64-bit versions of Windows are for computer users who have high-performance needs and are typically running a computer with 4 GB or more of random access memory.
Put simply, a 64-bit PC can handle larger amounts of information than a 32-bit system. Since it can use more RAM—4 GB and up—a 64-bit computer can be more responsive when you're running lots of programs at once.
Both 32-bit and 64-bit installation discs are included in the Windows 7 retail box.
Most 64-bit operating systems can handle large amounts of memory—typically 4 gigabytes (GB) of random access memory (RAM) or more—more efficiently than 32-bit operating systems. However, not all computers are 64-bit capable.
All packaged retail editions of Windows 7 (except for Home Basic) include both 32- and 64-bit software.

FSB, Memory Bus, DDR, Dual Channel
Source
My FSB is 200 MHz (my motherboard support 800 MHz)...
And my bus speed is 800 MHz!
What is the difference here?
Why only 200 MHz when I check it?
Specs for the CPU:
Intel Pentium4 2.6 GHz / Hyper Threading
Core: Northwood
Frequency: 2.6GHz
FSB: 800MHz
Cache: L1 12KB+8KB; L2 512KB
Specs for the Mobo:
Model: 865PE Neo2-LS
Supported CPU: Socket 478 Pentium 4 Processors(Hyper-Threading)
Chipset: Intel 865PE + ICH5
FSB: 800/533/400MHz
RAM: 4x DIMM support Dual Channel DDR 400/333/266 Max 4GB
Answer:
You are using DDR PC 3200 memory, also called 400 Mhz DDR
The memory bus [from memory to the MCH chip] runs at 200 MHz.
HOWEVER DDR (Double Data Rate) makes TWO reads|writes per clock cycle, once on the leading edge and once on the trailing edge, thus 2 X 200 = 400.
Then Dual Channel does the rest.
The mobo/chipset actually has TWO memory busses from the memory to the MCH chip.
The MCH stages these two memory busses to the CPU such that the CPU is getting FOUR read/writes per clock cycle.
Thus 2 X 400 = 800.
Of course you must have two memory sticks of same size et al, one in the even slot and one in the odd slot so that both memory busses are being fed from memory.

MCH [formerly Northbridge] is Memory Controller Hub
ICH [formerly Southbridge] is I/O Controller Hub.
Substantially improved from original NorthBridge and SouthBridge.
The interface between the ICH and MCH is far faster than what existed in the NB/SB interface. Those chipsets were designed to remove as many readblocks as possible for all types of data transfers.
BTW the AMD 64 bit CPU's have the MCH on the CPU chip.
The lower priced AMD MCH does NOT handle Dual Channel, only the higher priced version has a builtin MCH that handles Dual Channel.

Peripheral Component Interconnect
On a PC, there is a limited number of hardware interrupts (IRQs), and the PCI bus is designed to share them. Thus, on a PCI-only PC, there is never an IRQ conflict as there was on earlier machines that used the ISA bus.
ISA cards required an assigned IRQ that was fixed to that peripheral device.
PCs with both ISA and PCI buses were made for several years. If there was only one IRQ remaining after the rest were reserved for ISA cards, all PCI devices could share it.
In such a dual bus PC, all reserved IRQs are registered in the PC's BIOS setup. On startup, PCI reads the setup memory and configures all PCI cards automatically.
For a comparison of PCI technologies, see PCI-SIG.
See PCI Express, PCI-X, Concurrent PCI, CompactPCI, PXI, Mini PCI, PC data buses, PICMG and Sebring ring.
Peripheral Component Interconnect
The most widely used I/O bus (peripheral bus).
It provides a shared data path between the CPU and peripheral controllers, such as network, display, SCSI and RAID cards.
Designed by Intel, Compaq and Digital, the PCI bus first appeared in PCs in 1993 and co-existed with the ISA bus for many years.
Today, most computers have only PCI slots along with one AGP or one PCI Express slot for the display adapter.
PCI Slots
PCI runs at 33 MHz or 66 MHz and supports 32 and 64-bit data paths and bus mastering.
There are generally three or four slots on the motherboard, and the quantity is based on 10 electrical loads that deal with inductance and capacitance.
The PCI chipset uses three, leaving seven for peripheral controllers.
A controller on the motherboard uses one load; a plug-in card uses 1.5 loads.
A "PCI bridge" connects PCI buses together for more slots.

