Kunpeng Server BIOS Optimization Methods
Set Performance Config
Default value: custom
Set Performance Config to Performance to ensure that the peak CPU frequency remains unchanged during computing.
Configuring the Memory Refresh Rate
Default value: 32ms
Set the memory refresh rate to Auto. In most cases, the memory refresh rate is 64ms, which reduces the interference with memory usage.
Adjusting CPU Hardware Prefetching
Default value: enabled
In GPU computing scenarios, most memory accesses are sequential and enabling prefetching can improve performance.
Disabling the SMMU
Default value: enabled
After the system memory management unit (SMMU) is enabled, the memory access passes through the MMU for address translation, which affects performance. You are advised to disable the SMMU.
