Preface Preface About This Manual This manual is written for system integrators, PC technicians, and knowledgeable PC users. It provides information for the installation and use of the X7DA3+ motherboard. The X7DA3+ supports dual Intel Quad-Core and Dual-Core processors with a front side bus speed of 1.333 GHz/1.066 GHz/667 MHz. With two 64-bit Quad-Core and Dual-Core processors built-in, the X7DA3+ offers substantial functionality enhancements to the motherboards based on the Intel Quad-Core/ Dual-Core architecture while remaining compatible with the IA-32 software.
The features include the Intel Virtualization Technology, Thermal Monitor 1/2 (TM1/TM2), Enhanced Intel SpeedStep technology, Advanced Dynamic Execution, Advanced Transfer Cache, Streaming SIMD Extensions 3 (SSE3) and Extended Memory 64 Technology (EM64T). These features allow the motherboard to operate at higher speeds with better power management in safer thermal environments than the traditional motherboards. The X7DA3+ is ideal for high performance quad proces- sor or dual processor workstation and server environments. Refer to our web site (http://www.supermicro.com/products/) for updates on supported processors. This product is intended to be professionally installed.
