· 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. · Memory kits will boot at the SPD speed at default BIOS settings with compatible hardware. · For memory kits with XMP/EXPO, enable XMP/EXPO/DOCP/A-XMP profile in BIOS to reach the rated potential XMP/EXPO overclock speed of the memory kit, subject to the use of compatible hardware. Please refer to the "How to Enable XMP/EXPO" guide. · Reaching the rated XMP/EXPO 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. · Memory module height can be found in the FAQ, under the question "How tall are the memory modules?". · For product support and related questions, please contact the G.SKILL technical support team via email. |
