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 X7DA8/X7DAE motherboard. The X7DA8/X7DAE supports dual Intel quad core/dual core processors with an FSB speed of 667 MHz/1.066 GHz/1.333 GHz. With dual 64-bit quad core/dual core processors built-in, this moth- erboard offers substantial functionality enhancements to the motherboards based on the Intel Core microarchitecture while remaining compatible with the IA-32 software.

The features include Intel Hyper-Threading Technology, 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 much higher speeds with better power management in much safer thermal environments than the traditional motherboards. The X7DA8/ X7DAE is ideal for high performance dual processor (DP) workstation and enterprise server environments.

Please refer to the motherboard speciﬁ cations pages on our web site (http://www.supermicro.com/products/motherboard) for updates on sup- ported processors. This product is intended to be professionally installed. Manual Organization Chapter 1 describes the features, speciﬁ cations and performance of the mainboard and provides detailed information about the chipset. Chapter 2 provides hardware installation instructions. Read this chapter when in- stalling the processor, memory modules and other hardware components into the system. If you encounter any problems, see Chapter 3 , which describes trouble- shooting procedures for video, memory and system setup stored in the CMOS.

Chapter 4 includes an introduction to the BIOS and provides detailed information on running the CMOS Setup utility. Appendix A and Appendix B provide BIOS POST Messages and POST Codes. Appendix C, Appendix D and Appendix E list HostRAID Setup Guidelines and Software Installation Instructions. Conventions Used in the Manual: Special attention should be given to the following symbols for proper installation and to prevent damage done to the components or injury to yourself: Danger/Caution: Instructions to be strictly followed to prevent catastrophic system failure or to avoid bodily injury. Warning:
