Here is the simple breakdown to get you up and running:
1. Flash the BIOS First
Because this board released earlier than the 13th-gen chips, you will have to update your BIOS only to have it recognize your i9.
The fix? Press the I/O back panel button which says BIOS Flashback. No processor or memory required, simply insert a USB with the latest software on the MSI web site.
2. Taming the i9 Heat
i9-13900K prefers to blow the power out.
The fix? In the BIOS, find CPU Lite Load. Switch to Mode 9 or less to reduce the temperatures significantly with no significant damage to the performance. It reduces the pressure on the power system of the board.
3. Solving XMP Drama
The initial versions of Z690 BIOS were slightly picky with high speed DDR4.
The fix? When you have installed the BIOS, switch on XMP Profile 1. When everything is wobbly, then make a manual setting of Gear 1 when you have less than 3600 MHz of RAM or Gear 2 when you are approaching 4000 MHz. That normally prevents crashes or no boot accidents.
4. Cooling is Key
The MSI Pro Z690-A DDR4 does not grab turret-size heat sinks as the $500 models.
The fix? Ensure that you have at least one exhaust fan in the top of your case by the CPU socket to blow away the heat out of those VRM heat-sinks.
