MSI P67A-GD55 (B3) manual

BIOS Setup

▶IntelTurbo Booster

This item will appear when you install a CPU with Intel Turbo Boost technology. This item is used to enable/ disable Intel Turbo Boost technology. It can scale processor frequency higher dynamically when applications demand more performance and TDP headroom exists. It also can deliver seamless power scalability (Dynamically scale up, Speed-Step Down). It is the Intel newly technology within newly CPU.

▶DRAM Ratio

This setting controls the ratio of memory frequency to enable the memory to run at dif- ferent frequency combinations.

▶Extreme Memory Profile(X.M.P)

This item is used to enable/disable the Intel Extreme Memory Profile (XMP). For further information please refer to Intel’s official website.

▶Adjusted DRAM Frequency

It shows the adjusted DRAM frequency. Read-only. ▶DRAM Timing Mode

Select whether DRAM timing is controlled by the SPD (Serial Presence Detect) EE- PROM on the DRAM module. Setting to [Auto] enables DRAM timings and the following “Advanced DRAM Configuration” sub-menu to be determined by BIOS based on the configurations on the SPD. Selecting [Link] or [Unlink] allows users to configure the DRAM timings and the following related “Advanced DRAM Configuration” sub-menu manually.

▶Advanced DRAM Configuration Press <Enter> to enter the sub-menu.

▶Command Rate2

This setting controls the DRAM command rate.

▶tCL

This controls the CAS latency, which determines the timing delay (in clock cycles) before SDRAM starts a read command after receiving it.

▶tRCD

When DRAM is refreshed, both rows and columns are addressed separately. This setup item allows you to determine the timing of the transition from RAS (row ad- dress strobe) to CAS (column address strobe). The less the clock cycles, the faster the DRAM performance.
