Resistor Color Code Decoder: 10K, 220 Ohm, More

The humble resistor is the lowest cost component in our maker box, but it is also incredibly useful. Previously, we’ve shown how to use resistors in a project, but the focus of this guide is understanding the colored bands which wrap around the center of the resistor. These resistor color codes tell us exactly how many Ohms of current each unit handles.

How to Overclock a CPU

Contrary to innumerable reports of its demise, overclocking is not dead — not by a long shot. Yes, overclocking headroom for core frequencies has receded as the Intel vs AMD rivalry has intensified and the chipmakers focus on squeezing out every ounce of performance, particularly in the highest-end flagship processors. However, Intel's Alder Lake chips represent a return of generous overclocking headroom, helping the chips take key spots on our list of best CPUs for gaming. AMD's latest chips don't have as much headroom for manual core frequency overclocking — the company's automated overclocking features are best for tuning — but like Intel, the company exposes a wealth of other tuning options for memory and fabrics, which can give you a nice bump in performance.
