1.
Pull up the CPU socket lever and up to
90-degree angle.
2.
Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU upper interface.
Match Pin 1 and cut edge. Then insert the
CPU into the socket.
3.
Press down the CPU socket lever and finish
CPU installation.

This jumper is used to activate either the EEPROM chipset on CNR card or the onboard
EEPROM chipset. With onboard LAN equipped on this motherboard, you may short pins
1-2 to enable the onboard EEPROM for running onboard LAN. However, if you were to
use CNR card to run LAN, you may short pins 2-3 to disable the onboard EEPROM
chipset.
5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.05V to 1.825V.
Setting CPU Frequency
CPU frequency can be set through the BIOS setup.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setting
Core Frequency = CPU FSB Clock * CPU Ratio

3. Installing CPU
Note:
If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.

815E B-Step /
815EP B-Step chipset supports
maximum 133MHz FSB and
66MHz AGP clock, higher clock
setting may cause serious
system damage.
Warning:
To avoid possible CPU damage caused by overheating, an automatic
shutdown of system had been especially designed on this motherboard. System
would be automatically power off when this motherboard with implementation of
THERMTRIP circuit detected a CPU temperature above 135 degree for 4 seconds.
