Asus z170i pro gaming [54/86] Bclk frequency dram frequency ratio auto

2-20

Chapter 2: Getting started

3-Core Ratio Limit [Auto]

Select [Auto] to apply the CPU default Turbo Ratio setting or manually assign a 3‑Core Limit

value that must be higher than or equal to the 4‑Core Ratio Limit.

If you assign a value for 3‑Core Ratio Limit, do not set the 1‑Core Ratio Limit and 2‑Core

Ratio Limit to [Auto].

4-Core Ratio Limit [Auto]

Select [Auto] to apply the CPU default Turbo Ratio setting or manually assign a 4‑Core Limit

value that must be higher than or equal to the 3‑Core Ratio Limit.

If you assign a value for 4‑Core Ratio Limit, do not set the 1‑Core Ratio Limit, 2‑Core Ratio

Limit, and 3‑Core Ratio to [Auto].

2.5.4 BCLK Frequency: DRAM Frequency Ratio [Auto]

Allows you to set the CPU bus speed to DRAM speed ratio mode.

[Auto] DRAM speed is set to the optimized settings.

[100:133] The BCLK frequency to DRAM speed ratio is set to 100:133.

[100:100] The BCLK frequency to DRAM speed ratio is set to 100:100.

2.5.5 DRAM Odd Ratio Mode [Enabled]

Allows you to enable or disable the DRAM Odd Ratio Mode, which provides better

granularity. Conguration options: [Disabled] [Enabled]

2.5.6 DRAM Frequency [Auto]

This item allows you to set the memory operating frequency. The congurable options vary

with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized

setting. Conguration options: [DDR4‑800MHz] [DDR4‑933MHz] [DDR4‑1066MHz] [DDR4‑

1200MHz] [DDR4‑1333MHz] [DDR4‑1400MHz] [DDR4‑1500MHz] [DDR4‑1600MHz] [DDR4‑

1700MHz]

Selecting a very high memory frequency may cause the system to become unstable! If this

happens, revert to the default setting.

2.5.7 TPU [Keep Current Settings]

TPU automatically overclocks frequency and voltage of CPU and DRAM to enhance the

system performance.

[Keep Current Settings] Keep the current settings without changing anything.

[TPU I] Applies air cooling overclocking conditions.

[TPU II] Applies water cooling overclocking conditions. Ensure that you

use a water cooling device before selecting the TPU II mode.
