Dual Core Center DOT (Dynamic OverClocking) Dynamic Overclocking Technology is an automatic overclocking function, included in the MSITM ’s newly developed Dual CoreCenter Technology. It is designed to detect the loading of CPU/ GPU while running programs, and to over-clock automatically. When the motherboard detects that the loading of CPU is exceed the default threshold for a time, it will speed up the CPU and fan automatically to make the system run smoother and faster.
M S-7551 M ainboard Clock In the Clock sub-menu, you can see clock status (including FSB/ CPU clock of mainboard and GPU/ memory clock of graphics card) of your system. And you can select desired value for overclocking. There will be several items for you to select for overclocking after you click button. You can click the plus sign button to increase the clock, or click the minus sign button to decrease the clock. And finally, click the Apply button to apply the values adjusted.
Dual Core Center Voltage In the Voltage sub-menu, you can see voltage status (including Vcore, memory, GPU voltage... etc.) of your system, and you can select desired value for overclocking. It will show several items to select for overclocking after you click the button. You can click the plus sign button to increase the voltage, or click the minus sign button to decrease. And finally, click the Apply button to apply the adjustments.
M S-7551 M ainboard FAN Speed In the FAN Speed sub-menu, you can read fan status of your system. Select higher speed for better cooling effect. There are several sections for you to change the fan speed to a section after clicking button. Click the plus sign button to increase the fan speed to a section, or click the minus sign button to decrease. Or click the Default button to restore the default values. On the underside, it shows the graphs of the fan speed.
Dual Core Center Temperature In the Temperature sub-menu, you can see temperature status of your system. On the underside, it shows the graphs of the temperatures. Only the curves of the item which the button is lit up with red color will be shown.
M S-7551 M ainboard User Profile In the User Profile sub-menu, click the setting button that besides the user profile bar, and the next screen will appear. Here you can define the clock/ fan speed/ voltage by your need, click the button to choose a value quickly, or click the plus / minus sign button to increase/ decrease the value.
Dual Core Center Use the draw bar to set the max system temperature. W hen the system temperature exceeds the threshold you defined, the system will pop up a warning message and shut down the system. Use the draw bar to set the minimal fan speed. When the fan speed is lower than the threshold you defined, the system will pop up a warning message. After setting all values you need, you can change the user profile name in the box then click the save button to save all changes in a profile.
SATA RAID Appendix C SATA RAID The SB700/ 750 integrate one SATA host controller separately, and support RAID function for performance and reliability. SATA RAID provides support for RAID 0 (Striping), RAID 1 (Mirroring), RAID 0+1 (Striping & Mirroring) & RAID 5 (striping with parity). RAID 0 greatly improves hard disk I/O performance by concurrently striping data across multiple drives. RAID 1 makes sure data is not lost if a drive f ails as data is simultaneously written to two drives.
M S-7551 M ainboard RAID Configuration Creating and deleting RAID set and performing other RAID setting up operations are done in the RAID BIOS. During bootup, a screen similar to the one below will appear for about few seconds. Press to enter FastBuild utility. Important Be sure to enable the RAID function for SATA device in BIOS before configuring the Fastbuild Utility. The FastBuild menu screen will appear. The Main Menu is used to choose the operation to be performed.
SATA RAID View Drives Assignments This window displays the model number, capacities and assignment of the drives physically attached to the SATA host adapter.
M S-7551 M ainboard Define LD (Creating RAID) The selection of the RAID configuration should be based upon factors including performance, data security, and the number of drives available. It is best to carefully consider the long-term role of the system and plan the data storage strategy. RAID sets can be created either automatically, or to allow the greatest flexibility, manually. 1. Press 2 on the Main Menu screen to enter the Define LD Menu. 2.
SATA RAID • Stripe Block Size, the default 64KB is best for most applications. RAID 0 or 10 only. • Gigabyte Boundary, allows use of slightly smaller replacement drives. • Cache Mode, W riteThru or W riteBack. 4. On the Drives Assignments window, use the arrow key to choose the hard drives which you want to make part of the LD, use the space key to change the assignment to “Y”. Then press [Ctrl+Y] to save the configuration. 5.
M S-7551 M ainboard 6. The LD creation is done, the screen shows the LD information as below. Press ESC key to the main screen. 7. Press ESC key to exit the utility, a message “System is going to REBOOT! Are You Sure?” will display, answer “Y” to exit it and the system will reboot.
SATA RAID Delete LD (Deleting RAID) 1. Select “Delete LD” on the main screen. 2. Choose a LD No you want to delete and press “Del” or “Alt+D” delete the RAID set. 3. On the next screen, a message will display to inform you, press “Ctrl+Y” to delete the RAID set or other key to abort it. Press “Ctrl+Y” to complete the deletion.
M S-7551 M ainboard Installing the RAID Driver (for bootable RAID Array) For W indows XP: 1. After you complete the RAID BIOS setup, boot from the W indows CD, and the W indows XP Setup program starts. 2. Press F6 and wait for the W indows Setup screen to appear. 3. Insert the floppy that contains the RAID driver, press the “S” key to select “Specify Additional Device”. Important Please follow the instruction below to make a SATA RAID driver for yourself. 1. Insert the MSI CD into the CD-ROM drive. 2.
SATA RAID Installing the RAID Driver Under Windows (for Non-bootable RAID Array) 1. Insert the MSI CD into the CD-ROM drive. 2. The CD will auto-run and the setup screen will appear. 3. Under the Driver tab, click on ATI System Driver by your need. The ATI System Driver includes RAID Driver. 4. The driver will be automatically installed. Important You must install the RAID driver to enable RAID.
