WARNING Please realize that there is a certain risk involved with overclocking, including adjusting the setting in the BIOS, applying Untied Overclocking Technology, or using the third-party overclocking tools. Overclocking may affect your system stability, or even cause damage to the components and devices of your system. It should be done at your own risk and expense. We are not responsible for possible damage caused by overclocking. CAUTION! 1. About the setting of "Hyper Threading Technology", please check page 69. 2. This motherboard supports Quad Channel Memory Technology. Before you implement Quad Channel Memory Technology, make sure to read the installation guide of memory modules on page 21 for proper installation. 3. Due to Intel® CPU spec definition, please install the memory modules on DDR3_A1, DDR3_B1, DDR3_C1 and DDR3_D1 for the first priority. If above four DDR3 DIMM slots are fully installed, and you want to use more than four memory modules, please install the other memory modules from left to right (from DDR3_A2, DDR3_B2, DDR3_D2 to DDR3_ C2.) 4. Due to the operating system limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows® 7 / VistaTM / XP. For Windows® OS with 64-bit CPU, there is no such limitation. You can use ASRock XFast RAM to utilize the memory that Windows® cannot use. 5. Currently Intel® Socket 2011 Sandy Bridge-E Processor doesn't support PCIE 3.0, but this motherboard is already PCIE 3.0 hardware ready. It depends on Intel's CPU to enable PCIE 3.0. Please check Intel's website for information on future CPU updates and releases. 6. ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to ne-tune different system functions in a user-friendly interface, which includes Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hardware Monitor, it shows the major readings of your system. In Fan Control, it shows the fan speed and temperature for you to adjust. In Overclocking, you are allowed to overclock CPU frequency for optimal system performance. In OC DNA, you can save your OC settings as a profile and share it with your friends. Your friends then can load the OC profile to their own system to get the same OC settings. In IES (Intelligent Energy Saver), the voltage regulator can reduce the number of output phases to improve efficiency when the CPU cores are idle without sacrificing computing performance.
