BIOS Setup

▶My OC Genie

This item is used to select whether OC Genie parameters are customized by user. Setting to [MSI] OC Genie will use default OC related parameters to overclock the system. Selecting [Customize] allows you to configure the following related “My OC Genie option” sub-menu manually for OC Genie.

▶My OC Genie option

Press <Enter> to enter the sub-menu. ▶My OC Genie GT Overclocking

This item allows you to enable/ disable the overclocking of integrated graphics for My OC Genie function.

▶My OC Genie GT Ratio

This item allows you to specific the GT ratio for My OC Genie function.

▶Adjusted My OC Genie GT Frequency

It shows the iGPU frequency when OC Genie is started. Read-only.

▶DRAM Reference Clock

This item allows you to specific the DRAM Reference Clock for CPU. Please note the overclocking behavior is not guaranteed.

▶DRAM Frequency

▶tCL

Controls CAS latency which determines the timing delay (in clock cycles) of starting a read command after receiving data.

▶tRCD

Determines the timing of the transition from RAS (row address strobe) to CAS (col- umn address strobe). The less clock cycles, the faster the DRAM performance.

▶tRP

Controls number of cycles for RAS (row address strobe) to be allowed to pre-charge. If insufficient time is allowed for RAS to accumulate before DRAM refresh, the DRAM
