Sorry Greg - I missed this.

I'm not so sure about that.  You can apparently show the current CPU
frequency with:

Code:

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

On my RPi4, running pCP (LMS & Squeezelite) I've never seen it show
anything but the currently set maximum.  So apparently there's a
difference, certainly in terms of heat generation, between an idling CPU
@1500MHz and one under load at the same frequency.  Or maybe that
command isn't doing what I think it is - that might explain why I never
saw it report a different frequency when I briefly played with the
governor settings in the tweaks menu.

Re: [slim] Pitastic



The amp got up to operating temperature, and I connected the fan at
14:16.  It seems to drop the temperature by ~5 degrees.  I'm guessing
it's no greater because it's mostly just moving warm air around inside
the amplifier, as kidstypike suggested.  The fan's not really big
enough, nor suitably ducted, to draw in fresh air.  I don't think it's
worth the effort.

That's true, and it has.  The baseplate has a grid of mounting holes:
[image:
http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/Enclosure/Base%20plate_480.jpg]

And the top plate has ventilation slots right above where I've mounted
the RPi:

http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/Enclosure/Top%20plate_480.jpg]

And the front and back plates don't seal against the baseplate.  So
plenty of ventilation.

I've now added the fan to the RPi4 in the amp, and I'm waiting for the
amp to warm up to see what effect the fan has.  This is more out of
curiosity than need, and I've left the fan's power connection accessible
so that I can disconnect it easily.

Agreed.  I needed a case for my spare 4B 1GB, so I ordered one of these
on the strength of your earlier post.  It arrived this morning.  I paid
£1 more and got the version with an SD card reader and a 3A power supply
:-)

I ran the same oggenc job that took my amplifier-mounted 4B 4GB up to 57
degrees.

[image:
http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/Oggenc%203.3V%20Fan_480.jpg]

Wired for 5V the fan is impressively quiet, but I wired it for 3.3V, and
it's effectively inaudible - I can only hear it if I put it close to my
ear.  Not that I need it, but I'm now toying with the idea of mounting
such a fan over my amplifier's 4B, since it's so completely quiet.

Thanks for documenting this.

I wonder, as the CPU is practically doing nothing, it is probably
throttled back to 600MHz most of the time. The periods of increased
speed are so short it is not captured by temperature sampling period.

Re: [slim] Pitastic

2019-08-10 Thread chill



I tried to find an underclocking speed that would make my 4B 4GB perform
similarly to my 3B+.  It's very difficult to find a test that eliminates
all the variables.  I settled on a single oggenc job on a 90-minute flac
file, as I figured that involved a bit of disk read and write, and a lot
of CPU activity.  I used the same hard disk on both machines, and I used
a USB2 socket on the 4B so as to match the 3B+.

On the 3B+ the task took 11m 07s.
On the 4B at the standard 1500MHz it took 4m 13s - quite an
improvement.
I had to underclock the 4B to 600MHz to get that time up to 10m 12s -
still 9% faster than the 3B+.  

The temperature conditions were far from equal, so the only thing I can
tell is that underclocking the 4B does lower the temperature, but only
by a couple of degrees.
The 3B+, sealed inside the official case without a heatsink or fan, got
up to 63 degrees during this task.
The 4B, mounted inside my amplifier enclosure (powered down, so at room
temperature) with a 40mm heatsink and no fan, got up to 57 degrees at
1500MHz, and 55 degrees at 600MHz.

So the surprising things for me were:
1) the 4B is very much faster than the 3B+ at this task with their
default clock speeds
2) the temperature savings by underclocking the 4B are minimal

So I shall be running my 4B at the default 1500MHz, and based on these
and earlier tests I'm happy that the conditions inside my amplifier are
fairly kind to the 4B.

I haven't - didn't even think to look there!

Plenty more there to investigate, thank you.  I think the 'Powersave'
option will do the same as I did when I set 600MHz, but it allows the
setting to be made without a reboot.  And there's also a separate
underclocking option, which evidently slows down a few other settings.

