1.1.3 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA2011-3 socket designed for Intel® Core™ i7 processors. • Ensure that all power cables are unplugged before installing the CPU. • Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components.
1.1.4 System memory The motherboard comes with eight (8) DDR4 (Double Data Rate 4) Quad Inline Memory Modules (DIMM) slots. A DDR4 module is notched differently from a DDR, DDR2, or DDR3 module. DO NOT install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.
Memory configurations You may install 2 GB, 4 GB and 8 GB unbuffered and non‑ECC DDR4 DIMMs into the DIMM sockets. • You may install varying memory sizes in Channel A, Channel B, Channel C, and Channel D. The system maps the total size of the lower-sized channel for the dualchannel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • According to Intel® CPU spec, DIMM voltage below 1.65 V is recommended to protect the CPU.
1.1.5 Expansion slots Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.

1.1.6 Onboard buttons and switches Onboard buttons and switches allow you to fine-tune performance when working on a bare or open-case system. This is ideal for overclockers and gamers who continually change settings to enhance system performance. 1. Power-on button The motherboard comes with a power-on button that allows you to power up or wake up the system.
3. MemOK! button Installing DIMMs that are not compatible with the motherboard may cause system boot failure. If the system fail to boot during POST stage and the DRAM_LED near the MemOK! button lights continuously, press the MemOK! button until the DRAM_LED starts blinking. System will begin automatic memory compatibility tuning and reboot for successful boot. Chapter 1 1-10 • Refer to section 1.1.8 Onboard LEDs for the exact location of the DIAG_DRAM LED.
4. EZ XMP switch Enable this switch to overclock the installed DIMMs, allowing you to enhance the DIMM’s speed and performance. The EZ XMP LED (XLED1) lights up when you enable the EZ XMP switch. For Chapter 1 the location of the EZ XMP LED, refer to section 1.1.8 Onboard LEDs.
1.1.7 1. Jumpers Clear RTC RAM jumper (2-pin CLRTC) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2.
2. CPU Over Voltage jumper (3-pin CPU_OV) Chapter 1 The CPU Over Voltage jumper allows you to set a higher CPU voltage for a flexible overclocking system, depending on the type of the installed CPU. To gain more CPU voltage setting, insert the jumper to pins 2-3. To go back to its default CPU voltage setting, insert the jumper to pins 1-2.
1.1.8 1. Onboard LEDs POST State LEDs The POST State LEDs provide the status of these key components during POST (Power-On Self-Test): CPU, memory modules, VGA card, and hard disk drives. If an error is found, the critical component’s LED stays lit up until the problem is solved. 2. EZ XMP LED (XLED1) This LED lights up when you enable the EZ XMP switch.
3. Standby Power LED (PWR_LED) The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down the system and unplug the power cable before removing or plugging any motherboard components. The illustration below shows the location of the onboard LED. 4. Q-Code LEDs Chapter 1 The Q-Code LED design provides you with a 2-digit error code that displays the system status.
