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
X7DBU/X7DGU motherboard. The X7DBU/X7DGU supports
dual Intel
XEON 64-bit Quad-core/Dual-core processors at a front side bus speed
of 1.333 GHz/1.066 GHz/667 MHz. With dual 64-bit Xeon Quad-core/Dual-core
processors, the 5000 chipset, and 8 DDR2 FBD 667/533 memory modules built-in,
the X7DBU/X7DGU offers substantial functionality and performance enhancements
to the motherboards based on the Core microarchitecture while remaining compat-
ible with the 32-bit based software. The features include Intel Hyper-Threading
Technology, Virtualization Technology, Hyper Pipelined Technology, Execution Trace
Cache, Thermal Monitor 2 (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 environments than the traditional motherboards. The X7DBU/X7DGU
is ideal for high performance dual processor (DP) enterprise server environments.
This product is intended to be professionally installed.