Actually, LMS isn't really much of a load.  So I ran some consecutive
oggenc jobs while LMS was rescanning.  Whereas this would have taken the
temperature into the low 70s, it now peaks at about 67 degrees.  So
maybe 5ish degrees improvement.  

Playback to 5 synced players still seems perfect at 600MHz.

In my case there's no real benefit in underclocking - the temperature
savings are minimal and I wasn't struggling with heat at the default
clock speed.  But maybe there'd be bigger gains for Pis in a tighter
space, or with a smaller heatsink.  Worth a try if you're up for some
testing.  To underclock, edit the config.txt file on the boot partition,
and uncomment the #arm_freq= line, e.g:

Code:

arm_freq=600

Re: [slim] Pitastic



Underclocking seems to make remarkably little difference in my setup -
perhaps 3 degrees under load.  I don't think my setup is completely
representative though, because my Pi lives inside my amplifier, where
the ambient temperature is higher than normal.  So I set it the task of
a clear and rescan on my library - when it's doing that I think the
temperature caused by the load on the CPU is less affected by the
ambient temperature.  But I do suspect the results will be slightly
different in other people's setups.

At the default 1500MHz

Underclocked to 1000MHz

Underclocked to 600MHZ
[image:
http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/Rescan%20at%20600MHz_480.jpg]

The scan times did take longer:
1500MHz: 6:04
1000MHz: 7:10
600MHz : 9:50

The interface still seems very responsive even at 600MHz.  My memory
isn't good enough to compare properly with how it was with my 3B+
though.  And I haven't tried it with music playback yet.  I think I'll
leave it at 600MHz for a while to see how well it performs.

I think that there should not really be so much resistance to using the
Pi4, cooling in enclosed spaces is somewhat of an issue but the benefit
of running a 4 may outweigh this. Its really just another thing to think
about, like do I have enough disk space.

Regarding the underclocking I think this is a good idea though finding
the balance may be time consuming but ultimatey usefull

Untill then a fan if probably the way to go as you and Paul- have found

All true but I submit it might depend on why you went to Tesco. You
might have gone in your Ferrari - which model have you got by the way -
in order to impress someone and not just for shopping. Mind you I
suppose youd go to Waitrose in a Ferrari so the point is academic.

All of the good things you mention about why the Pi4 is better than the
Pi3 are perfectly valid when considered in an appropriate context. I
applaud the fact they've decoupled the LAN from USB, and that it now has
USB3. (FWIW, I still think an onboard SATA controller would be the icing
on the cake, but we're still waiting for that).

But none of the Pi3's limitations you mention are significant in the
context of an LMS server. My LMS running on a Pi3 with library on an SSD
attached via USB2 has never, not once, ever, given me any trouble. It
supports 5 players no problem. You don't need gigabit ethernet and/or
USB3 speeds to stream the mickey-mouse data rates consumed by audio.

Using a more capable device when it's not justified, and suffering other
issues as a result, would be considered pretty daft in most walks of
life.
It's a bit like choosing to go to Tesco (Walmart for our US cousins) in
a Ferrari instead of a Ford - no advantage, and you end up burning more
fuel.

You say that Clive but all Pi variants before 4 feature a shared bus for
the USB and LAN interfaces which is known to be problematic. The Pi4
splits them and provides a full gigabit LAN and also includes USB3 ports
enabling users to attach a full USB3 drive which is much faster than
USB2. Apart from the overheating issue or non issue depending on how you
look at it a Pi4 + USB3 drive should be much quicker than a Pi3 + USB3
drive attached to a USB2 port.

It would seem that various people are trying out solutions to potential

I guess using a Pi4 then looking to fix any issues that arise is a case
of trying something for the fun of it,
but from a practical perspective, the solution is patently obvious:
don't use a Pi4.

The fit was much more convenient that I expected - it slid in between
the two ribbon cable sockets, touching both but without forcing them in
any way.

I think you're right - any serious continuous load will require active
cooling if the aim is to avoid throttling.  Fortunately for this
discussion, LMS+Squeezelite don't seem to represent a serious continuous
load. And I suspect that even if throttling does kick in, Squeezelite
would be unaffected and LMS only marginally, if at all.

