version of Raspbian, which should improve the CPU's computational performance, bring 4K video support, and compatibility with 64-bit softs like Opera, Google Chrome, etc.
4k already supported in libreElec using the HW HEVC decoder, will also be available on Raspbian in the future. Chromium already supported in 32bit version.
I dont use libreElec but Raspbian. I am an NT systems administrator, Debian is my Linux reference system and I will not reinstall x OS for testing, I have time to waste with it ... I prefer to wait for the availability of Raspbian 64 Bit.

Chromium and Opera, which is a derivative, are only available in 64-bit and not 32-bit versions ... Some other softwares must also pose this downward compatibility problem.

I read that from RPi 3 the CPU is 64 bits, it is a pity that Raspbian 10 is only 32 bits for the moment. This is only useful to users of very old generation RPi 2 & 1. For this older RPi Debian 9 is officially supported until June 2022 ... It is a bad strategic choice on your part in my opinion to have dont offers Raspbian 10 64 Bits right now.We will have to waste time to reinstall everything in a few weeks.If you consider the number of users multiplied by 2 to 4 hours of work, this represents a significant loss of human potential ... and this does not give a serious reputation for you ;(

If you want advice in the future, to ask us what we would like to see in the form of e-mail surveys, I am open to support you.

Best regards.
32bit Raspbian works fine on every single Pi out there - which is 27Million of them. The computation difference between it and any 64bit OS is marginal. Chromium works fine on the Pi in 32bits so your statement it's only available in 64bits is wrong - it's our default browser and has a lot of optimisation work. There are some apps that only work in 64, but they are few and far between.

64bit Raspbian will not be out "in a few weeks", it's many months away. We are not even working on it right now, because we know that the current version works fine, and the performance benefits are minimal. It will be done though, it's a clear development path. Likely initially a 32bit userland with a 64 kernel. 64 bit userland is rather awkward due to problems interfacing with the 32bit Videocore.

I think we are ok for advice, thanks.

"2 - 4 hours work". Sorry, but this idiotic. Obviously you don't know what you are talking about.
I certainly know what I'm talking about but hey, you have the right to have a point of view on the subject...

I leave you to ponder your need to question the opinion of others.

There are times when the ego makes us blind and prevents us from respecting others...you still have to be a very young person to try to impose yourself thus.

A troll that has not done the research.
32 and 64 bit Chromium runs on Pi's now.

64bit OS's are in progress and who says it has to be done by RPF anyway?
They make lots of hardware and one OS.
For their mission one OS is all that is needed.

We have choices of other OS's and can even make our own if we want.
If someone does not like Raspbian they can make their own OS.
It is a bad strategic choice on your part in my opinion ...
More a pragmatic decision for the current situation? That's just my opinion.
RPF have said they will do a 64 bit OS eventually, but they have lots of other things to do in the meantime.
As more Pi stuff gets mainstreamed the more choices we will have in the future.

Most of those working on 64bit Pi OS's are doing it outside hours.
That takes longer.
this represents a significant loss of human potential
Well just wait then, no need to buy Pi's either, save them for us.
Someone who won't wait for free software on cheap hardware?
2-4 hours to swap each uSD, hmm sounds like a public or Gov institution ?

1040 kn/s stable for days running stockfish with fan
( presumably a bad compile , obtained with apt-get install stockfish)

without fan it goes down to 740kn/s after 1-2 hours.

I'm waiting for Android, so I can run the optimized
C-Fish compiles in Droidfish, which gave 2500 kn/.s
on the odroid-n2

The pi3b starts at 540 kn/s , going down to 400kn/s without fan

I have no case to fasten the fan, so I put it on 4 small polystyrole feet,
(over the heatsink)
maybe a rubberband had been easier ?!

just one of these $1.50 fans at ebay
the weak performance as compared to the Odroid could be due to the 32-bit
vs. 64 bit executable ?!

one of these 35g Aluminum heatsinks
https://www.ebay.de/itm/Silver-Tone-Alu ... 2994830462?
was sufficient to prevent throttling on the pi 4b running stockfish , although it still displayed the
flashing thermometer. So I did put 3 over each other and the thermometer disappeared
and they all became hot. You could just hold the 3d and touch the 2nd but not hold
the 2nd for more than 10sec .
So it's easy and cheap and works but makes the pi big and it won't fit into the case.
And I also tried a little fan , it's also cheap and silent and smaller and more effective.
I think, these one-board computers should have a fan by default.
http://magictour.free.fr/pi4bcool.jpg
------------edit -----------------
the flashing thermometer reappeared despite the 3 heatsinks. But only quickly,
every couple of seconds. I don't know how/whether to get the CPU-temperature in degrees directly

