Surprise! Unlike previous RPi models that I have experienced, Pi4 REQUIRES a new OS. (Product Description states “Complete compatibility with earlier Raspberry Pi products”) If one tries to use an existing NOOBs or SD card from an operational Pi0 or Pi3, this unit will fail to boot. Luckily a claim that the unit is defective (as it appeared) met with outstandingly swift replacement. When I got the replacement it did the same thing, prompting me to do proper diagnostics. A Google search for “pi4 fails to boot” brings several results. One of which is from PiHut so I followed it. They plainly state “Operating System - Only the latest operating system release will work on the new Raspberry Pi 4 (at time of writing NOOBS v3.1.1). This will also need to be a fresh install, not used with a previous model of Raspberry Pi” For casual observers, this OS’s name is Buster, not Stretch so even an update/upgrade cycle won’t do it. I reviewed the description of my purchase to see if I missed it and read existing questions and several reviews - no joy.
Secondly I have HDMI adapters for RPi0 – NOPE! The RPi4 uses micro-HDMI whereas the RPi0 uses mini-HDNI. (back to the store).
I’m retired. This is a hobby to occupy my time – mission accomplished!

Check your WiFi!!!!! Mine crashes after 1 week
Reviewed in the United States on January 20, 2020
I got excited and used this for a plex server build. Well, about after one week the server would crash. The WiFi would not work and the system would become laggy. I don’t want to believe that this was the nature of this item. On the bottom of the box it said made in China and it was an element 14 box. I’m not a fan of the element 14 brand as I could never overclock them like the RS component pi boards. For some reason the board I got I think had a defect. Once the week went by, the WiFi would never work again. It wouldn’t connect to 2.4ghz, or the 5ghz bands. I cleared all settings I could but nothing would work. Once I restarted the pi the WiFi wouldn’t even register until forcing some setting changes. Even at that, the next reboot would result in no internet. I have another pi 4 that works beautifully but this one is falling on its face. I have a 3b+ plex server and it works beautifully!!! It doesn’t care what you do to it. The pi 4 plex server. Finicky as hell!!! Check your pi as mine had a WiFi defect.Order from canakit to be sure you’re getting quality parts. I’m getting a replacement one however if it says made in China on the box again then I am immediately returning it. I won’t accept the China versions of the pi 4 after this! I feel like I’m going crazy because of how inconsistent it’s acting. I hate second guessing myself!

Hier mal eine kleine Anleitung:
1. Die beiden Lüfter des Kühlkörpers durch kleine Unterlegscheiben an den acht Schrauben um 1 mm anheben. Der Luftstrom verbessert sich merklich.
2. Die vier Schrauben, die Ober- und Unterseite des Kühlers zusammenhalten, reichlich mit Wärmeleitpaste einschmieren und erst dann reindrehen. Besserer Wärmeaustausch zwischen den beiden Kühlerhälften.
3. Zwei 4 mm dicke Wärmeleitpads zwischen die Platine und der unteren Kühlerhälfte, und zwar da, wo auf der Oberseite die CPU und die Spannungsregelung sitzt. So ist die Kühlerunterseite wärmetechnisch voll eingebunden, da sie sonst keinen Kontakt zum Raspi 4 hat, außer mit den Montageschrauben.
4. Mit "sudo nano /boot/config.txt" die passenden OC-Einstellungen eintragen.
Ich habe den Raspi 4 bei einer Raumtemeratur von 27 Grad (der letzter Sonnabend war wirklich sommerlich) stundenlang im Stress gehabt. Mehr als 48 Grad auf der CPU kamen mit dieser Lösung nicht zustande, und das bei 2 GHz. Als Netzteil nutze ich eines von einem Huawei Mediapad M5, liefert 5 Ampere.