For a bit of fun I logged the CPU temperature on the 4B in my amplifier
for a 24 hour period:

[image:
http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/RPi%20Board/pcp_cpu_temp_18JUL_640.jpg]

I can see:
- the gradual cooling of the amplifier after it was shut down at the end
of the previous day.
- a brief spike at 2am where the cron script runs to take a backup of
the SD card.
- a slight rise in temperature just after 10am.  I think this could be
when the sun hits the amplifier for a short period, and then as the sun
moves on the amplifier cools down again.
- a very clear warm up just before 6pm, when the amplifier was powered
up.  During the evening the amplifier variously played Squeezebox music
and TV sound, and there's no clear difference in temperature - it just
sits at around 65 degrees, which must be dominated by the ambient
temperature inside the amplifier.

My 40mm x 40mm x 11mm heatsink arrived today.  It just about fits
without having to be trimmed around the camera connector.  I used a
thermal pad to fix it to the CPU.

It seems to do the job.  I ran approx 20 minutes of oggenc jobs, and
simultaneously did a library 'clear and rescan'.  The temperature got up
to the low 70s, and then cooled back down to ~63 degrees.  The
'background' temperature inside my amplifier seems to be the dominant
factor.  I think this is simpler than trying to connect the CPU to my
amplifier chassis.

Re: [slim] Pitastic



Hi Jeff

No major change in the ambient, it may have increased a couple of
degrees since I started this morning.

I got the command from here

https://linuxhint.com/raspberry_pi_temperature_monitor/


Just checked again


Code:

pi@raspberrypi:~ $ vcgencmd measure_temp
  temp=54.0'C
  pi@raspberrypi:~ $ vcgencmd measure_temp | egrep -o '[0-9]*\.[0-9]*'
  56.0
  pi@raspberrypi:~ $
  



I 'found a little tutorial'
(https://www.cyberciti.biz/faq/linux-find-out-raspberry-pi-gpu-and-arm-cpu-temperature-command/)
and now have a bash script :)




Code:

pi@raspberrypi:~ $ ./my-pi-temp.sh
  Tue 16 Jul 16:49:24 BST 2019 @ raspberrypi
  ---
  GPU => temp=54.0'C
  CPU => 55'C
  




The area where the pi is can get fairly warm in the morning if the sun
is up, I'll just monitor the readings for a a day or so.

Has the ambient temperature changed while the measurement is being made
?

Do not forget that heatsink "effeciency" is above ambient IE if ambient
goes down 10 C so will the chip temp all things being equal.

That seems quite effective.  Will be interesting to see if it can hold
55 degrees under load.  Remind me - is your 4B in any sort of case? 

I've ordered a larger heatsink (40mm x 40mm x 11mm), just to see if the
extra side length is enough to make any difference.  It'll need a small
adjustment to fit around the camera connector, but if it works to
dissipate more heat energy (rather than just storing more) it'll be
simpler to use than my Heath-Robinson thermal link to the amplifier
chassis.

In the meantime I wrote my first ever Python script (yay!), to plot a
longer term CPU temperature log.

I assembled fan, header and case and powered up.

The fan began to spin and was just audible at about half a metre in a
quite room (faint noise, I would call it).

Started to play Music and ran a temerature check, got 42C. Played a ry

Swapped the sd card for a pCP install and started fip radio, temp given

Seems to work.

Pimoroni offer a script for raspbian which allows the fan to run
automatically to a preset temerature.

Hmm . . . I hope they come up with something workable, the Pi4 gets

carrier plate is easily filed to fit around the ethernet port. The
converter board wasn't used (doesn't fit), without the back plate fitted
the power USB (C) can be plugged directly into the Pi.

With the foil wedged so that it's making good contact with the enclosure
the performance is a couple of degrees worse than the 'free air'
example, but I think a few more folds of foil, some thermal compound,
and the 10mm aluminium front panel should all help to claw a bit back. 
I'm quite happy that it'll stay comfortably cool in normal operation.

