Seems you can get another 0.47ghz out of it !

How to overclock Raspberry Pi 4 — The MagPi magazine

 

I've just found out that the pi kernel can run in either 32 bit or 64 bit mode. It seems that simply uploading the 64 bit OS is not enough to max out the pi speed. By default it runs in 32 bit mode - perhaps this is for compatibility.

I wish they'd publish an official 64 bit image.

Can also recommend a piece of software called 'Commander Pi'.

 

Not something I have looked at until now, but there is some web suggestion a full ( not beta) 64 bit OS may be come with the Pi 5, whenever that happens ?

Would you be able to get much of a practical speed increase with a 64 bit OS, partic as most of your programs are still in and run as 32 bit code ?

What about the new Pi 400 ? seems that runs at 1.8ghz vs the Pi4 B at 1.5ghz, though expect thats a bit harder to modify and cool easily ?

 

I heard that the Pi 400 can be well over clocked - but I'm put off by the power, video and mouse leads being connected to the keyboard - and the naff keyboard itself. I much prefer wireless kit.

I did flirt with Ubuntu 64 on the pi - but it has time limited support - which put me off.

In terms of cooling - my pi runs at 2.1 and only has a fan. The fan is connected to the higher voltage gpio pin - but it doesn't make much noice and the pi has never throttled back.

I'm off piste with this pi - running a beta os off the usb 3 - overclocked and enabled 64 bit kernal. It works great as a desk top - but I can't update/upgrade the software as it may bugger up the install.

I reckon the next pi iteration will have memory slots - big no no at the moment is you're stuck with the integrated ram that you buy with the pi.

 

I've moved from Raspberry Pi OS to Ubuntu Mate. Ubuntu Mate is a true 64 bit OS for the pi - if I change to 32 bit mode the pi won't boot. 64 bit Raspberry Pi OS was just taking too long to move out of beta stage.

Even running in permanent turbo mode at 2.1 Ghz - Mate is both stable and fast - I've been converted.

 

I was wrong. If you increase the voltage to the cpu - it will run faster. Now running at 2.3ghz - so far looks to be stable - but the temperature has increased to 47oC - I can live with that.

There is talk of a Raspberry Pi 5 - I'm starting to drool already..

 

Seems no real info on the Pi5 release date, could be next year ..? though sounds like it may just be a minor update to the Pi4 rather than any major changes.

47c still well cool, there is always liquid cooled heatsinks if you get too hot.

Whats it like speed wise, from an everyday view, when running things like Office suites downloads and watching videos online ?

Seems W11 may be more restrictive / controlling when it arrives, so Linux may still have a place.

 

It's fine as an every day desk top. I've also increased the GPU speed by 50% and allocated more memory to graphics.

Moving to the 64 bit version of Ubuntu Mate was a game changer - it's 64 bit all the way through and has been rock solid. I also like that there are regular updates - all free. Raspberry PiOS are still in beta stage for their 64 bit OS. Windows is now a distant memory - I'm not going back to it.

If they add a ssd memory slot to the next iteration - that will make it even better.

I had my 2nd AZ jab today - hurrah .

 

Tempting us to try Linux again, for about the fifth time
The difference now is that we have a separate control box for the security cameras, before it was via a 4 channel PCI card on the mobo, but for Windows only, so could not ditch windows fully.

Might rig up a separate SSD alongside the Windows SSD but with a switch in their power lines so we can select which system we want.
Know we can dual boot, but that always seemed to lead to problems, used Mint Cinnamon then.

Don't think its worth using the basic old Pi3b, unless you suggest otherwise ?

Only got your second vaccine now, 3 months since we had ours, thought you were a bit older "Gentleman of leisure." - Retired , or is that Retired but not OAP ?

Hopefully these jabs will last a long time, though for us oldies seems they might give us a third covid booster jab in autumn along with the usual flu jab, ouch.

 

I did have a Pi 3 - yes it is a usable basic desktop - it can be overclocked as well.

There are indications that our immunity will last years rather than months - as it does for other corona virus flavours.

Packed in work in 2017 - I'll be getting my state pension in 2032. That is assuming I make it that long .

I do draw a works pension - so I am a pensioner .

Scrungee beat me - he retired earlier than I did .

 

That applies to many of us !!

Keeping the brain cells going is probably key, seems like the Pi is your techie interest.

Been looking at 3D printing but think it might be a step too far ! - probably stick with the Arduino projects, have tried some things with the Pi and Python, but each has their own pros and cons.

 

Got out our old RS Pi 3B + 1gb ram, which runs Raspian ok, usable though quiet slow even compared to a very old laptop with Linux.

Thought we would try Ubuntu Mate on it, and followed Ubuntu Mates Site instruction.
Raspberry Pi | Ubuntu MATE
Seems there are two versions, which according to them both ARMhf and ARM64 v20.04 should work, though HF probabalby better for 1G devices.

Loaded up ARMhf but when booting it just gave several lines of CPU and memory errors/ not found, then stopped.
Ran the AMR64 and it did start and went into the setup, but after a slow 20-30 mins came to a stop.
Rebooted and the desktop did load very, very slowly, but unable to activate anything, the green cpu light buzzing away

Not sure whats gone wrong if the official site nstructions do not work ?

 

Have a go at over clocking it - be interested to see how fast you can get it to go.

The amount of RAM stifles performace - but over clocked I found that it was ok for surfing t-net etc.

 

Hi,

Assume you mean overclocking using the Raspbian OS ?

Any suggestions where we have gone wrong trying to load Mate ?
The online tutorials, including Ubuntu Mates own seem simple enough, but neither 32 or 64 bit would work ? - tried a few times with both - or just stick with Raspbian ?

Might have looked at getting a Pi4 , but if Pi5 just around the corner ??

 

I used the 32 bit Raspbian OS - although the pi3 has a 64 bit processor it doesn't have enough ram to make it worthwhile building a 64 bit OS. So I believe all pi3 OS's are 32 bit.

In both Raspbian and Ubuntu Mate - the method for overclocking is the same - you amend the config.txt file - which is under /boot in Raspian and /boot/firmware in Mate.

I'd stick with the 32 bit version for the pi3 - then use whatever prog you use to create a bootable OS sd card. I tried a lot of different flavours of Linux using the Raspberry Pi imager software - which you can get for free from here :

AFAIK a Pi5 is just speculation at the moment - based upon the timing of the issue of previous models. I wouldn't wait - pi's are so cheap they're virtually throw away hardware. Most of the peripherals you purchase for a Pi4 will more than likely also work with the Pi5 - unless there is a massive step change in technology.
