1-3 HANDLING THE MOTHERBOARD
To avoid damage to your Motherboard, follow these simple rules while
unpacking:
ØBefore handling the Motherboard, ground yourself by grasping an
unpainted portion of the system's metal chassis.
ØRemove the Motherboard from its anti-static packaging. Hold the
Motherboard by the edges and avoid touching its components.
ØCheck the Motherboard for damage. If any chip appears loose, press
carefully to seat it firmly in its socket.
Warning: Do not apply power if the Motherboard appears
damaged. If there is damage to the board, contact your dealer
immediately.
1-4 ELECTROSTATIC DISCHARGE PRECAUTIONS
Make sure to ground yourself before handling the Motherboard or other
system components. Electrostatic discharge can easily damage the
components. Note that you must take special precautions when handling
the Motherboard in dry or air-conditioned environment.
To protect your equipment from electrostatic discharge, take the following
precautions:
ØDo not remove the anti-static packaging until you are ready to install.
ØGround yourself before removing any system component from its
protective anti-static packaging. (To ground yourself, grasp the expansion
slot covers or other unpainted portions of the computer chassis.)
ØFrequently ground yourself while working or use a grounding strap.
ØHandle the Motherboard by its edges and avoid touching its
components.

1-7 MICROPROCESSOR
The motherboard supports a single Slot A processor. The processor’s VID
pins automatically program the voltage regulator on the motherboard to
the required processor voltage. In addition, the front side bus speed (66
MHz and 100 MHz) is automatically selected. The motherboard supports
all (available at time of publication) Slot A processor speeds, voltages, and
bus frequencies.
1-7.1 Microprocessor Packaging
The processor is packaged in a Single Edge Contact Cartridge (SECC or
SECC2) or Single Edge Processor Package (S.E.P.P). The cartridge
includes the processor core, second-level cache subsystem, thermal plate,
and back cover.
The processor connects to the motherboard through the SlotA connector, a
242-pin edge connector. When mounted in SlotA, the processor is secured
by a retention mechanism attached to the motherboard. A passive heatsink
is stabilized by the heatsink supports.
1-7.2 Second Level Cache
The second-level cache is located on the substrate of the CPU package.
The cache includes 512 KB of synchronous pipelined burst static RAM.
All supported onboard memory can be cached.
1-7.3 Microprocessor Upgrades
The motherboard can be upgraded with Slot A processors that run at
higher speeds.

Motherboard Description SY-K7AIA

1-8 MEMORY
1-8.1 Main Memory
The motherboard has four DIMM sockets. SDRAM can be installed in one,
two, three, or four sockets. Using the serial presence detect (SPD) data
structure, programmed into an E²PROM on the DIMM, the BIOS can
determine the SDRAM’s size and speed. Minimum DIMM memory size is
8 MB; maximum DIMM memory size is 256MB. Memory size and speed
can vary between sockets.
The motherboard supports the following memory features:
l168-pin DIMMs with gold-plated contacts
l66/100/133 MHz SDRAM
lNon-ECC (64-bit) and ECC (72-bit) memory
l3.3V memory only
lSupports 8/16/32/64/128/256 MB DIMM Modules
lSupports unbuffered single- or double-sided DIMMs
1-8.2 SDRAM
SDRAM improves memory performance through memory access that is
synchronous with the front-side bus clock. Burst transfer rates at x-1-1-1
timing can be achieved using SDRAM, while asynchronous memory
subsystem are typically limited at x-2-2-2 transfer rates.
Note
All memory components and DIMMs used with the SY-K7AIA
motherboard must comply with the PC SDRAM specifications. These
include: the PC SDRAM Specification (memory component specific), the
PC Unbuffered DIMM Specification, and the PC Serial Presence Detect
Specification.
1-8.3 ECC Memory
ECC memory detects multiple-bit errors and corrects single-bit errors.
When ECC memory is installed, the BIOS supports both ECC and non-
ECC mode. ECC mode is enabled in the Setup program. The BIOS

Motherboard Description SY-K7AIA
11
automatically detects if ECC memory is installed and provides the Setup
option for selecting ECC mode. If any non-ECC memory is installed, the
Setup option for ECC configuration does not appear and ECC operation is
not available.
1-9 CHIPSET
The AMD-K7™processor powers the next generation in computing
platforms, delivering the ultimate performance for cutting-edge
applications and an unprecedented computing experience.
The AMD-750™Chipset is a highly integrated system logic solution that
delivers maximum performance for the AMD-K7 processor and other S2K
