Introduction

The Intel® Core™2 Extreme quad-core processor QX6000 sequence and Intel® Core™2

quad processor Q6000 sequence are the first desktop quad-core processors that

combine the performance and power efficiencies of four low-power microarchitecture

cores to enable a new level of multi-tasking, multi-media, and gaming experiences.

They are 64-bit processors that maintain compatibility with IA-32 software.

The processors use Flip-Chip Land Grid Array (FC-LGA6) package technology, and plug

into a 775-land surface mount, Land Grid Array (LGA) socket, referred to as the

LGA775 socket. The processors are based on 65 nm process technology.

Note:

In this document the Intel® Core™2 Extreme quad-core processor QX6000 sequence

and Intel® Core™2 quad processor Q6000 sequence are referred to simply as

“processor.”

Note:

In this document the Intel® Core™2 quad-core processor Q6000 sequence refers to the

Intel® Core™2 quad processor Q6600 and Q6700. The Intel® Core™2 Extreme quad-

core processor QX6000 sequence refers to the Intel® Core™2 Extreme quad-core

processors QX6700, QX6800, and QX6850.

The processor supports all the existing Streaming SIMD Extensions 2 (SSE2) and

Streaming SIMD Extensions 3 (SSE3). The processor supports several advanced

technologies including Execute Disable Bit, Intel® 64 architecture, and Intel®

Virtualization Technology (VT).

The processor's front side bus (FSB) uses a split-transaction, deferred reply protocol

like the Intel® Pentium® 4 processor. The FSB uses Source-Synchronous Transfer (SST)

of address and data to improve performance by transferring data four times per bus

clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address

bus can deliver addresses two times per bus clock and is referred to as a "double-

clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus

provide a data bus bandwidth of up to 10.7 GB/s.

The processor uses some of the infrastructure already enabled by the

775_VR_CONFIG_05 platforms including heatsink, heatsink retention mechanism, and

socket. Supported platforms may need to be refreshed to ensure the correct voltage

regulation (VRD11) and PECI support is enabled. Manufacturability is a high priority;

hence, mechanical assembly may be completed from the top of the baseboard and

should not require any special tooling.

The processor includes an address bus power-down capability that removes power from

the address and data signals when the FSB is not in use. This feature is always enabled

on the processor.

1.1

Terminology

A ‘#’ symbol after a signal name refers to an active low signal, indicating a signal is in

the active 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).
