IMPORTANT BIOS FEATURES FOR OVERCLOCKING
Advanced BIOS Features
- CPU Enhanced Halt (C1E): Enables or disables Intel's power-saving function; when enabled, the CPU core frequency and voltage are throttled down to conserve power during system halt state.
- CPU Thermal Monitor (TM2): Enables or disables Intel's overheat protection function; when enabled, the CPU core frequency and voltage are throttled down when the CPU overheats.
- CPU EIST Function (SpeedStep): Enables or disables Intel's power-saving function; when enabled, the CPU core frequency and voltage are throttled down to conserve power dynamically during usage.
- Virtualization Technology: Enables or disables Intel's Virtualization technology which allows a platform to run multiple operating systems and applications in independent partitions.
- CPU Smart FAN Control: Enable or disable the motherboard's control over the processor fan. Disabling this feature will force the CPU fan to operating at 100% duty cycle.
- CPU Smart FAN Mode: Auto allows BIOS to detect optimal fan control mode. Voltage sets the Voltage mode for a 3-pin CPU fan. PWM Sets PWM mode for a 4-pin CPU fan.
- CPU Clock Ratio: Allows you to alter the clock ratio for the installed CPU.
- CPU Host Clock Control: Enables or disables the control of CPU host clock. Enabled will allow the CPU Host Frequency
- item below to be configurable.
- CPU Host Frequency (Mhz): Allows you to manually set the CPU host frequency.
- PCI Express Frequency(Mhz): Allows you to manually set the PCIe clock frequency.
- System Memory Multiplier: Allows you to set the system memory multiplier.
- System Voltage Control: Determines whether to manually set the system voltages.
- DDR2 OverVoltage Control: Allows you to set the memory voltage.
- PCI-E OverVoltage Control: Allows you to set the PCIe bus voltage.
- FSB OverVoltage Control: Allows you to set the Front Side Bus voltage.
- (G)MCH OverVoltage Control: Allows you to set the North Bridge voltage.
- CPU Voltage Control: Allows you to set the CPU voltage.
CAUTION!
Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.)
OVERCLOCKING TIPS
First and foremost, it is recommended that you check out the Ultimate Overclock.net Guide Compilation before starting to overclock. Many people read through the forum, see someone else with their chip, and just jump into high settings and then have to ask why it isn't working. If you read through those guides and these tips, you shouldn't need to ask many questions to get it working properly.
Here's a few tips to get you started overclocking:
- Lock your PCIe bus at 100mhz (It says it does this when it is set to 'Auto' but it's better safe then sorry.)
- Set your memory multiplier to 2.00. (It's there, trust me, partway down the list).
- Disable your Smart Fan Control in order to run your processor fan at 100% duty cycle at all times.
- Disable Intel's Speedstep so that you can see what your processor runs at max.
- Change all the 'performance enhance' and 'vga booster' functions to their standard/disabled/auto settings.
- Always set your voltages manually so that you're sure whats happening with them.
FAQS
- Help! My computer won't boot after I tried to modify settings in BIOS!
You're going to have to reset CMOS by hand. There are two methods of doing this: Remove the CMOS battery located on the motherboard and replace it after 1 minute, and jumping two pins on the motherboard that act as a reset switch when using a jumper.
- Help! My BIOS allows me to change settings but they don't stick once I've gotten to the operating system!
Unfortunately this is a frequent problem that seems to occur for several different reasons. The most reliable fix is to remove the CMOS battery as shown above after restoring the default settings in the BIOS. Some have also found that USB storage devices cause problems with booting, so try removing any USB storage devices attached.
- My computer seems to POST fine but it crashes when its loading the operating system.
Most likely you're not giving the processor enough voltage for the overclock you're trying to produce.
- How do I unlock the ability to modify Memory Timings?
Press CTRL-F1 at the main BIOS screen in order to unlock these settings in the Motherboard Intelligence Tweaker menu.
- How far can I push my 'xxxx' chip?
All chips are capable of performing differently. Many of the chips produced by manufacturers are actually from the same batch; they are sold with different model numbers in accordance to their most stable rating. With this in mind, you need to test yours yourself to see how far you can really push it.
- Should I flash my BIOS?
If you aren't having trouble with your BIOS for any reason, it's not recommended to flash it. Losing power while flashing your BIOS could potentially brick your motherboard.
- I set my clock and multiplier for xx settings and it occasionally runs much slower until I load a program.
Intel Speedstep is throttling your processor. Check the BIOS section above for more information (including how to disable it).
- Is there any fix for the large vdroop/vdrop on this board?
Yes, but it is a hardware volt mod and could void your warranty. Check out the link below for details on how to proceed. Note: The mod is for Rev 2.0 (Thanks to Rpg2 for this info!)