My improvised thermal bridge - a few folds of aluminium foil wedged
between the fins of the small heatsink.  The foil doesn't grip very
well, so it's held in place with clear tape, but if I go ahead with this
then a bit of thermal paste should do the job:
[image:

Not yet bridged to the chassis heatsink, just flapping around in free
air:
[image:

Surprisingly it's knocked another 4-5 degrees off.  Here's a plot of
temperature from a 4 minute 'oggenc'.  Previously this took the
temperature into the low 70s.  Here it seems to have levelled off at 63
degrees before the oggenc process finished and it started to cool down
again immediately.

Throttling I guess, or just a warning, it was present for the whole of
the build.

Apparently it also appeared in Jessie.

It was the first time I had seen it as normally I do the build from my
Windows Desktop with no monior on the pi.

Apparently switching of the 4k setting and some other tweaks help to
reduce the heat (also running properly headless, to which I may
return...we'll see..sigh).

Presumably it was throttling at that stage, or was it just a quick
temperature spike?

I keep reading that a heatsink or fan is not needed for the safety of
the RPi, because the throttling is the failsafe. My impression is that
pCP running just LMS and Squeezelite isn't going to load the 4B enough
to cause throttling. But if something else causes the temperature to
spike and cause throttling, my guess is that that wouldn't have very
much effect on LMS, given that it isn't a heavy load.

I implemented the longer brass stand-offs to create a bit of space
around the CPU. I went for three 11mm lengths rather than 4 as in my
earlier photo.

[image:
http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/RPi%20Board/Long%20brass%20stand-offs%203_640.jpg]

This has dropped the temperature by 2-3 degrees. The key seems to be
the extra airflow. My small heatsink is arranged so that the fins are
vertical, so that air flows between the fins. The ribbon cable still
blocks the airflow a bit, but it's improved with the longer stand-offs.
And hopefully when those stand-offs connect to a big 10mm aluminium
front panel that will help a bit too.

The extra space would allow me to fit a fan or a bigger heatsink. A
bigger heatsink provides extra thermal mass, so can absorb more heat
energy and smooth out short spikes in temperature. But unless it also
benefits from extra airflow then it won't necessarily do much to control
temperature in the longer term - once it heats up the benefit is lost
unless it can also be cooled. So my aim is to search for a heatsink
that has a greater area than the CPU area, i.e. so that it presents a
wider profile to the rising airflow and benefits from more of that
airflow. The extra space also allows me to consider some kind of direct
thermal connection to the amplifier chassis. I'm going to experiment
with some folded-over aluminium foil to act as a thermal bridge.

Yesterday I imaged a new Raspbian Buster on my rpi4B (4gb). There is an
updated image on the raspberry site.

I ran the updates and install a sceensaver and PiShrink, but kept the
install as standard.

Right now I'm building a librespot Spotify-Connect client.

There is a neat little thermometer on the rpi desktop.

I ran 


Code:

sudo vcgencmd measure_temp



and got 82.0 C :rolleyes:

They seem to have broken compatability with all other Pi's anyway I
don't think one connector is in the same place.

I suspect you're right - there'll be more of that type of solution in no
time.  I think I'll work on making space for such a solution.  I'm sure
those fans are quiet, but it would be nice to keep it passive, given
that it's an amplifier.  I suspect that just making a bit of space to
breathe will be enough in my situation, and if not then a bigger
heatsink or a thermal connection to my enclosure will be plenty.

Here's a quick mock-up:

The sharp-eyed among you will spot that that's not a 4B - that's because
I haven't yet drilled out the mounting holes to 3mm in my spare 'BNIB'
1GB 4B. And the ribbon connectors aren't clamped down (no point wasting
them), but as a proof of concept it'll do.  Unfortunately, when there's
a ribbon connector on the pins there isn't room for stand-offs on the
two adjacent mounting holes, but the two on the opposite edge of the
board seem to be rigid enough.

