AMD Athlon64 is the hottest CPU these days, as it provides really good & high performance in everything from gaming to Workstation tasks, as compared to Intel CPUs, while still running at a lower clock speed & temperature, it does this by using the AMD Cool & Quite technology, which is something even Intel is also using with their Pentium D & Pentium 4 6xx series CPUs by the name Enhanced Intel Speedstep Technology.
The Cool & Quite technology works by lowering the clock speed, CPU Voltage & CPU Fan speed, when the system is not doing anything heavy & can work even at low clock speed. In case of Athlon64 CPUs, the clock speed is reduced to 800 MHz or 1 GHz & the CPU Core voltage is reduced from 1.5v to 1.4 & in some cases 1.1v (Turian64)
In case U R using an Intel CPU with Intel chipset then EIST is automatically enabled, & works, but in case of AMD, the thing is different, U need to properly configure Cool & Quite to work. For this U will need
1) Athlon64 CPU, as Cool & Quite is not supported on Athlon64 FX CPU & Opetron CPU
2) A Cool & Quite supporting chipset, all of them support this
3) AMD Athlon64 Driver for your operating system
For this example I will be using an Athlon64 3000+ Venice core based CPU, with an Asus A8V-Delux motherboard, stock AMD CPU Fan, & Windows XP SP2
To find which core your CPU is, u can download CPU-Z, it will give U all the info U need about your CPU
But in case U want to find the core, before buying the CPU, then take a look at the numbers written over the CPU when it is still inside the box, un-opened, & look for this numbers
AP = C0 Clawhammer, s754
AR = CG Clawhammer, s754
AS = CG Clawhammer, s939
AX = CG Newcastle, s754
AW = CG Newcastle, s939
BI = D0 Winchester, s939
BP = E3 Venice, s939
BN = E4 San Diego, s939
BU = E5 Newark, s754
LD = E0 Lancaster, s754
BV = E6, Manchester, s939
CD = E6, Toledo, s939
BW = E6, Venice, s939
The difference between BW & BP Venice core is that the BW E6 core runs at a Max 65C & 1.4v insted of 70C & 1.5v E3, in other words, slightly cooler then E3, go for whichever is available, they are both identicle in performance

Athlon64 Quick reference guide
The problem with AMD is that they have many cores for a single rating CPU, like there are 4 varients of Athlon64 3000+, so it's hard to identify
I m assuming that the CPU installation is completed & U are ready to install Windows, before this
1) Go to the BIOS & Load BIOS defaults, now go to the chipset section & Turn on Cool & Quite, & turn on Automatic fan control
2) Now in case U R using a SATA Hard disk, I hardly recommend that U use a Windows XP CD with SP2 slipstreamed, this will make windows recognize the SATA drive & U will not need to install the SATA drivers from the floppy, but even with this, after windows is installed, be sure to install any specific SATA Drivers given with your motherboard for your chipset, the ones included in Windows are only generic
3) Now, after the Windows installation is completed, it’s time to install drivers, follow the series
a. Chipset Drivers given with your motherboard
b. AMD Athlon64 CPU Drivers
c. Graphics Card
d. Sound Card
4) Ones the drivers are installed; it’s time to turn on the Cool & Quite. Right click on your desktop & select properties; go to Screen saver -> Power-> Power Scheme. From the drop down menu select “Minimal Power Management�, then if U want set your monitor to “Never� turn off. Now reboot, & Cool & quite is enabled.
To verify, simply open system properties & check the MHz, it will show that the working Clock speed of your CPU is 800 MHz, U can also use CPU-Z, it will also show that the working clock speed is 800 MHz. Next, simply start something CPU intensive, like a game or 3D Max, or video encoding, your CPU will immediately jump to it’s highest clock speed, in case of over clock, it will jump to the over clocked speed. The CPU Fan speed will also very with this.
Even when it’s running at 800 MHz, the performance is equivalent to a Pentium 4 2 GHz CPU, which is enough for Browsing, Movie watching, Music, infect enough for everything general purpose, as it automatically jump to the maximum clock speed when required
In case U R using nForce chipset by NVIDIA, I strongly suggest u to download & use their nTune system software, it gives u far more control over Cool & Quite & over clocking
In case of any other chipset, U can use the AMD Dashboard, which will give u info regarding your CPU Clock speed, voltage etc

uve to enalbe CnQ in the bios before doing all this..
with CnQ enabled, 71w with it disabled.
