CHAPTER 2: HARDWARE INSTALLATION
2.1INSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Remove the socket protection cap.
Step 2: Pull the lever toward direction A from the socket and then raise the lever up to a 90-degree angle.
Step 3: Look for the white triangle on socket, and the gold triangle on CPU should point forwards this white triangle. The CPU will fit only in the correct orientation.
7
Motherboard Manual 
Step 4: Hold the CPU down firmly, and then close the lever toward direct B to complete the installation.
Step 5: Put the CPU Fan on the CPU and buckle it. Connect the CPU FAN power cable to the JCFAN1. This completes the installation.

Memory voltage Overclocking.
1.When “JDDRII_2.4V” jumper cap is placed on Pin 1-2, memory voltage can be manually adjusted under CMOS setup.
2.When “JDDRII_2.4V” jumper cap is placed on Pin 2-3, memory voltage will be fixed at 2.4V automatically, and can’t be adjusted under COMS setup.
Before setting memory voltage overclocking, please ensure that your DDR II supports up to 2.4V. (Consulting your DDR2 memory module supplier)

CHAPTER 4: NVIDIA RAID FUNCTIONS
4.1 |
OPERATION SYSTEM |
z Supports Windows XP Home/Professional Edition, and Windows 2000 Professional. |
|
4.2 |
RAID ARRAYS |
NVRAID supports the following types of RAID arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for many applications.
RAID 1: RAID 1 defines techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1.
4.3HOW RAID WORKS
RAID 0:
The controller “stripes” data across multiple drives in a RAID 0 array system. It breaks up a large file into smaller blocks and performs disk reads and writes across multiple drives in parallel. The size of each block is determined by the stripe size parameter, which you set during the creation of the RAID set based on the system environment. This technique reduces overall disk access time and offers high bandwidth.
Features and Benefits
Drives: Minimum 1, and maximum is up to 6 or 8. Depending on the platform.
Uses: Intended for non-critical data requiring high data throughput, or any environment that does not require fault tolerance.
Benefits: provides increased data throughput, especially for large files. No capacity loss penalty for parity.
Drawbacks: Does not deliver any fault tolerance. If any drive in the array fails, all data is lost.
Fault Tolerance: No.

Motherboard Manual 
RAID 1:
Every read and write is actually carried out in parallel across 2 disk drives in a RAID 1 array system. The mirrored (backup) copy of the data can reside on the same disk or on a second redundant drive in the array. RAID 1 provides a hot-standby copy of data if the active volume or drive is corrupted or becomes unavailable because of a hardware failure.
RAID techniques can be applied for high-availability solutions, or as a form of automatic backup that eliminates tedious manual backups to more expensive and less reliable media.
Features and Benefits
Drives: Minimum 2, and maximum is 2.
Uses: RAID 1 is ideal for small databases or any other application that requires fault tolerance and minimal capacity.
Benefits: Provides 100% data redundancy. Should one drive fail, the controller switches to the other drive.
Drawbacks: Requires 2 drives for the storage space of one drive. Performance is impaired during drive rebuilds.
Fault Tolerance: Yes.

RAID 0+1:
RAID 0 drives can be mirrored using RAID 1 techniques. Resulting in a RAID 0+1 solution for improved performance plus resiliency.
Features and Benefits
-Drives: Minimum 4, and maximum is 6 or 8, depending on the platform.
-Benefits: Optimizes for both fault tolerance and performance, allowing for automatic redundancy. May be simultaneously used with other RAID levels in an array, and allows for spare disks.
-Drawbacks: Requires twice the available disk space for data redundancy, the same as RAID level 1.
-Fault Tolerance: Yes.

CHAPTER 5: OVERCLOCK QUICK GUIDE
5.1T-POWER INTRODUCTION
Biostar T-Power is a whole new utility that is designed for overclock users. Based on many precise tests, Biostar Engineering Team (BET) has developed this ultimate overclock engine to raise system performance. No matter whether under BIOS or Windows interface, T-Power is able to present the best system state according to users’ overclock setting.
T-Power BIOS Features:
Overclocking Navigator Engine (O.N.E.)
CMOS Reloading Program (C.R.P.)
Memory Integration Test (M.I.T., under Overclock Navigator Engine)
Integrated Flash Program (I.F.P.)
Smart Fan Function (under PC Health Status)
Self Recovery System (S.R.S)
T-Power Windows Feature:
Hardware Monitor
Overclock Engine
Smart Fan Function Life Update

5.2T-POWER BIOS FEATURE
A. Overclocking Navigator Engine (O.N.E.):
ONE provides two powerful overclocking engines: MOS and AOS for both Elite and Casual overclockers.
Manual Overclock System (M.O.S.)
MOS is designed for experienced overclock users.
It allows users to customize personal overclock settings.

Motherboard Manual 
CPU Overclock Setting:
CPU Voltage:
This function will increase CPU stability when overclocking. However, the CPU temperature will increase when CPU voltage is increased.
Choices: The adjustable range is from 0.800V to 2.310V.
CPU Frequency:
CPU Frequency is directly in proportion to system performance. To maintain the system stability, CPU voltage needs to be increased also when raising CPU frequency.
Choices: This range is from 200 to 450, with an interval of 1MHz.
Memory Overclock Setting:
Memory Voltage:
This function will increase memory stability when overclocking. Choices: The range is from 1.80V to 2.1V, with an interval of 0.05V.
Memclock Frequency:
To get better system performance, sometimes downgrading the memory frequency is necessary when CPU frequency is adjusted over the upper limit.
Choices: DDR2 400, DDR2 533, DDR2 667, DDR2 800 (MHz).
PCI-Express Overclock Setting:
PCIE Clock:
It helps to increase VGA card performance.
Choices: The range is from 100 to 145, with an interval of 1MHz.
Chipset Overclock Setting:
NB/SB Voltage Regulator:
This function will increase chipset stability when overclocking. Choices: 1.52V, 1.60V, 1.68V, 1.76V.
HT Frequency:
We recommend users to set this item at “x4” when overclocking. Choices: x1, x2, x3, x4, x5, Auto.