I have received my armor-case from geekworm and is working very good.
I am using a thermal pad Thermal Grizzly Minus Pad 8 (1mm thick) you can put on CPU, RAM and Chip-USB.
Here is a good web page about thermal-pads...

https://graphicscardhub.com/best-thermal-pad/

https://es.aliexpress.com/item/40000019 ... 63c0O2dQ3U

Idle Raspbian is 42C
Youtube 1080P and DVB-TV at same time is 52C
1 hour of cpuburn-a53 is 64C.

Onboard wifi 5Ghz is ok.
Onboard wifi 2.4Ghz is affected by USB-3 interference but is not a problem with armor-case this happens too on any other case, is related USB-3 interference with wifi 2.4 on any PC not only on raspberrypi.
If you want good signal wifi onboard 2.4 do not use USB-3 and use only SD boot and USB-2 or use an extensor and external wifi dongle.
USB-3 is very close to the antenna in rpi4b because rpi is very small form factor.

The armor-case is nice and tiny.
If you want a totally silent case this is a very good option.
Very happy with the purchase.
Thats nice. However, I need to put a Hifi-HAT, and this heat sinks blocks the screw holes I need to attach the HAT.

Does anyone know of a HAT-compatible cooling solution for the pi 4? Mine is around 50-60° in idle, and 80° when compiling (with no cooling but also no case, that is).

Maybe I would have to 3D print a custom case, it does not seem like there is existing solutions for a HAT + heatsink out there :/

From these temperature reports, I am beginning to wonder if my Pi 4 is frigid; not really.

I am running with 2.4 WIFI, driving a 27" monitor at 1920 x 1080. The board is encased in a Smraza case with 3 heat sinks and a fan and at idle, it doesn't get above 32 degrees C.

With a Fan and sufficient ventilation, your temperatures look fine. The issue is with a) Passive cooling temperatures b) Using the official Pi 4 case which doesn't have any means of providing airflow.

Hi all,

Following a successful trial with our alpha testers, we are releasing a new firmware build for the USB3 host adapter that should save about 300mW and help the Pi4 to run cooler, which in turn improves performance in compute-intensive tasks.

Download the archive from here: https://drive.google.com/file/d/1PXwrnh ... sp=sharing
With the zip file on the Pi:

Code: Select all

$ unzip vl805_update_0137a8.zip
$ chmod a+x vl805
$ sudo ./vl805 -w vl805_fw_0137a8.bin
$ sudo reboot
The zip file includes the current shipping firmware (013701) in case you want to revert:

Code: Select all

$ sudo ./vl805 -w vl805_fw_013701.bin
$ sudo reboot
By the way, if you run "sudo ./vl805" with no parameters it displays the version of the currently running firmware. Note that this may differ from what's in the EEPROM if you've just reprogrammed it but not rebooted.
I had problems using this firmware with a ZWO ASI 120MM-S camera.
OS is an alpha version of StellarMate – (Ubuntu 18.04.3, 4.19.63-v7l+)

Reverting to vl805_fw_013701 fixed the stability problems, although the following are still showing up in syslog:

After adding a USB fan which is on top/next to my Pi 4, it's a lot cooler:

temp=36.0'C

I'll be buying the "fan shim" once I have the spare funds.

More related to the output from vcgencmd measure_temp than the actual values, but my older Pi's all report the temperature to one decimal place :-

Code: Select all

[email protected]:~ $ vcgencmd measure_temp
temp=40.6'C
Where as my p4 is whole numbers only :-

Code: Select all

[email protected]:~ $ vcgencmd measure_temp
temp=37.0'C
Any reason we don't get more granulatity on the Pi4? Its not a problem, I'm just curious

And yes I've got a fan shim on my p4 which is why its quite cool.

I have just been told off for sitting for too long at PC during family holiday when all I have done is tried to catch up on this thread.

Can someone post a summary - or link to a web page that is being maintained - that shows current status including effect on temperature and expected next steps for:

- firmware changes
- config.txt changes (reducing freq for example)
- official Pi case MkII (if planned)
- official case homemade mods
- variable speed fans (ideally temperature controlled)

Then that summary could be updated weekly with best of the latest wisdom until seen as no longer worth discussing.

Alternatively - if all posts in this thread that are not temperature related (e.g. 64 bit OS) or do not add to collective wisdom could be pushed to a different place then it would make it easier to catch up.

