What memory frequency does linux support?

Linux’s support for memory frequency depends on the hardware and kernel version used. Modern Linux kernel can support very high memory frequencies, even exceeding DDR4 3200MHz. Therefore, when choosing a memory frequency, it is recommended to refer to the hardware manufacturer's recommendations and specifications and to ensure system stability and compatibility.

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

Linux support for memory frequencies depends on the hardware and kernel version used. Generally speaking, modern Linux kernels can support very high memory frequencies, even exceeding DDR4 3200MHz.

Memory frequency support also depends on the following factors:

1. Motherboard and processor support: To achieve higher memory frequencies, you must ensure that the motherboard and processor support the appropriate Specifications. Consult the motherboard and processor technical specifications manual for more detailed information.

2. Memory module specifications and configuration: The specifications and configuration of the memory module are also key factors. Make sure the selected memory modules are compatible with the system and adjust BIOS/UEFI settings if necessary to support higher frequencies.

3. Kernel Versions and Memory Controller Drivers: Newer Linux kernel versions generally provide better memory support, including higher frequencies. It is also important to ensure that the memory controller driver you are using is the latest version.

When the memory frequency exceeds a certain threshold, the following effects may occur:

1. Stability issues: High frequencies may cause the memory controller to fail Normal operation or stability is reduced, resulting in system crash or abnormal behavior.

2. Compatibility issues: Some combinations of motherboards, processors, and memory modules may not support ultra-high memory frequencies, causing the system to fail to start or run stably.

3. Limited performance improvement: Although the memory frequency increases, the actual performance improvement is not always linear. Other factors, such as latency and bandwidth, also have an impact on system performance.

Therefore, when choosing a memory frequency, it is recommended to refer to the hardware manufacturer's recommendations and specifications and ensure system stability and compatibility.
