Preface
About This Manual
This manual is written for system integrators, PC technicians and knowledge-
able 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, Hyper Pipelined
Technology, Execution Trace Cache, 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 Technol-
ogy (EM64T). These features allow the motherboard to operate at much higher
speeds with better power management in much safer thermal environments than the
traditional motherboards. The X7DA3+ is ideal for high performance quad processor
or dual processor workstation and enterprise server environments. Refer to our web
site (http://www.supermicro.com/products/) for updates on supported processors.
