1-Core Ratio Limit [Auto]
Congure the 1‑core ratio limit that must be higher than or equal to the 2‑core ratio limit.
2-Core Ratio Limit [Auto]
Congure the 2‑core ratio limit that must be higher than or equal to the 3‑core ratio limit. The
1‑core ratio limit must not be set to [Auto].
3-Core Ratio Limit [Auto]
Congure the 3‑core ratio limit that must be higher than or equal to the 4‑core ratio limit. The
1‑core and 2‑core ratio limit must not be set to [Auto].
4-Core Ratio Limit [Auto]
Congure the 4‑core ratio limit that must be lower than or equal to the 3‑core ratio limit. The
1‑core, 2‑core, and 3‑core ratio limit must not be set to [Auto].
2.5.2 BCLK Frequency: DRAM Frequency Ratio [Auto]
[Auto] The BCLK frequency to DRAM frequency ratio will be set to the optimized
setting.
[100:133] The BCLK frequency to DRAM frequency ratio will be set to 100:133.
[100:100] The BCLK frequency to DRAM frequency ratio will be set to 100:100.
2.5.3 DRAM Odd Ratio Mode [Enabled]
This item allows you to enable availability of odd DRAM ratios for improved granularity.
Conguration options: [Enabled] [Disabled]
2.5.4 DRAM Frequency [Auto]
This item allows you to select the DRAM operating frequency. The congurable options vary
with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized
setting.
Conguration options: [Auto][DDR4‑800MHz] [DDR4‑933MHz] [DDR4‑1066MHz]

[DDR4‑4133MHz] [DDR4‑4266MHz]
Selecting a very high memory frequency may cause the system to become unstable! If this
happens, revert to the default setting.
