CPU (Central Processing Unit)

This mainboard supports Intel® processor in LGA 775 package. W hen you areinstalling the CPU, make sure to install the cooler to prevent overheating. If you do nothave the CPU cooler, consult your dealer before turning on the computer.(For the latest information about CPU, please visit http://global.msi.com.tw/index.php?func=cpuform)

Introduction to LGA 775 CPUThe surface of LGA 775 CPU.Remember to apply some ther-mal paste on it for better heatdispersion.

Important

OverheatingOverheating will seriously damage the CPU and system. Always make surethe cooling fan can work properly to protect the CPU from overheating. Makesure that you apply an even layer of thermal paste (or thermal tape) betweenthe CPU and the heatsink to enhance heat dissipation.Replaceing the CPUWhile replacing the CPU, always turn off the ATX power supply or unplug thepower supply’s power cord from the grounded outlet first to ensure the safetyof CPU.OverclockingThis mainboard is designed to support overclocking. However, please makesure your components are able to tolerate such abnormal setting, whiledoing overclocking. Any attempt to operate beyond product specifications isnot recommended. We do not guarantee the damages or risks causedby inadequate operation or beyond product specifications.

Important

1. Confirm if your CPU cooler is firmly installed before turning on your system.2. Do not touch the CPU socket pins to avoid damaging.3. The availability of the CPU land side cover depends on your CPU packing.

2. Remove the cap from lever hingeside (as the arrow shows).

1. The CPU socket has a plastic capon it to protect the contact fromdamage. Before you install the CPU,always cover it to protect the socketpin.

CPU & Cooler InstallationWhen you are installing the CPU, make sure the CPU has a cooler attached onthe top to prevent overheating. Meanwhile, do not forget to apply some thermalpaste on CPU before installing the heat sink/cooler fan for better heat dispersion.Follow the steps below to install the CPU & cooler correctly. Wrong installation willcause the damage of your CPU & mainboard.

3. The pins of socket reveal. 4. Open the load lever.

Hardware Setup

6. After confirming the CPU directionfor correct mating, put down theCPU in the socket housing frame.Be sure to grasp on the edge ofthe CPU base. Note that the align-ment keys are matched.

8. Cover the load plate onto thepackage.

7. Visually inspect if the CPU isseated well into the socket. If not,take out the CPU with pure verticalmotion and reinstall.

12. Turn over the mainboard to con-firm that the clip-ends are cor-rectly inserted.

11. Press the four hooks down to fas-ten the cooler. Then rotate the lock-ing switch (refer to the correct di-rection marked on it) to lock thehooks.

9. Press down the load lever lightlyonto the load plate, and then se-cure the lever with the hook underretention tab.

Important

1. Read the CPU status in BIOS (Chapter 3).2. Whenever CPU is not installed, always protect your CPU socket pin with the

plastic cap covered (shown in Figure 1) to avoid damaging.3. Mainboard photos shown in this section are for demonstration of the CPU/

cooler installation only. The appearance of your mainboard may vary depend-ing on the model you purchase.

Memory

These DIMM slots are used for installing memory modules.(For more information on compatible components, please visit http://global.msi.com.tw/index.php?func=testreport)

Due to chipset limitations, to enable dual channel mode or single channel mode,installing memory modules should refer to the following table.

Important

You can barely see the golden finger if the memory module is properly insertedin the DIMM slot.

Volt Notch

Important

- DDR2 memory modules are not interchangeable with DDR and the DDR2standard is not backwards compatible. You should always install DDR2memory modules in the DDR2 DIMM slots.

- In Dual-Channel mode, make sure that you install memory modules of thesame type and density in different channel DIMM slots.

- To enable successful system boot-up, always insert the memory modulesinto the DIMM1 first.

- Due to the chipset resource deployment, the system density will only bedetected up to 3+GB (not full 4GB) when each DIMM is installed with a 1GBmemory module.

Installing Memory Modules1. The memory module has only one notch on the center and will only fit in the right

orientation.2. Insert the memory module vertically into the DIMM slot. Then push it in until the

golden finger on the memory module is deeply inserted in the DIMM slot. The plasticclip at each side of the DIMM slot will automatically close when the memory moduleis properly seated.

3. Manually check if the memory module has been locked in place by the DIMM slotclips at the sides.

Configure DRAM Timing by SPDSetting to [Enabled] enables DRAM CAS# Latency automatically to be determinedby BIOS based on the configurations on the SPD (Serial Presence Detect) EEPROMon the DRAM module.

DRAM CAS# LatencyWhen the Configuration DRAM Timing by SPD sets to [Disabled], the field isadjustable.This controls the CAS latency, which determines the timing delay (inclock cycles) before SDRAM starts a read command after receiving it.

DRAM RAS# to CAS# DelayWhen the Configuration DRAM Timing by SPD sets to [Disabled], the field isadjustable. When DRAM is refreshed, both rows and columns are addressedseparately. This setup item allows you to determine the timing of the transitionfrom RAS (row address strobe) to CAS (column address strobe). The less theclock cycles, the faster the DRAM performance.

DRAM RAS# PrechargeWhen the Configuration DRAM Timing by SPD sets to [Disabled], this field isadjustable. This setting controls the number of cycles for Row Address Strobe(RAS) to be allowed to precharge. If insufficient time is allowed for the RAS toaccumulate its charge before DRAM refresh, refresh may be incomplete andDRAM may fail to retain data. This item applies only when synchronous DRAM isinstalled in the system.

Spread SpectrumWhen the motherboard’s clock generator pulses, the extreme values (spikes) of thepulses create EMI (Electromagnetic Interference). The Spread Spectrum functionreduces the EMI generated by modulating the pulses so that the spikes of the pulsesare reduced to flatter curves. If you do not have any EMI problem, leave the setting atDisabled for optimal system stability and performance. But if you are plagued by EMI,set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you areoverclocking because even a slight jitter can introduce a temporary boost in clockspeed which may just cause your overclocked processor to lock up.

1. The greater the Spread Spectrum value is, the greater the EMI is reduced,and the system will become less stable. For the most suitable SpreadSpectrum value, please consult your local EMI regulation.

2. Remember to disable Spread Spectrum if you are overclocking becauseeven a slight jitter can introduce a temporary boost in clock speed whichmay just cause your overclocked processor to lock up.

DOT (Dynamic OverClocking)

Dynamic Overclocking Technology is an automatic overclocking function, included inthe MSITM’s newly developed Dual CoreCenter Technology. It is designed to detect theloading of CPU/ GPU while running programs, and to over-clock automatically. Whenthe motherboard detects that the loading of CPU is exceed the default threshold for atime, it will speed up the CPU and fan automatically to make the system run smootherand faster. When the graphics card detects that the loading of GPU is exceed thedefault threshold for a time, it will speed up the GPU, memory, fan and voltageautomatically to make the system run smoother and faster. When the CPU/ GPU istemporarily suspending or staying in low loading balance, it will restore the defaultsettings instead. Usually the Dynamic Overclocking Technology will be powered onlywhen users' PC runs huge amount of data, like 3D games or video process, and themotherboard/ graphicd card need to be boosted up to enhance the overall performance.There will be several selections when you click the DOT rate button (include increaserate and decrease rate buttons), to select the DOT level, then you have toclick the DOT button to apply the DOT function.
