Introduction EP-8KTA
Overview
AMD Duron TM & Athlon TM Processors
The AMD Athlon is a seventh-generation micro architecture with an integrated L2 cache, which is powerful enough to support the bandwidth requirements of a large range of applications, hardware, graphics, and memory technologies. These processors implement advanced design techniques such as: w Socket A (PGA 462) w 200MHz system interface based on the Alpha EV6 bus protocol.
w Three out-of-order, superscalar, pipelined Multimedia Units.
w Three out-of-order, superscaler, pipelined Integer Units.
w Fixed-sized internal instruction formats (MacroOPs).
w 72-entry Instruction Control Units.
w AMD enhanced 3DNow! technology w L1 and L2 caches.
w Dynamic branch prediction.
Socket A is the name for AMDs new socketed interface designed to support both
AMD Duron and AMD Athlon processors. This innovation is made possible by integrating the L2 cache memory on chip with the processor. Socket A will help enable smaller enclosures, and ultimately result in a wider variety of solutions in the market.
The AMD Duron & Athlon processors in the Socket A format continue to deliver the ultimate performance for cutting-edge applications. Both bring to desktop systems running industry-standard x86 software superscalar RISC performance.
Being provided in the Socket A format they are the worlds most powerful x86 processors. They easily deliver the highest integer, floating-point, and 3D multimedia performance for applications running on x86 platforms around.
Page 1-2
EP-8KTA Introduction
The AMD Duron processor is derived from the AMD Athlon processor core. It features full-speed, on-chip cache memory, a 200MHz front side system bus, and enhanced 3DNow! technology. Although both processors are related, there are key differences. The AMD Athlon processor is targeted at the performance segment, and as such will have more cache memory and higher clock speeds.
Accelerated Graphics Port
(AGP or A.G.P.)
Typically, 3D graphics rendering requires a tremendous amount of memory, and demands ever increasing throughput speed as well. As 3D products for the personal computer become more and more popular, these demands will only increase. This will cause a rise in costs for both end users and manufacturers.
Lowering these costs as well as improving performance is the primary motivation behind AGP. By providing a massive increase in the bandwidth available between the video card and the processor, it will assist in relieving some of these pressures for quite sometime.
Hardware Monitoring
Hardware monitoring allows you to monitor various aspects of your systems operations and status. The features include CPU temperature, voltage and RPM of fan.
Page 1-3
Introduction EP-8KTA
EP-8KTA Form-Factor
The EP-8KTA is designed with ATX form factor - the new industry standard of chassis. ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a new mounting configuration for the power supply. With these changes the processor is relocated away from the expansion slots, allowing them all to hold full length add-in cards. ATX defines a double height aperture to the rear of the chassis which can be used to host a wide range of onboard I/O. Only the size and position of this aperture is defined, allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output, joystick, modem,
LAN, etc.) to systems. This will help systems integrators differentiate their products in the marketplace, and better meet your needs.
Smaller size promotes a smaller system size.
I/O shield does not need to be retooled in an ATX 2.01 or later. The mainboard should be used in an ATX 2.01 (or later) compliant case.
A smaller power supply can be used. High integration on mainboard reduces the system costs.

Power-On/Off (Remote)
The EP-8KTA has a single 20-pin connector for ATX power supplies. For ATX power supplies that support the Remote On/Off feature, this should be connected to the systems front panel for system Power On/Off button. The systems power
On/Off button should be a momentary button that is normally open.
The EP-8KTA has been designed with Soft Off" functions. You can turn Off the system from one of two sources: The first is the front panel Power On/Off button, and the other is the "Soft Off" function (coming from the EP-8KTAs onboard circuit controller) that can be controlled by the operating system such asWindows ® 95/98 or Windows ® 2000.

System Memory Configuration
Memory Layout
The EP-8KTA supports (3) PC133 168-pin DIMMs (Dual In-line Memory
Module). The DIMMs is for SDRAM (Synchronous DRAM) only.
DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or
125MHz (8ns) bus speed.
If you use both 50ns and 60ns memory you must configure your BIOS to read 60ns.
When using Synchronous DRAM we recommend using the
4 clock variety over the 2 clock.
Figure 2 and Table 1 show several possible memory configurations.
