What to Do When Your Computer Only Fans Run After Booting?
When you power on your computer and only the fans are running, with no response from the monitor, it certainly indicates a hardware issue. The best approach is to use a process of elimination to identify the problem. Here’s how:
1. Press the Caps Lock key on the keyboard. If the light turns on, it indicates a fault with the graphics card, monitor, or other hardware.
2. If the keyboard
Overclocking Methods for Raspberry Pi 400
Overclocking the Raspberry Pi 400 is very easy to achieve. In terms of heat dissipation, the Raspberry Pi 400 is designed with a large passive heatsink, which is very useful. There is no need for additional active cooling to meet the heat dissipation needs of overclocking.
Although some users have configured the Raspberry Pi 400 to overclock to 2.2GHz, I believe that 2GHz is more stable.
Overclocking Settings
Here are the steps to configure overclocking on
Introduction to Mainstream Router CPUs on the Market
In the last issue, we introduced some mainstream router CPUs: 【Router Series】 Introduction to Mainstream Router CPUs 1
This issue will complete the remaining information, but they are mostly mid-to-high-end routers, so enjoy reading.
1: BCM4906/4908
These two chips are the true successors of the 470x series, adopting the ARMv8 A53 architecture, with a frequency of 1.8GHz. The main difference between the two chips is that one is dual-core and the other is quad-core. With the A53 architecture and 64-bit support, the clock
