System Overview
T
he Dell
®
OptiPlex
®
Gs and Gs+ systems are high-speed desktop computers.
The Dell
OptiPlex Gs and Gs+ systems are available in two sizes: a low-profile
desktop computer and a midsize desktop computer. Chapters 1 through 3 and
Appendix A contain information that applies to all models of the Dell
OptiPlex
Gs and Gs+ systems. Chapters 4 and 5 provide chassis-specific parts removal
and replacement procedures.
The Dell
OptiPlex Gs and Gs+ systems use the Intel
®
Pentium
®
family of
microprocessors. These Dell computers incorporate the high-performance PCI
expansion bus as well as the ISA expansion bus. These buses are built into the
system board, which also integrates the microprocessor, memory controller,
hard-disk controller, video controller, and other elements of the basic computer.
The microprocessor for the OptiPlex Gs and GS+ systems is installed in a ZIF
socket, which allows the computer to be upgraded when faster microprocessors
become available. Contact Dell for information about Dell-supported micro-
processor upgrades.
The Pentium microprocessor contains a built-in clock multiplier circuit, which
increases the internal operating frequency to a multiple of the system clock
frequency.
The microprocessor operating frequencies for each of these computers are as
follows:
•
Dell OptiPlex Gs and Gs+ 133 systems — 133 MHz derived from a system
clock frequency of 66 MHz
•
Dell OptiPlex Gs and Gs+ 166 systems — 166 MHz derived from a system
clock frequency of 66 MHz
•
Dell OptiPlex Gs and Gs+ 200 systems — 200 MHz derived from a system
clock frequency of 66 MHz
