Double the memory of your Pi-Top

A recent contribution on You Tube demonstrates how to double the memory and the swap space on your favourite Pi-Top, together with a couple of useful other report and utility routines they turn any RPi or Pi-Top into a useful piece of kit? I will share this link with anybody who asks. I was pleasantly surprised as I only needed to copy and paste from the article to my terminal to install and run and to add a few lines of text to a configuration file to install these useful ideas at reboot. A simple and well informed demonstration.

I'll bite. YT URL?  Thx.

Hi Steve, first just log on to You Tube, do you have an account? Search for Novaspirit Tech

This guy is amazing, he's got so much on the RPi you'll be busy for weeks!

Look under his Videos tab and just look down the list as the list grows from the top! You'll see "Double your RAM" for the Raspberry Pi.

It truly works but unless I've done something wrong, my memory slowly fills up with something. So I've got a bit more research to do. I reset my RPi about x2-3 times per day to keep the memory in check. It dos not take too long to restart a RPI with sudo reboot. The Amazon echo looks really cool to have around the house especially if the speakers etc are hidden from view!

Good Luck!

Once you subscribe to his account, its much quicker and easier to keep referring to the new stuff etc. But you need to create an account with Google (1 account 1 sign in) to get the best out of all of this. I thought Raspbian came with Chrome already installed so it couldn't be easier.

I hope this helps?

URL: "Increasing Ram on your Raspberry Pi with ZRAM"

Actually, the title is misleading; your RAM is not increased; it's compressed.  That means that when memory is stored, it's compressed; when accessed, it must be decompressed.  More Linux kernel overhead.  The technique is to make use of a special kernel object called zram which is available in any modern Linux distro.  Most Linux users avoid this and simply buy more physical RAM (a total of 2GB or 3GB is probably sufficient for most Linux desk/lap-tops).

RPi's biggest shortcoming: being limited to 1GB RAM.  If you launch Chrome with one open tab it costs you 6 memory-hungry threads.  Now, launch LibreOffice.  Fun, eh? 

On one of my RPi stand-alone systems, I have gotten rid of the MicroSD (sluggish and poor longevity storage) in favor of an external USB disk for booting and post-boot operations.  This makes up somewhat for the lack of RAM in terms of performance.  Unfortunately, this is awkward for the pi-top as one would prefer placing an mSATA or SSD inside the case (E.g. on the rail).  Still trying to find an mSATA/SSD solution for the pi-top.
