What are the memory modes of gear1 and gear2?

gear1 and gear2 memory modes refer to the proportional relationship between the CPU's memory controller and the memory frequency; gear1 indicates that the ratio of the memory controller frequency and the memory operating frequency is "1:1", while gear2 indicates the memory control The ratio of the processor frequency and the memory operating frequency is "1:2", which can reduce the pressure on the memory controller and make it easier for the memory to obtain higher frequencies.

What are the memory modes of gear1 and gear2?

The memory Gear1 and Gear2 often refer to the proportional relationship between the CPU's memory controller and the memory frequency. If the CPU memory Controller frequency: When the memory frequency is 1:1, it is called Gear1. If the ratio is 1:2, it is Gear2.

The memory operating frequency is restricted by the memory controller. The memory controller is an area of ​​​​the CPU that controls the memory and is responsible for controlling the work of the memory. The cache structure of modern processors is complex. Improving the read and write performance of externally accessed memory can be said to be a technical problem that affects the whole body. So AMD and Intel both took a similar path: adding frequency dividers. The original 1:1 synchronous frequency division is changed to an asynchronous frequency division mechanism that automatically switches to 1:2 at high frequencies.

What is the specific working mode of memory frequency division?

##In CPU-Z, you can see the difference between Gea1 and Gear2 modes

Under the memory frequency division mechanism, there are "Gear1 mode" and "Gear2 mode". Gear1 mode is 1:1. The ratio of the memory controller frequency and the memory operating frequency is 1:1. The two work synchronously, with low memory latency and maximum performance. The Gear2 mode is 1:2. The frequency of the memory controller is only half of the memory frequency, which can reduce the pressure on the memory controller and make it easier for the memory to obtain higher frequencies.
