Central Processing Unit (CPU)

This motherboard features an AMD AM4 socket designed for AMD Ryzen™ 2nd Generation, Ryzen™ with Radeon™ Vega Graphics, and Ryzen™ 1st Generation processors.

⚠️ Unplug all power cables before installing the CPU.

The AM4 socket has a different pinout from FM2+/FM2 sockets. Ensure you use an AM4-compatible CPU. The CPU fits in only one orientation. DO NOT force the CPU into the socket to prevent bending pins and damaging the CPU.

Installing the CPU

1. Lift the CPU socket lever.
2. Align the CPU's triangle marker with the socket's triangle marker and gently place the CPU into the socket.
3. Lower the CPU socket lever to secure the CPU.
4. Apply Thermal Interface Material (TIM) to the CPU heatsink and CPU before installing the heatsink and fan, if necessary.

Installing the CPU heatsink and fan assembly

Type 1 Installation: Follow the visual steps provided in the manual for Type 1 heatsink installation.

Type 2 Installation: Follow the visual steps provided in the manual for Type 2 heatsink installation. Remove only the screws and retention module; do not remove the plate on the bottom.

System memory

This motherboard has four DDR4 Dual Inline Memory Module (DIMM) sockets. The sockets are arranged as follows:

• Channel A: DIMM_A1 and DIMM_A2*
• Channel B: DIMM_B1 and DIMM_B2*

• You can install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for dual-channel configuration. Excess memory from the higher-sized channel is mapped for single-channel operation.
• For optimal compatibility, install DIMMs with the same CAS latency, version, or date code (D/C) from the same vendor. Check with your retailer for correct memory modules.
• For system stability, use an efficient memory cooling system when installing four DIMMs.
• Refer to www.asus.com for the latest Memory QVL (Qualified Vendors List).

Recommended memory configuration

The manual illustrates recommended memory configurations for dual-channel operation, showing specific DIMM slot population.

Installing a DIMM

To install a DIMM:

1. Open the retention clips on the DIMM socket.
2. Align the DIMM notch with the socket key and press down firmly on both ends until the retention clips snap into place.

To remove a DIMM:

1. Press down on the retention clips at both ends of the DIMM socket.
2. Gently pull the DIMM straight up and out of the socket.

Chapter 2: BIOS information

The BIOS setup program allows you to update the BIOS or configure system parameters. Navigation keys and brief online help are provided.

⚠️ Before using the ASUS CrashFree BIOS 3 utility, rename the BIOS file in the removable device to TB450PSG.CAP.

Entering BIOS Setup

• At startup: Press <Delete> or <F2> during the Power-On Self Test (POST).
• After POST: Press <Ctrl>+<Alt>+<Del> simultaneously, or press the system chassis reset button. If these fail, power off and on again.

⚠️ Forcing a reset from a running OS using power button, reset button, or <Ctrl>+<Alt>+<Del> can damage data or the system. Always shut down properly from the OS.

• BIOS setup screens are for reference only and may differ slightly.
• Download the latest BIOS file from www.asus.com.
