X7DB8/X7DBE User's Manual

2-3 Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules.

CAUTION

Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Also note that the memory is interleaved to improve performance (see step 1).

DIMM Installation (See Figure 2-2)

1.Insert the desired number of DIMMs into the memory slots, starting with DIMM #1A. The memory scheme is interleaved so you must install four modules at a time, beginning with DIMM #1A, then DIMM #2A and so on. *For optimal performance, please install four modules at a time up to 8 modules. (*See the Memory Installation Table Below.)

2.Insert each DIMM module vertically into its slot. Pay attention to the notch along the bottom of the module to prevent inserting the DIMM module incorrectly.

3.Gently press down on the DIMM module until it snaps into place in the slot. Repeat for all modules (see step 1 above).

Memory Support

The X7DB8/X7DBE supports up to 16 GB (32 GB) fully buffered (FBD) ECC DDR2 533/667 in 8 DIMMs. Populating DIMM modules with pairs of memory modules of the same size and same type will result in Interleaving Memory which will

increase memory performance.

*Note: Due to OS limitations, some operating systems may not show more than 4

GB of memory.

X7DB8, X7DBE specifications

Super Micro Computer, a global leader in high-performance server and storage solutions, has developed a range of advanced server motherboards, among which the X7DBE and X7DB8 stand out for their robust performance and versatility. Designed for data-intensive applications, these motherboards cater to various markets, including cloud computing, enterprise data centers, and video surveillance.

The X7DBE motherboards are built on the Intel 5000 series chipset and support dual Intel Xeon processors, which provide exceptional processing power for demanding applications. With a maximum memory capacity of 64GB, these motherboards cater to memory-intensive workloads, making them ideal for virtualization and database applications. The X7DBE supports both ECC (Error-Correcting Code) and non-ECC memory, enhancing system reliability and data integrity.

In terms of storage, the X7DBE is equipped with multiple 3.5-inch SATA hard drive bays that allow for substantial data storage capabilities. Additionally, it includes integrated RAID support, enabling users to configure their storage environment for optimal performance and redundancy. The advanced thermal management technology ensures efficient cooling, promoting system stability and longevity even under heavy workloads.

The X7DB8, on the other hand, takes performance a notch higher by providing support for the latest Intel processors and offering enhanced features geared toward high-performance computing. Like the X7DBE, it supports dual processors but extends capability for larger memory configurations, allowing up to 128GB of DDR2 memory. This flexibility makes the X7DB8 an excellent choice for mission-critical applications requiring immense processing power.

Both motherboards come equipped with multiple PCI Express slots, enabling the installation of add-on cards for tasks such as enhanced graphics, additional network interfaces, or dedicated storage controllers, thus providing scalability to meet the growing demands of modern applications. Network connectivity is robust, with several Gigabit Ethernet ports ensuring high-speed data transfer.

In conclusion, Super Micro's X7DBE and X7DB8 motherboards exemplify the perfect blend of performance, scalability, and reliability. With their support for advanced technologies and their ability to handle high workloads, they are ideal solutions for businesses seeking to optimize their server infrastructure. As technology continues to evolve, these motherboards remain pertinent, providing a solid foundation for various applications and future advancements.
