Apparatus :RPI-4 4:GIG MEM REV 1.1…wd green ssd m-2
tall blue heat-sink heat sink with compound
and twin noctura 40mm x10mm fans 5.25 volt 4A plug pack
i cut the rpi-4 power supply lead off its now approx 500 mm long joining the plug pack supply
assorted threaded standoffs 3mm threads and what ever else i could find around to make it work…
with the tall blu heat sink and a single nocture fan it seems to be quite stable @2200Mhz@27 deg`s @ just with the gui open and a Firefox session with 4 threads 4 cores
i have ran it up to 64 threads before using stress-berry
but seems 2200 Mhz is the sweet spot i found
arm_freq=2200
over_voltage=6
gpu=750
==============================================================================
could the argon one m-2 case be fitted with a HDD activity led…
my usb to m-2 case has a activity led
I ran stress-berry for almost 30 mins @ 2330 via a terminal the gui was running
it crashed but the temp never got over 50 deg`s
so with the ice tower cooler and with my nocture fan on it
it made 20 degrees difference…getting a peltier next.see what i can get it up too…dont expect to get 2375 out of it though.
another handy package is neofetch apt install neofetch
a few other handy command line commands
apt -f install
will check your packages for defects and also dependencies if your having install problems
dpkg-reconfigure <package name>
will basically do a check on a specific file and refresh it or repair it…etc…
if you need help with a certain command type the command name then add this --help with a space between the name and help dpkg-reconfiure --help
or apt install --help
etc…etc.
man --help
man --dpkg
etc
brings up the help pages …also the web is handy for further examples…and syntax…etc…etc
did it again with the ice cooler tower and my nocture fan wound up to 8 volts and made it thorough 3 runs stresssberry default settings @2330Mhz…
upgraded to 21-04 from 20-10 today took approx 900Mb of down loads only approx 30 new packages
new kernel although it still reports the old kernel via cmdline ,though it did update the dtb etc…
METHOD:: u must use the development switch “-d” to upgrade to 21-04 ubuntu sudo do-release-upgrade -d
it will then take over and start doing the work…depending what packages you have installed it may request you to install update manager…manually…but most likely you will only have to answer a few questions along the way…
when it prompts you with a prompt to update the password directory structure i chose not to …therefore i answered “ok” then “no” it will pop up in a splash screen…there will be a few other prompts at the command line…simple answers…as long as your not over clocked above 2.2 gig it should all run smoothly…
in all honestly for an rev 1.1 board i think i have a “freak” cpu…seems like 2200 is it`s sweet spot with my talll blue heat sink i brought them from ameridroid
if any body is interested in getting them ,i do highly recommend them even without the fan they still cool better than the ice cooler sorry to say
but much better sink in my op and all i did was get a pair of side cutters to cut of the stand off eyelets…and a snug fit it does not touch the ram chip i think core should have something to put on top of the ram chip…not shure…have not looked into it …
after further testing i found that whatever you set the cpu and gpu and over voltage to is what the cpu will be running when the governor is set to performance…
under Ubuntu it has a cpu scaling monitor. app .i found this to only be a pull down governor control…
so for example if you have set the arm_freq=2000 and you have the governor set to performance then that is the max speed that the cpu will be running at.
you can govern it down but you cannot govern it higher than what you have set it to in the config.txt file but you can govern it down using the cpu scaling monitor.
.i have only just started to use Debian so i am not 100 % shure of its cpu control under the Debian gui…
These are some great benchmarking results! I’ve only managed to get mine to approximately 2.25GHz with an ice tower/peltier module hybrid.
This is reminding me of a Raspberry Pi Forum post I saw about a year back though when I first tried overclocking the Pi to it’s extremes. Someone reported getting 2.5GHz on the Pi when checking it with hardly any processes running, however when they ran a script designed to stress the CPU, the clock speed dropped to around 700MHz instead and found it was better to run it at a lower clock speed as it didn’t throttle and for lack of a better term “burn out”.
So it looks like the Pi can actually operate at those higher clock speeds without crashing, but as soon as they get stress-tested at all it doesn’t go well. It looks like you’re running some stress tests though, so I can officially say this is the fastest “working” clock speed I have seen on the Pi!
i dont think even a water cooler block hooked to a chilled beer coil covered in ice would be any colder than the peltier could do
the bottom sink i had a temp probe on and it was reading around 14 deg`s
my board blew up today… never mind il most likely buy an 8 gig model..dunno what happened exactly a power spike or surge in the mains or after i cannot tell i am going to try power it via the header pins but im not holding my breath
-omMMMMMy
