HARDWARE SETUP CPU & Cooler Installation for LGA1155 When installing a CPU, always remember to install a CPU cooler.
MS-7808 Follow the steps below to install the CPU & cooler correctly. . Unhook and lift the loading lever to the fully open position. . The loading plate should automatically lift up as the loading lever is pushed to the fully open position. Do not touch any of the CPU socket pins. 3. Line up the CPU to fit the CPU socket. Be sure to hold the CPU by the base with the metal contacts facing downward. The alignment keys on the CPU will line up with the edges of the CPU socket to ensure a correct fit.
Mounting Screw Holes When installing the mainboard, first install the necessary mounting stands required for a mainboard on the mounting plate in your computer case. If there is an I/O back plate that came with the computer case, please replace it with the I/O backplate that came with the mainboard package. The I/O backplate should snap easily into the computer case without the need for any screws.
MS-7808 Installing Memory Modules . Unlock the DIMM slot by pushing the mounting clips to the side. Vertically insert the memory module into the DIMM slot. The memory module has an off-center notch on the bottom that will only allow it to fit one way into the DIMM slot. . Push the memory module deep into the DIMM slot. The plastic clips at each side of the DIMM slot will automatically close when the memory module is properly seat and an audible click should be heard. 3.
JPWR1: ATX 24-Pin Power Connector This connector allows you to connect an ATX 24-pin power supply. To connect the ATX 24-pin power supply, align the power supply cable with the connector and firmly press the cable into the connector. If done correctly, the clip on the power cable should be hooked on the mainboard’s power connector. d n u ro V .G 5 V 4 2 3.+ +5 V d 2 2. +5 s un d 2 . e o n d 1 2 0.R Gr rou un # 2 9. G ro ON d 1 8.

Current CPU / DRAM Frequency These items show the current clocks of CPU and Memory speed. Read-only. Adjust CPU Ratio Controls the multiplier that is used to determine internal clock speed of the processor. This feature can only be changed if the processor supports this function.
DRAM Frequency This item allows you to adjust the DRAM frequency. Please note the overclocking behavior is not guaranteed. 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) EEPROM 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.
MS-7808 tRTP Time interval between a read and a precharge command. tFAW This item is used to set the tFAW (four activate window delay) timing. tWCL This item is used to set the tWCL (Write CAS Latency) timing. tCKE This item is used to set the Pulse Width for DRAM module. tRTL This item is used to set Round Trip Latency settings. ==Advanced Timing Configuration== tRRDR Specifies the active-to-active delay of different ranks on the same DIMM. tRRDD Specifies the active-to-active delay of different DIMMs.
Active Processor Cores This item allows you to select the number of active processor cores. Limit CPUID Maximum It is designed to limit the listed speed of the processor to older operating systems. Execute Disable Bit Can prevent certain classes of malicious “buffer overflow” attacks where worms can try to execute code to damage your system. It is recommended you keep this enabled always. Intel Virtualization Tech Enhances virtualization and allows the system to act as multiple virtual systems.
