Chapter 4: BIOS

No Execute Mode Memory Protection (*Available when supported by the

CPU and the OS.)

Set to Enabled to enable Execute Disable Bit and allow the processor to classify areas in memory where an application code can execute and where it cannot, and thus preventing a worm or a virus from inserting and creating a fl ood of codes to overwhelm the processor or damage the system during an attack.

(*Note: this feature is available when your OS and your CPU support the function

of Execute Disable Bit.) The options are Disabled and Enabled. (Note: For more information regarding hardware/software support for this function, please refer to Intel's and Microsoft's web sites.)

Thermal Management 2 (*Available when supported by the CPU.)

Set to Enabled to use Thermal Management 2 (TM2) which will lower CPU voltage and frequency when the CPU temperature reaches a pre-defi ned overheat threshold. Set to Disabled to use Thermal Manager 1 (TM1), allowing CPU clocking to be regulated via CPU Internal Clock modulation when the CPU temperature reaches the overheat threshold.

Adjacent Cache Line Prefetch (*Available when supported by the CPU.)

The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The CPU fetches both cache lines for 128 bytes as comprised if Enabled. The options are Disabled and Enabled.

Processor Power Management

This feature allows the user to determine the processor power management mode. The options are Disabled and C States Only. If set to Disabled, C States and GV1/GV3 are disabled. If set to C States only, the processor power will be controlled through CPU power states in the APCI setting.

X6DH3-G2, X6DHi-G2 specifications

Super Micro Computer is renowned for its innovation in the server and workstation market, and the X6DH3-G2 and X6DHi-G2 motherboards are prime examples of their commitment to performance, reliability, and advanced technology. These motherboards are designed to cater to the demands of enterprise-level applications, offering robust support for a variety of workloads.

The X6DH3-G2 and X6DHi-G2 motherboards are based on the Intel E7501 chipset, supporting the Intel Xeon processor family. This allows for significant computing power, making them ideal choices for data-centric applications in various fields, from scientific research to database management. One of the standout features of these motherboards is their dual-processor capability, enabling users to harness the power of two Xeon CPUs simultaneously for enhanced multitasking and performance.

In addition to dual-processor support, both motherboards offer up to 64 GB of DDR2 ECC memory. This ensures data integrity and system stability, which are crucial in enterprise environments. The presence of ECC (Error-Correcting Code) memory allows these motherboards to automatically detect and correct data corruption, significantly reducing the risk of system crashes and data loss.

Storage capabilities are another highlight of the X6DH3-G2 and X6DHi-G2 motherboards. They come equipped with multiple SATA and SCSI interfaces, ensuring compatibility with various storage solutions. This flexibility allows users to configure their storage according to their specific needs, whether it be for high-speed access or large-capacity requirements. RAID (Redundant Array of Independent Disks) support is also integrated, enabling users to implement data redundancy and improve performance.

Networking features are robust, with integrated gigabit Ethernet that ensures high-speed connections and efficient data transfer. This is essential for applications demanding low latency and high bandwidth.

The layout of the X6DH3-G2 and X6DHi-G2 motherboards is designed for optimal thermal management and airflow, enhancing system longevity and reliability. They also support a range of expansion slots, including PCI Express, which allows for the addition of graphics cards and other advanced peripherals.

Super Micro’s commitment to quality is evident in these motherboards, showcasing reliability and a wealth of features that make them suitable for demanding enterprise environments. With a focus on performance, scalability, and stability, the X6DH3-G2 and X6DHi-G2 motherboards are engineered to meet the evolving challenges faced by IT professionals and organizations today.
