AVX2 Ratio Offset to per-core Ratio Limit Configuration options: [Auto] [User Specify] The following item appears only when AVX2 Ratio Offset to per-core Ratio Limit is set to [User Specify]. AVX2 Ratio Offset Specifies number of bins to decrease AVX ratio vs. Per-Core Ratio. AVX is a more stressful workload, it is helpful to lower the AVX ratio to ensure maximum possible ratio for SSE workloads. Uses Mailbox MSR 0x150, cmd 0x1B. Range 0-31. 0=No offset. Use the or to adjust the value. Configuration options: [0] - [31] AVX2 Voltage Guardband Scale Factor Configuration options: [Auto] [User Specify] The following item appears only when AVX2 Voltage Guardband Scale Factor is set to [User Specify]. AVX2 Voltage Guardband Scale Factor Controls the voltage guardband applied to AVX workloads. Range in 1/100 units, where 125=1.25 scale factor. The resulting final voltage guardband is default guardband * Scale Factor. Therefore lower than 100 values reduce guardband while higher than 100 values increase guardband. Use the or to adjust the value. Configuration options: [0] - [199] DRAM Timing Control The sub-items in this menu allow you to set the DRAM timing control features. Use the and keys to adjust the value. To restore the default setting, type [Auto] using the keyboard and press the key.

If this happens, revert to the default settings.
