BIOSTAR

Recommendation for Overclocking test :

1. Using a high quality CPU Cooling FAN is suggested. Better CPU Cooling Solution should be very helpful for Overclocking. It is recommended to use Black edition Athlonx2 5000+ or 5400+.

2. High Quality Memory Module can also be a factor that infects the Overclocking performance.

Overclocking is an optional process, but not a "must-do" process; it is not recommended for inexperienced users. Therefore, we will not be responsible for any hardware damage which may be caused by overclocking. We also would not guarantee any overclocking performance.

	> In BIOS boot screen (POST), press DEL to enter BIOS Setup Utility.
	> Go to the Advanced menu and enter CPU Configuration; set the item "Cool N Quiet" to Disabled.
	> Go to the Chipset menu and enter AMD 790GX Configuration.
	> Enter Internal Graphics Configuration and choose "UMA" from Internal Graphics Mode * The UMA mode Allocates memory for the onboard graphics controller from the system memory.
	> Go to the T-series menu, and there are 3 modes for Overclocking: Normal Mode Automate Overclock Mode Manual Overclock Mode
	> 3 kinds of OC mode are preset under Automate Overclock Mode. > V6/V8/V12 is for different Overclocking performance in Biostar Tuning.
	> Manual Overclock Mode allows Overclockers doing OC step by step.
	> CPU/HT reference Clock (MHz) allows selecting CPU Overclock from 100MHz to 600MHz
	> CPU configuration allows selecting different CPU configuration from Configure 1 to Configure 7
	> CPU Enter CPU FID/VID control; set "Custom P-States" to Enabled
	> Set Core FID to 6.5X or 7.5X Note: Core FID Items will be changed with different CPU
	> Enter Voltage configuration for setting CPU Over Voltage / Memory Over Voltage / Chipset Over Voltage / HT Over Voltage / SidePort Votlage * Auto lets BIOS automatically set the system voltages as required. Manual allows all voltage control items below to be configurable.
	> CPU Over Voltage: from StartUp to +0.787V
	> Memory Over Voltage: from 1.9V to 2.6V
	> Chipset Over Voltage: from 1.2V to 1.5V
	> HT Over Voltage: from 1.2V to 1.5V
	> Side Port Voltage: 1.8V or Follow DDR Voltage * This item allows you to set the SidePort memory voltage.
	> Enter Dram Timing Configuration for setting Memory Clock Mode & DRAM Timing Mode
	> Enter Memory Clock Mode and choose Manual, there are 5 kinds of DDR2 frequency for extreme DDR2 memory performance. Ex.: 200MHz (DDR2-400) 266MHz (DDR2-533) 333MHz (DDR2-667) 400MHz (DDR2-800) 533MHz (DDR2-1066) Note: DDR2-1066 is available while using AM2+ CPU.
	> Enter DRAM Timing Mode and choose Both; there are several DRAM timing adjustable: CAS Latency(CL): Auto, 3, 4, 5, 6, 7 CLK 2T Command: Auto, 1T, 2T TRCD: Auto, 3, 4, 5, 6 CLK TRP: Auto, 3, 4, 5, 6 CLK tRTP: Auto, 2-4, 3-5 CLK TRAS: Auto, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 CLK TRC:Auto, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 , 25 , 26 CLK tWR: Auto, 3, 4, 5, 6 CLK TRRD: Auto, 2, 3, 4, 5 CLK tWTR: Auto, 1, 2, 3 CLK TRFC0: Auto, 75, 10, 127.5, 195, 327.5ns TRFC1: Auto, 75, 10, 127.5, 195, 327.5ns TRFC2: Auto, 75, 10, 127.5, 195,327.5ns TRFC3: Auto, 75, 10, 127.5, 195, 327.5ns
