5. Setting CPU Voltage & Frequency
3. Installing Processor
4. Supported CPU Type
Note:
If you do not match the CPU
socket Pin 1 and CPU cut edge
well, it may damage the CPU.
CPU socket lever
CPU Pin 1 and cut edge
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.
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. It is not necessary to set CPU Core Voltage
Setting CPU Frequency
This motherboard is CPU jumper-less design, the system can detect the CPU frequency
automatically, and no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio
Warning:
We strongly
recommend you do
not overclocking your
CPU and system for
get more system
reliability.
Fortress1100 supports one Coppermine (up to 1 GHz with 256 L2 cache) or Tualatin
(up to 1.26 GHz with 512K L2 cache) processor with external FSB up to 133 MHz.
