Frequently Asked Questions - TA75A+ BIOSTAR

How do I install the CPU on the Biostar TA75A+?

First, lift the socket lever fully. Align the gold triangle on the CPU with the triangle on the socket, gently place the CPU, then close the lever. Ensure the CPU is seated correctly before applying thermal paste and attaching the cooler.

How can I update the BIOS on this motherboard?

Download the latest BIOS from the Biostar website. You can update through the BIOS utility 'BIOS Update' or by using a DOS bootable USB. Follow the instructions carefully to avoid bricking the board.

What type of RAM is compatible with the TA75A+?

It supports DDR3 memory, 1.5V, unregistered, non-ECC. Maximum capacity is 16 GB across two slots. Speeds up to 1866 MHz (overclocked) are supported with compatible APUs.

Does the TA75A+ support CrossFire or dual graphics?

It does not support CrossFire because it has only one PCIe x16 slot. However, it supports Dual Graphics when using an AMD A-series APU with a compatible discrete Radeon GPU.

How do I clear the CMOS on the TA75A+?

You can clear CMOS by removing the CMOS battery (CR2032) for a few minutes, or by moving the CMOS jumper (JBAT1) to the clear position for 5 seconds, then moving it back.

What is the maximum CPU power (TDP) supported?

The TA75A+ supports AMD A-series APUs with a maximum TDP of 100W. Processors with higher TDP may not be compatible or may cause overheating.

How can I set up RAID on this motherboard?

Enter the BIOS setup and go to the 'Advanced' tab. Set the SATA mode to RAID. Save and reboot, then press Ctrl+F to enter the RAID configuration utility to create arrays.

Why is there no display output after powering on?

Check that the CPU power connector (4+4 pin) is plugged in, RAM is properly seated, and if using a discrete GPU, the monitor is connected to the GPU, not the motherboard. Also try clearing CMOS.

Can I use Windows 10 on the Biostar TA75A+?

Official driver support is for Windows 7 and 8. However, many users have reported successful operation with Windows 10 using default drivers or those from Windows Update. Some features may not work.

How do I connect the front panel audio header?

Consult the manual for the exact pin layout. Typically, the header supports HD Audio (default) or AC'97. Ensure the audio cable from your case matches the pinout; misalignment may cause no sound.

CHAPTER 5: RAID FUNCTIONS

Supports Windows Vista and Windows 7.

5.2 RAID ARRAYS

RAID 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 10: RAID 10 combines the techniques used in RAID 0 and RAID 1.

5.3 How 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 2, 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.

graph TD
    A["A75"] --> B["Block 1\nBlock 3\nBlock 5"]
    A --> C["Block 2\nBlock 4\nBlock 6"]

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.

    A --> C["Block 2"]
    A --> D["Block 3"]
    B --> E["=="]
    C --> E
    D --> E

RAID 10:

RAID 1 drives can be stripped using RAID 0 techniques. Resulting in a RAID 10 solution for improved resiliency, performance and rebuild performance.

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.

BIO-Flasher: Update UEFI BIOS file from USB Flash Drive

!! WARNING !!

For better system performance, the UEFI BIOS firmware is being continuously updated. The UEFI BIOS information described below in this manual is for your reference only and the actual UEFI BIOS information and settings on board may be different from this manual. For further information of setting up the UEFI BIOS, please refer to the UEFI BIOS Manual in the Setup CD.

A. Overclocking Navigator Engine (O.N.E.)

O.N.E provides 4 systems allowing users to customize personal overclock settings: Manual Voltage System, Manual Memory System, Manual MCT System, and Manual G.P.U System.

Notice:
Not all types of Intel CPU perform above overclock setting ideally; the difference will be based on the selected CPU model.

NOTE

Overclock 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.

B. Self Recovery System (S.R.S.)

This function can't be seen under UEFI BIOS setup, and is always on whenever the system starts up.

However, it can prevent system hang-up due to inappropriate overclock actions.

When the system hangs up, S.R.S. will automatically log in the default UEFI BIOS setting, and all overclock settings will be re-configured.

C. Smart Fan Function

Smart Fan Function is under "Smart Fan Control" in "Advanced Menu".

This is a brilliant feature to control CPU/System Temperature vs. Fan speed. When enabling Smart Fan function, Fan speed is controlled automatically by CPU/System temperature.

This function will protect CPU/System from overheat problem and maintain the system temperature at a safe level.