I remember there were some plans to reduce (idle) power consumption with software changes to the DRAM controller or the graphics driver. Are we going to see anything in this regard any time soon? And what happened to the VLI firmware update, are there any further updates coming out?

If you have any kind of case - even a half-open one - the Raspberry Pi 4 in default configuration throttles really hard and quick after it has warmed up. This isn't really acceptable.

Just set up my 4GB Pi4 from CanaKit with a 128GB SD, running Kodi on current Raspbian desktop (top reports Kodi drawing 60% CPU, load average: 1.02, 0.94, 0.90) rendering video to a 1920x1080 HDMI monitor from the onboard SD card. WiFi and Bluetooth are active, but mostly idle. Pi is mounted in case, vertically on the back of a wall mounted monitor - monitor doesn't generate much heat on its own, room is about 23-24C ambient, not too much airflow, PI is about 4cm away from the wall. With the lid on the case it was hot, I believe it shut itself down after about 10 minutes of playing video. Removed the case lid, now running 72-74C while rendering video. Have not installed the supplied heatsinks yet...

I don't minimize the issue, but 'any kind of case' isn't quite right (even ignoring the possibility of adding a fan). My Pi 4-4 is installed in a Flirc case, and the ambient temperature in my office is currently around 28 C. The Pi's CPU temperature stabilizes at just below 50 C when it is idling, and stays below 55 C doing routine things. Running stress with 16 CPU hogs gets it up to about 70 C, and even running cpuburn-a53 does not get it up to 80 C (after about 30 minutes it was at 76 C, and seemed to have almost levelled out) and/or provoke throttling.

Re: Raspberry Pi 4 temperature

Sat Aug 10, 2019 4:12 am

now I figured out how to measure CPU-temperature
https://praxistipps.chip.de/raspberry-p ... ehts_46615
vcgencmd measure_temp

the pi4b running stockfish with 4 threads gets to 82C after ~10min without any heatsink
and kn/s go down to 920kn/s (continues to fall , I once had ~740kn/s after 1 day) )
after an initial 1006 kn/s.

With one of the 40x40x20 mm heatsinks temperature is 74C (ambient=24C) and kn/s is stable at ~1002 kn/s

With two of the 40x40x20 mm heatsinks temperature is 72C (ambient=24C) and kn/s is stable at ~1005 kn/s

With three of the 40x40x20 mm heatsinks temperature is 68C (ambient=24C) and kn/s is stable at ~1005 kn/s

With three of the 40x40x20 heatsinks plus a 100x100x20 heatsink on top of that
temperature is 69C and 1006 kn/s , so that doesn't help anymore

With just one of the small pi-heatsinks temperature is 82C but kn/s still at >1000

I remember there were some plans to reduce (idle) power consumption with software changes to the DRAM controller or the graphics driver. Are we going to see anything in this regard any time soon? And what happened to the VLI firmware update, are there any further updates coming out?

If you have any kind of case - even a half-open one - the Raspberry Pi 4 in default configuration throttles really hard and quick after it has warmed up. This isn't really acceptable.
I don't minimize the issue, but 'any kind of case' isn't quite right (even ignoring the possibility of adding a fan). My Pi 4-4 is installed in a Flirc case, and the ambient temperature in my office is currently around 28 C. The Pi's CPU temperature stabilizes at just below 50 C when it is idling, and stays below 55 C doing routine things. Running stress with 16 CPU hogs gets it up to about 70 C, and even running cpuburn-a53 does not get it up to 80 C (after about 30 minutes it was at 76 C, and seemed to have almost levelled out) and/or provoke throttling.
The Flirc case is not a regular case: it's quite expensive and more like a case-sized passive heatsink than a regular case. It also interferes with WiFi and Bluetooth connectivity and you can't access most of the on-board I/O connectors. We don't need any more marketing for this case: we know it works, but we also know it isn't suitable for most users.

My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

I agree that this was misleading. What I was going for is that typical cases that even slightly reduces convection and airflow (so basically all standard cases, even half-open ones), you will have major issues with the Pi 4. It's a huge difference compared to the bare board sitting on the workbench.

Of course you can argue all day that intricate and expensive cooling solutions can solve the thermal issues, but this isn't what the Raspberry Pi was marketed to be used with. It was supposedly designed to be used without a heatsink inside a fully closed case. It would be great if software improvements would actually make that possible, but unfortunately there has been silence on that front for the last couple of weeks.