PCI-X (PCI eXtended)
An enhanced PCI bus technology originally developed by IBM, HP and Compaq that is backward compatible with existing PCI cards. PCI and 32-bit PCI-X slots are physically the same, and PCI cards can plug into PCI-X slots. PCI-X cards will run in PCI slots, but at the slower PCI rates. The 64-bit PCI-X slots are longer.
First introduced in 1999, PCI-X offered increased speed over PCI and has steadily increased to more than 30 times that of the original PCI bus.
First introduced in 1999, PCI-X offered increased speed over PCI and has steadily increased to more than 30 times that of the original PCI bus.
Do not confuse PCI-X with PCX, which is the abbreviation of PCI Express.
PCX (PCI Express)
A high-speed peripheral interconnect from Intel introduced in 2002. Note that although sometimes abbreviated "PCX," PCI Express is not the same as "PCI-X" (see PCI-SIG and PCI-X for comparison). As a result of the confusion, "PCI-E" or "PCIe" is the accepted abbreviation.
Initially used for high-speed display adapters, and intending to eventually replace the PCI and AGP buses entirely, PCI Express was designed to match the higher speeds of today's CPUs. It can accommodate Gigabit and 10 Gigabit Ethernet and even support chip-to-chip transfers.
Switched Architecture
Rather than the shared, parallel bus structure of PCI, PCI Express provides a switched architecture using serial communications channels, each made up of two differential wire pairs that provide 2.5 Gbits/sec in both directions. Up to 32 channels ("lanes") may be combined in x2, x4, x8, x16 and x32 configurations, creating a parallel interface of independently controlled channels. The bandwidth of the switch backplane determines the total capacity of a PCI Express implementation.
Internal in 2002, External in 2007
Similar in architecture to InfiniBand, PCI Express was initially designed for internal connections, whereas InfiniBand provides a true fabric architecture for external networks. However, enhancements that extended PCI Express outside of the box for several meters were developed in 2007. External PCI Express allows, for example, a laptop computer to hook up to an external display adapter and monitor, providing greater performance than the laptop's internal display adapter.
Different Slots
Originally called "Third Generation I/O" (3GIO), PCI Express is software compatible with PCI, but not plug compatible. It also uses slots of different lengths because of the combined lanes (see below). See ExpressCard and PCI-X.

PAT
Source (excerpts)
A block diagram of the 875P chipset — Source: Intel
PAT stands for Performance Acceleration Technology used in certain Intel chipsets as 875P MCH chip.
What Intel is doing, in fact, is "binning" its chips, just like it does its processors.
In all likelihood, the 875P silicon will come from the same wafers and essentially be the same chips as Intel's upcoming Springdale chipset, but Springdale will be a cheaper, higher-volume product. (Springdale chipsets will differ from the 875P only in that they won't include PAT or support for ECC memory types.)
The 875P will cost a little more, and will be aimed at workstation users and enthusiasts.
Intel probably plans to pick the very fastest Canterwood/Springdale MCH (north bridge) chips and test them to verify they're capable of running with PAT enabled.
The best of those chips will be sold as 875P MCH chips.
With PAT enabled, the 875P memory controller will perform some internal memory handling tasks faster, yielding a one-clock improvement in the time for a CPU request to perform memory access and another one-clock improvement in the DRAM chip select process.

The total improvement is two clocks for each chip select (CS) process. CS happens at the beginning of a typical memory access, so cutting the CS process by two cycles could lead to real-world reductions in memory access latency.
Intel emphasizes that 875P chipsets are tested rigorously, at full operating speed, for their ability to run with PAT enabled, so Canterwood motherboards ought to be plenty stable under normal operating conditions. Intel is also quick to point out that PAT happens internally in the memory controller, while external memory interfaces run according to their specifications.
