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 X7DBT/X7DBT-INF/X7DGT/X7DGT-INF motherboard. The
X7DBT/X7DBT-INF/X7DGT/X7DGT-INF supports dual Intel Xeon 64-bit dual
core/quad core processors at a front side bus speed of 1.333 GHz, 1.066 GHz or
667 MHz. With two Xeon 64-bit dual core processors, the 5000P* or the 5000X **
chipset, and eight DDR2 FBD 667/533 memory modules built-in, the X7DBT/X7DBT-
INF/X7DGT/X7DGT-INF offers substantial functionality and performance enhance-
ments to the motherboards based on the NetBurst dual core microarchitecture
while remaining compatible with the 32-bit based software. Key features supported
include Intel's Extended Memory 64 Technology (EM64T), Hyper-Threading Tech-
nology, Enhanced Intel SpeedStep technology, Virtualization Technology, *PECI
(Platform Environment Control Interface), Advanced Dynamic Execution, Advanced
Transfer Cache, Streaming SIMD Extensions 3 (SSE3), and Thermal Monitor 2
(TM2) Technology. These features allow the motherboard to operate at much higher
speeds with better power management in much safer environments than the tradi-
tional motherboards. The X7DBT/X7DBT-INF/X7DGT/X7DGT-INF is ideal for high
performance dual processor (DP) enterprise server environments. This product is
intended to be professionally installed. (Note:*The X7DBT/X7DBT-INF supports the
5000P Chipset, and **the X7DGT/X7DGT-INF supports the 5000X chipset.)
