610 systems are high-speed, upgradable workstations
designed around Intel
®
Pentium
®
II Xeon
™
microprocessors with MMX
™
technology. These Dell
®
systems support the high-performance Peripheral
Component Interconnect (PCI) bus and the accelerated graphics port (AGP)
bus. Each system also has an Industry-Standard Architecture (ISA) design with
one ISA slot that allows you to configure the computer system to your initial
requirements and then upgrade it as necessary.
The Pentium II Xeon microprocessor contains a built-in clock multiplier circuit,
which increases the microprocessor’s internal operating frequency to a multi-
ple of the system clock frequency. The microprocessors for Dell Precision 610
mini tower systems operate at a frequency of 400 MHz, derived from a system
clock frequency of 100 MHz.