Re: [slim] Pitastic



That's interesting if the board is part of the thermal design.  If the
heat is intended to reach the mounting holes, then brass stand-offs
should help to pull that heat away.  Another option is to use longer
stand-offs and make the 'hat' connection via a short ribbon cable. 
That'll create a bit more space around the CPU.  Yes, it would have been
good to have the CPU on the underside (for my installation certainly),
but I suspect they were conscious that this could affect compatibility
with a lot of earlier installations/cases/fans etc.

Its a pity that Raspberry did not flip the processor to the "underside"
of the board, then you could have good cooling AND a HAT !

Re: [slim] Pitastic

I've been running the pCP6 beta on a 4GB 4B inside my amplifier
enclosure. Some first impressions on the heat issues:

Running LMS and Squeezelite seem to provide only a very light load to
the 4B. CPU temperature seems to be dominated by the ambient
temperature and limited airflow inside my amplifier enclosure. So with
the amplifier powered up and playing music from Squeezelite, the CPU
sits in the mid- to high-60s. I can easily get it into the low 70s by
doing something more demanding, like transcoding a FLAC album with
oggenc, but for the majority of the time when it's just being a server
and a player the temperature seems under control.

I realise this is not an ideal environment for a device that may be
marginal on heat, and I may end up swapping the 3B+ back in, but the
extra responsiveness of the server, quicker library scans, and even the
faster reboots are all nice to have. I suppose I don't really need the
server to be running on this device, so I could even put an older Pi in
there and just run Squeezelite on it, and run LMS on the 4B externally,
but my target was always to have an all-in-one integrated amp.

As an aside, the amplifier enclosure is incredibly efficient at cooling.
I'm using a 'Dissipante' enclosure, which has sides that are giant
aluminium 'wave' profile heatsinks. I have my UcD400OEM modules mounted
directly to these heatsinks, and even when pumping out the volume the
heatsinks are never more than vaguely warm to the touch.

Access time is much more relevant for scanning performance than
throughput, and USB3 won't help with that.
However, the Pi4 supports 'UASP'
(https://en.wikipedia.org/wiki/USB_Attached_SCSI), which may explain the
small improvement.

Interesting case, didn't know about that one. I have a Rock64 in an
aluminium housing that uses the case as a heatsink, a little extruded
part of the case makes contact with the cpu and memory (through heat
conducting foil). It really helps to keep the temps down. Would the PI4
need anything like that (or benefit from it)? The Lincoln Binn casing
looks like it could do something like that, with the internal plate.
Performance and heat production still go togeteher, even on a 'simple'

Some more numbers for comparison.

My RPi 4 4GB arrived yesterday, so I've had a play with it this evening.
I've done a direct comparison against a 3B+.  I installed stretch-lite
on the 3B+ and buster-lite on the 4.  I did a bare minimum install of
LMS 7.9.2, with only the default plugins.  I used a Sandisk SSD with a
USB3 interface adapter. 

With the 3B+, a 'clear and rescan' took 6 minutes 30 seconds:

On the 4, with the SSD connected to one of the USB2 sockets, this came
down to 4:09*:

*I'm a bit puzzled by the 'Find updated coverart files' step in the RPi4
USB2 case - I though that was the MAI plugin, but that's definitely not
loaded.

I very rarely do a full clear & rescan - usually I just scan for changes
when I add new music to the server.

But FYI, I just fired one off:

Tracks: 14190
Albums: 1306
Playing Time: 1112:24:19
Clear+rescan time: 05:57

This is on a stock RPi 3 model B+ running piCorePlayer with the library
on a WD Blue SSD attached via USB.

(Now waiting in trepidation for my wife to complain that the "New Music"
list has been trashed :-)

Thanks for bringing OKdo to my attention. I never saw an announcement
from Radiospares (as I still think of them) concerning the launch.

@mherger

Actually running more Plugins on the pi.

I ran the scan on the pi before installing any Plugins

I have just a "clear and rescan" on the fully loaded pi

OKdo (a sub branch of RS)

RS say they will have stock later in July, I think. 

CPC, RS (and OKdo) seem to have better prices :p
