MSI H61M-P31/W8 manual

tRAS

This setting determines the time RAS takes to read from and write to memory cell.

tRFC

This setting determines the time RFC takes to read from and write to a memory cell.

tWR

Minimum time interval between end of write data burst and the start of a pre- charge command. Allows sense amplifiers to restore data to cells.

tWTR

Minimum time interval between the end of write data burst and the start of a column-read command. It allows I/O gating to overdrive sense amplifiers before read command starts.

tRRD

Specifies the active-to-active delay of different banks.

tRTP

Time interval between a read and a precharge command.

tFAW

Press <Enter> to enter the sub-menu. And you can set the advanced memory timing for each channel.

GT OverClocking

This item allows you to enable/ disable the overclocking of integrated graphics.

GT Ratio

This setting controls the ratio of integrated graphics frequency to enable the inte- grated graphics to run at different frequency combinations.

Adjusted GT Frequency

It shows the adjusted integrated graphics frequency. Read-only.

Spread Spectrum

When the mainboard’s clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves.

Important

*If you do not have any EMI problem, leave the setting at [Disabled] for optimal system stability and performance. But if you are plagued by EMI, select the value of Spread Spectrum for EMI reduction.
