1. CPU socket The motherboard comes with a LGA1200 socket designed for 10th Gen Intel® Core™, Pentium® Gold and Celeron® processors. Chapter 1 1-4 • Ensure that you install the correct CPU designed for LGA1200 socket only. DO NOT install a CPU designed for other sockets on the LGA1200 socket. • The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU.
2. DIMM slots The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR4 (Double Data Rate 4) memory modules. Chapter 1 A DDR4 memory 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 4 GB, 8 GB, 16 GB, and 32 GB unbuffered and non‑ECC DDR4 DIMMs into the DIMM sockets. Chapter 1 You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
3. Expansion slots Chapter 1 Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. Please refer to the following tables for the recommended VGA configuration and Hyper M.2 configuration.
Recommended VGA configuration Chapter 1 Slot Description 1. PCIe 3.0 x16_1 3. PCIe 3.0 x16_2 Single VGA x16 N/A Dual VGA X16 x4 • We recommend that you provide sufficient power when running CrossFireX™ mode. • Ensure to connect the 8-pin and 4-pin power plugs when running CrossFireX™ mode. • Connect a chassis fan to the chassis fan connectors when using multiple graphics cards for better thermal environment. Hyper M.2 X16 series card configuration Slot Description 1. 1-8 PCIe 3.
4. Fan and Pump headers Chapter 1 The Fan and Pump headers allow you to connect fans or pumps to cool the system. • DO NOT forget to connect the fan cables to the fan headers. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! Do not place jumper caps on the fan headers! • Ensure the cable is fully inserted into the header. For water cooling kits, connect the pump connector to the W_PUMP+ header.
5. VRM Heatsink fan header The VRM Heatsink fan header is for connecting the VRM Heatsink fan on the integrated heatsink.
6. Power connectors Chapter 1 These Power connectors allow you to connect your motherboard to a power supply. The power supply plugs are designed to fit in only one orientation, find the proper orientation and push down firmly until the power supply plugs are fully inserted. Ensure to connect the 8-pin power plug. • For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12V Specification 2.0 (or later version) and provides a minimum power of 350 W.
7. M.2 slot The M.2 slot allows you to install M.2 SSD modules. Chapter 1 • M.2_1 slot supports PCIe 3.0 x4 mode Key M design and type 2242 / 2260/ 2280 / 22110 storage devices. • M.2_2 slot supports PCIe 3.0 x4 and SATA mode Key M design and type 2242 / 2260 / 2280 storage devices. • M.2 slots supports IRST (Intel® Rapid Storage Technology). The M.2 SSD module is purchased separately.
8. SATA 6Gb/s ports Chapter 1 The SATA 6Gb/s ports allows you to connect SATA devices such as optical disc drives and hard disk drives via a SATA cable. If you installed SATA storage devices, you can create a RAID 0, 1, 5, and 10 configuration with the Intel® Rapid Storage Technology through the onboard Intel® Z490 chipset. 9. • The slots are set to [AHCI] by default.
10. USB 3.2 Gen 1 header The USB 3.2 Gen 1 header allows you to connect a USB 3.2 Gen 1 module for additional USB 3.2 Gen 1 ports. The USB 3.2 Gen 1 header provides data transfer speeds of up to 5 Gb/s. Chapter 1 The USB 3.2 Gen 1 module is purchased separately. 11. USB 2.0 header The USB 2.0 header allows you to connect a USB module for additional USB 2.0 ports. The USB 2.0 header provides data transfer speeds of up to 480 Mb/s connection speed. DO NOT connect a 1394 cable to the USB connectors.
12. AURA Addressable Gen2 header Chapter 1 The Addressable Gen2 header allows you to connect individually addressable RGB WS2812B LED strips or WS2812B based LED strips. The Addressable Gen2 header supports WS2812B addressable RGB LED strips (5V/ Data/Ground), with a maximum power rating of 3A (5V), and the addressable headers on this board can handle a combined maximum of 500 LEDs.
13. AURA RGB header The AURA RGB header allows you to connect RGB LED strips. Chapter 1 The AURA RGB header supports 5050 RGB multi-color LED strips (12V/G/R/B), with a maximum power rating of 3A (12V). Before you install or remove any component, ensure that the power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components. 1-16 • Actual lighting and color will vary with LED strip.
14. Clear CMOS header Chapter 1 The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM in the CMOS, which contains the date, time, system passwords, and system setup parameters. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds. 3. Plug the power cord and turn ON the computer. 4. Hold down the key during the boot process and enter BIOS setup to re-enter data.
15. CPU Over Voltage jumper 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). Set to pins 2-3 to increase the CPU voltage setting, or set to pins 1-2 to use the default CPU voltage setting. 16. Front Panel Audio header The front panel audio header is for a chassis-mounted front panel audio I/O module that supports HD Audio. Connect one end of the front panel audio I/O module cable to this header.
17. System Panel header Chapter 1 The System Panel header supports several chassis-mounted functions. • System Power LED header (PLED) The 2-pin header allows you to connect the System Power LED. The System Power LED lights up when the system is connected to a power source, or when you turn on the system power, and blinks when the system is in sleep mode. • Storage Device Activity LED header (HDD_LED) The 2-pin header allows you to connect the Storage Device Activity LED.
18. Thermal Sensor header Chapter 1 The Thermal Sensor header allows you to connect a sensor to monitor the temperature of the devices and the critical components inside the motherboard. Connect the thermal sensor and place it on the device or the motherboard’s component to detect its temperature. The thermal sensor is purchased separately. 19. Q-LEDs The Q-LEDs check key components (CPU, DRAM, VGA, and booting devices) during the motherboard booting process.
20. 8-pin Power Plug LED Chapter 1 The 8-pin Power Plug LED lights up to indicate that the 8-pin power plug is not connected.
