Voltlog #266 – How To Check If Your Raspberry Pi 4 Is Throttling CPU

Welcome to a new Voltlog, today my raspberry pi 4 is again in the spotlight because I want to show you the different scenarios where the board could be throttling down the CPU frequency and how you can identify those. Because it might be a case where your raspberry pi is running slow on a particular task and you don’t know why because there is no built-in mechanism to let you know when the board is throttling down. There are logs which you can check but let’s be honest, few people actually check the logs for something like this.

Throttling of the cpu frequency occurs for good reasons, to protect the board or the cpu from overheating or to prevent any errors from occurring in the case of an under-voltage scenario which may lead to data loss or corruption. Luckily there is a way to check if your system is under one of these conditions, you can run this command on your raspberry pi.

Voltlog #264 – Passive Heatsink Cooling For The Raspberry Pi 4

Welcome to a new Voltlog, here is my raspberry pi 4 which I got a few months ago when they released it and if you have one you might have noticed it gets quite hot especially when it has to do some processing. This newer processor, will get hot quick and the board alone cannot cope with all of this heat so what does it do? Well when the CPU temperature reaches 80 degrees Celsius it will start throttling down the CPU as a way of protecting itself from overheating and this will result in a loss of performance.

The Raspberry Pi 4 has a 1.5GHz quad-core 64-bit Arm Cortex-A72 CPU, that’s roughly three times the performance of the raspberry pi 3 cpu. That inevitably generates more heat. In the original plastic case just sitting idle, connected to a network, doing pretty much nothing, the raspberry pi4 when compared to a raspberry pi3 runs about 12 degrees hotter.

Voltlog #199 – New Editing PC With AMD Ryzen 7 2700

Welcome to a new Voltlog, this one is probably the last one on 2018. I would like to start by thanking you for being here with me, accepting the mistakes I often make in my videos but let’s face it, having a completely correct story is no fun, there would be nothing to discuss at the end.

I finally managed to upgrade the Voltlog editing machine. I previously used a dell laptop which had an Intel i5-3340M, it had plenty of ram, an SSD but editing was quite slow, roughly 3 times the length of the output video.

So at the end of this year I decided to build a new editing machine, I immediately found out the best price/performance ratio is with the AMD Ryzen processors.

I had a budget of $700 and I am quite happy with what I got in the end for the money. I started with a Ryzen 2 2700 processor, this is an 8 core processor, 3.2GHz, pretty fast. Not as fast as the 2700x but I had a budget restriction so I settled for the 2700. For the motherboard I went with the MSI B450 Tomahawk, for ram memory I got a Micron 16GB DDR4 PC2400 stick, for storage I went with Samsung Evo 860 1TB SATA SSD and for power supply and case nothing fancy, just something that was available on my local distributor.

 

Voltlog #157 – Raspberry CryptoPI Designed For Mining Ethereum

In this video we’re taking a look at the new Raspberry CryptoPI, a single board computer designed specifically for mining Ethereum. It features 8GB of GDDR6 and a new Nvidia VOLTA GPU. Release date Q3 2018 at a cost of around $400 USD. Let’s hope there will be some units left for us because I am expecting whales to buy these in thousands qty.
