Introduction

Terminology

A '#' symbol after a signal name refers to an active low signal, indicating a signal is in
the asserted state when driven to a low level. For example, when RESET# is low, a
reset has been requested. Conversely, when NMI is high, a nonmaskable interrupt has
occurred. In the case of signals where the name does not imply an active state but
describes part of a binary sequence (such as address or data), the '#' symbol implies
that the signal is inverted. For example, D[3:0] = 'HLHL' refers to a hex 'A', and
D[3:0]# = 'LHLH' also refers to a hex 'A' (H= High logic level, L= Low logic level).
Commonly used terms are explained here for clarification:
• Quad-Core Intel® Xeon® Processor 5300 Series – Intel 64-bit microprocessor
intended for dual processor servers and workstations. The Quad-Core Intel®
Xeon® Processor 5300 Series is based on Intel's 65 nanometer process, in the
FC-LGA6 package with four processor cores. For this document, "processor" is used
as the generic term for the "Quad-Core Intel® Xeon® Processor 5300 Series". The
term 'processors' and "Quad-Core Intel® Xeon® Processor 5300 Series" are
inclusive of Quad-Core Intel® Xeon® Processor E5300 Series and Quad-Core
Intel® Xeon® Processor X5300 Series.
• Quad-Core Intel® Xeon® Processor E5300 Series – A mainstream
performance version of the Quad-Core Intel® Xeon® Processor E5300 Series. For
this document "Quad-Core Intel® Xeon® Processor E5300 Series" is used to call
out specifications that are unique to the Quad-Core Intel® Xeon® Processor E5300
Series SKU.
• Quad-Core Intel® Xeon® Processor X5300 Series – An accelerated
performance version of the Quad-Core Intel® Xeon® Processor X5300 Series. For
this document "Quad-Core Intel® Xeon® Processor X5300 Series" is used to call
out specifications that are unique to the Quad-Core Intel® Xeon® Processor X5300
Series SKU.
• FC-LGA6 (Flip Chip Land Grid Array) Package – The Quad-Core Intel® Xeon®
Processor 5300 Series package is a Land Grid Array, consisting of a processor core
mounted on a pinless substrate with 771 lands, and includes an integrated heat
spreader (IHS).
• LGA771 socket – The Quad-Core Intel® Xeon® Processor 5300 Series interfaces
to the baseboard through this surface mount, 771 Land socket. See the LGA771
Socket Design Guidelines for details regarding this socket.
• Processor core – Processor core with integrated L1 cache. L2 cache and system
bus interface are shared between the two cores on the die. All AC timing and signal
integrity specifications are at the pads of the processor die.
• FSB (Front Side Bus) – The electrical interface that connects the processor to the
chipset. Also referred to as the processor system bus or the system bus. All
memory and I/O transactions as well as interrupt messages pass between the
processor and chipset over the FSB.
