RAM tips
Populate DIMM slots A2 and B2 first on most Z690 or Z790 motherboards to ensure optimal dual-channel operation and stability.
Monitor memory voltage (VCCSA, VDD, VDDQ) in the BIOS to confirm stability, especially when pushing beyond standard XMP profiles, though DDR5-6000 typically runs well with XMP defaults.
Experiment with setting the memory controller to Gear 2 mode in the BIOS for DDR5-6000, as this often provides the best balance of performance and stability for Alder Lake processors at this speed.
Installation & XMP/EXPO
Always ensure you enable the Intel XMP 3.0 profile in your motherboard's UEFI/BIOS after installing DDR5-6000 modules to achieve the advertised speeds and timings.
