While the AMD Ryzen 1000 series of CPUs were well-received for their impressive performance and value for money, they are not without their faults. Here is a list of some of the bad things about the Ryzen 1000 series CPUs:

1. Overclocking limitations: Although the Ryzen 1000 series CPUs have a high potential for overclocking, the overclocking headroom is limited compared to other CPUs in the market. This can be frustrating for users who are looking to get the most out of their CPUs.
2. Limited support for older motherboards: The Ryzen 1000 series CPUs use the AM4 socket, which is not compatible with older motherboards. This means that users who want to upgrade their CPU will also have to upgrade their motherboard.
3. Poor stock cooler: The stock cooler that comes with the Ryzen 7 1700 is not up to par with the performance of the CPU. Users who want to overclock their CPU will need to purchase a separate, high-quality cooler.
4. High power consumption: Compared to other CPUs in its class, the Ryzen 1000 series CPUs have a high power consumption, which can be a problem for users who are looking to build a power-efficient system.
5. Single-thread performance: Although the Ryzen 1000 series CPUs have a high core count, their single-thread performance is not as good as some other CPUs in the market. This can be a problem for users who use applications that are not optimized for multi-threaded performance.

In conclusion, while the AMD Ryzen 1000 series of CPUs offer impressive performance and value for money, they are not without their faults. Users should consider these issues when deciding whether or not to purchase a Ryzen 1000 series CPU.
