[. . . ] No part of this manual may be reproduced, copied, translated, transmitted, or published in any form or by any means without GIGABYTE's prior written permission. „„ In order to assist in the use of this product, carefully read the User's Manual. „„ For product-related information, check on our website at: http://www. gigabyte. com Identifying Your Motherboard Revision The revision number on your motherboard looks like this: "REV: X. X. " For example, "REV: 1. 0" means the revision of the motherboard is 1. 0. Check your motherboard revision before updating motherboard BIOS, drivers, or when looking for technical information. [. . . ] When enabled, the CPU core frequency and voltage will be reduced when the CPU is overheated. Auto lets the BIOS automatically configure this setting. (Default: Auto) Enables or disables Enhanced Intel® Speed Step Technology (EIST). Depending on CPU loading, Intel EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. Auto lets the BIOS automatically configure this setting. (Default: Auto) Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled. (Default) Profile1  Uses Profile 1 settings. Profile2 (Note 2) Uses Profile 2 settings.  Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD data. (Default: Auto) The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the System Memory Multiplier settings. && Hyper-Threading Technology (Note 1) && CPU Enhanced Halt (C1E) (Note 1) && C3 State Support (Note 1) && C6/C7 State Support (Note 1) && CPU Thermal Monitor (Note 1) && CPU EIST Function (Note 1) && Extreme Memory Profile (X. M. P. ) (Note 2) && System Memory Multiplier && Memory Frequency (MHz) (Note 1) This item is present only when you install a CPU that supports this feature. This sub-menu provides memory timing settings for each channel of memory. The respective timing setting screens are configurable only when Memory Timing Mode is set to Manual or Advanced Manual. Note: Your system may become unstable or fail to boot after you make changes on the memory timings. If this occurs, please reset the board to default values by loading optimized defaults or clearing the CMOS values. `` Advanced Voltage Settings This sub-menu allows you to set CPU, chipset and memory voltages. (Note) This item is present only when you install a CPU and a memory module that support this feature. - 21 - `` PC Health Status && Reset Case Open Status Disabled  Keeps or clears the record of previous chassis intrusion status. (Default) Enabled   Clears the record of previous chassis intrusion status and the Case Open field will show "No" at next boot. Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Yes", otherwise it will show "No". To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to the CMOS, and then restart your system. Displays the current system voltages. && Case Open && CPU Vcore/CPU VRIN/DRAM Voltage/+3. 3V/+5V/+12V/CPU VAXG && CPU/System Temperature && CPU/System Fan Speed && CPU Fan Speed Control Displays current CPU/system temperature. Displays current CPU/system fan speeds. Allows you to determine whether to enable the fan speed control function and adjust the fan speed.
