Thermal Solutions
As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable, long-term system
operation. The overall goal in providing the proper thermal environment is keeping the
processor below its specified maximum case temperature. Heatsinks induce improved
processor heat dissipation through increased surface area and concentrated airflow
from attached fans. In addition, interface materials allow effective transfers of heat
from the processor to the heatsink. For optimum heat transfer, Intel recommends the
use of thermal grease and mounting clips to attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below
for collection of heatsinks evaluated and recommended by Intel for use with Intel
processors.

Example: Using a Pentium

III 866 CPU with front side bus frequency of 133MHz
and PC-133 SDRAM module, the setting of JS3 will be 1-2 and JS4 will
be 2-3. This sets both CPU BUS CLOCK and SDRAM CLOCK to be
133MHz.
For experience user looking for over clocking possibility, please refer to sec 2-3-4.
2-3-3 Install CPU
This motherboard provides a ZIF socket 370. The CPU that comes with the
motherboard should have a cooling FAN attached to prevent overheating. If this is not
the case, then purchase a correct cooling FAN before you turn on your system.

12
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink and CPU cooling FAN is working correctly, otherwise it
may cause the processor and motherboard overheat and damage, you
may install an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the level sideways away from the socket then
upward to a 90-degree angle. Insert the CPU with the correct orientation as shown
below. The notched corner should point toward the end of the level. Because the CPU
has a corner pin for two of the four corners, the CPU will only fit in the orientation as
shown.

When you put the CPU into the ZIF socket. No forces require to insert of the CPU,
then press the level to locate position slightly without any extra force.
2-3-4 Over clock Running
WARNING! This section is for experienced motherboard installer only. Over
clocking can result in system instability or even shortening life of the
processor.
After setting the Jumper JS3, JS4 you can choose over clock running by BIOS CMOS

WARNING! The Design of this motherboard follows chipset and CPU vender’s
design guideline. Any attempts to push beyond product specification
are not recommended and you are taking your own risk to damage
your system or important data. Before over clocking, you must make
sure your components are able to tolerate such abnormal setting,
especially CPU, memory, hard disks, and VGA cards.
2-4 Install Memory
This motherboard provides two 168-pin DUAL INLINE MEMORY MODULES
(DIMM) sites for memory expansion available from minimum memory size of 32MB
to maximum memory size of 512MB SDRAM.

tab should be locked into the DIMM module very firmly and fit into
its indention on both sides.
WARNING! For the SDRAM CLOCK is set at 133MHz, use only PC133-compliant
DIMMs. When this motherboard operate at 133Mhz, most system
will not even boot if non-compliant modules are used because of the
strict timing issues, if your DIMM are not PC133-compliant, set the
SDRAM clock to 100MHz to ensure system stability.

2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively
assign to one use. In a standard design, there are 16 IRQs available but most of them
are already in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 1 System Timer
1 2 Keyboard Controller
2 N/A Programmable Interrupt
3 * 11 Communications Port (COM2)
4 * 12 Communications Port (COM1)
5 * 13 Sound Card (sometimes LPT2)
6 14 Floppy Disk Controller
7 * 15 Printer Port (LPT1)
8 3 System CMOS/Real Time Clock
9 * 4 ACPI Mode when enabled
10 * 5 IRQ Holder for PCI Steering
11 * 6 IRQ Holder for PCI Steering
12 * 7 PS/2 Compatible Mouse Port
13 8 Numeric Data Processor
14 * 9 Primary IDE Channel
15 * 10 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.
2-5-3 Interrupt Request Table For This Motherboard

IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts will
arise between the two PCI groups that will make the system unstable or
cards inoperable.
Note *1 Either AGP slot or onboard VGA can be active at the same time.
2-5-4 AIMM/AGP Slot
In both 615TCF and 615TCS you can plug a 4X AGP VGA Card into the AIMM/AGP
Slot and the 615TCF will disable on board VGA automatically once you plug any
VGA Card into the motherboard. The special function of 615TCF is support AGP
Inline Memory Module in AIMM/AGP Slot. By plug in AGP Inline Memory Module
which with 4MB of 133MHz SDRAM display cache, it will improve on board video
graphic quality. If you are using 615TCF, on board VGA will disabled automatically
once you plug any VGA card into the motherboard.
