Do not mix memory kits. Memory kits are sold in matched kits that
are designed to run together as a set. Mixing memory kits will result in
stability issues or system failure.
Prior to enabling XMP, memory kits will boot at the SPD speed at default BIOS settings with compatible hardware.
For memory kits with XMP, enable XMP/DOCP/A-XMP profile in BIOS to
reach up to the rated potential XMP overclock speed of the memory kit,
subject to the use of compatible hardware. Enabling XMP is an act of
overclocking and requires BIOS setting adjustments. Please refer to the "How to Enable XMP/EXPO" guide.
Reaching the rated XMP overclock speed and system stability will
depend on the compatibility and capability of the motherboard and CPU
used.
Usage in any manner inconsistent with manufacturer specifications,
warnings, designs, or recommendations will result in lower speeds,
system instability, or damage to the system or its components.
