Re: Servers Power Consumption

Actually it depends.. I have seen a Raspberry 4B be powered with as low as 5.1V 1000mA. and a bit lesser if you underclock it. With that said. If you thinking about using more than one USB stick connected and if you intend to draw some CPU power as well from it you need at least 2,5A and beyond Im c...

Re: The Raspberry Pi 4 is fast – and hot!!!

Or get a Flirc case, which acts as a huge heatsink and keeps the Pi cool without a fan. If you are using a fan, the heatsinks probably aren't needed. One of my Pi4 computers is cooled by a fan alone, the other is in a Flirc. No throttling from either under any workload. Of the 2 solutions, the Flir...

The same. Set max_framebuffers to 1 in config.txt to reduce memory requirements for the framebuffers in legacy mode, and probably has some effect in FKMS mode as well.

To limit the amount of GPU memory in RPI4 B

In the older Raspberry PI you could limit the amount of memory the GPU used by the system by entering a line in config.txt
gpu_mem=16

But how do you do this with the new Raspberry PI 4 that have 2 HDMI-ports? I intend only to use one of the ports

So, Just to clarify things.. You can still use the old 5V 2,4A power supply, you just switch the cable from "USB-A -> micro-USB" to "USB-A ->USB-C"? There was no "5V 2,4A power supply" from RPF (that sounds like a phone charger). The official PSU was 5.1V/2.5A with a built-in micro USB cable. So th...
