ASRock Fatal1ty 990FX Professional User Manual - Page 11

CAUTION! 1. ASRock UCC (Unlock CPU Core) feature simplifies AMD CPU activation. As long as a simple switch of the UEFI option "ASRock UCC", you can unlock the extra CPU core to enjoy an instant performance boost. When UCC feature is enabled, the dual-core or triple-core CPU will boost to the quad-core CPU, and some CPU, including quad-core CPU, can also increase L3 cache size up to 6MB, which means you can enjoy the upgrade CPU performance with a better price. Please be noted that UCC feature is supported with AM3 CPU only, and in addition, not every AM3 CPU can support this function because some CPU's hidden core may be malfunctioned. 2. This motherboard supports Untied Overclocking Technology. Please read "Untied Overclocking Technology" on page 49 for details. 3. This motherboard supports Dual Channel Memory Technology. Before you implement Dual Channel Memory Technology, make sure to read the installation guide of memory modules on page 19 for proper installation. 4. Whether 2100MHz memory speed is supported depends on the AM3/ AM3+ CPU you adopt. If you want to adopt DDR3 2100 memory module on this motherboard, please refer to the memory support list on our website for the compatible memory modules. ASRock website: http://www.asrock.com 5. 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® 64-bit OS with 64-bit CPU, there is no such limitation. 6. For microphone input, this motherboard supports both stereo and mono modes. For audio output, this motherboard supports 2-channel, 4-channel, 6-channel, and 8-channel modes. Please check the table on page 15 for proper connection. 7. F-Stream is an all-in-one tool to fine-tune different system functions in a user-friendly interface, which currently includes Hardware Monitor, Fan Control, Overclocking, OC DNA, Mouse Polling and IES. In the Hardware Monitor mode, F-Stream shows the major readings of your system. In Fan Control mode, F-Stream shows the fan speed and temperature for you to adjust. In Overclocking Control mode, F-Stream allows you to overclock the CPU frequency for optimal system performance. In OC DNA mode, you can save your OC settings as a profile and share them with your friends. Your friends can then load the OC profile in to their own system to get the same OC settings. In Mouse Polling mode, F-Stream allows you to adjust the mouse polling rate of the Fatal1ty Mouse port to add a professional level mouse configuration. In IES (Intelligent Energy Saver) mode, the voltage regulator can reduce the number of output phases to improve efficiency when the CPU cores are idle without sacrificing computing performance. 11
