Create a RAID volume (0, 1, 5, or 10) and select the drives. Then install the RAID drivers during Windows installation.

How to connect the front panel LEDs and switches?

Locate the PANEL1 header (9 pins) on the board. Connect the case cables respecting polarity: PWRBTN (switch), RESET, HDLED (HDD LED), PLED (power LED). The layout is printed on the board and in the manual. Use tweezers if necessary.

What types of RAM are supported?

The board supports DDR4 unbuffered non-ECC (or UDIMM ECC functioning as non-ECC) with frequencies up to 4500 MHz via overclocking. Four dual-channel DIMM slots, maximum capacity of 128 GB. Check the compatibility list on the ASRock website for validated modules. Enable XMP 2.0 in the BIOS to reach the advertised frequencies.

How to use the RGB LED headers?

The board has two RGB LED headers (4-pin, 12V) and two addressable headers (3-pin, 5V). Connect your LED strips respecting the arrow (polarity). Use ASRock Polychrome RGB software to customize effects. Do not exceed 3A/36W for 12V and 3A/15W for 5V. Never connect a 5V strip to a 12V header.

What to do if the motherboard does not boot?

Check that all power cables are properly connected (24-pin and 8/4-pin CPU). Test with a single RAM stick in slot A2 (second from the CPU). Verify that the processor is correctly installed. Try clearing the CMOS (CLRMOS1 jumper or battery removal) to reset the BIOS. Check the case diagnostic LEDs if present.

How to overclock the CPU on this motherboard?

Use an unlocked processor (K-series) and good cooling. Enter the BIOS, go to OC Tweaker. Gradually increase the CPU ratio (multiplier) and Vcore voltage. Monitor temperature with software. Enable XMP profiles for memory. Test stability with Prime95 or Cinebench. Overclocking is done at the user's own risk.

Where to download drivers for the Z490M Pro4?

Short

Open

Clear CMOS Jumper (CLRMOS1)

(see p.1, No. 18)

2-pin Jumper

CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper cap to short the pins on CLRMOS1 for 5 seconds. However, please do not clear the CMOS right after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action. Please be noted that the password, date, time, and user default profile will be cleared only if the CMOS battery is removed. Please remember to remove the jumper cap after clearing the CMOS.

If you clear the CMOS, the case open may be detected. Please adjust the BIOS option "Clear Status" to clear the record of previous chassis intrusion status.
