2-3.1 CPU Installation
Your SY-K7VTA PRO motherboard comes with a CPU retention set kit.
The retention set is used to hold the processor attached to the Socket 462
CPU connector on the motherboard.
FOC ( Fan-Off Control )
The newly designed SOYO “FOC” is based on the concept of total
protection for CPU, which is very different from currently seen on the
market. The H/W control function is used to see a passive security system
of monitoring and warning. “FOC”, designed by SOYO, gives emphasis
on the concept of total protection. S/W Simultaneous Signal Follow-ups
techniques and Auto Power Off System are included to prevent all possible
damage caused by the MAL-functioning of the CPU fan. With the help of
“O/S On Time Monitoring And Warning” function, provided by the H/W
monitoring system, the double-protection purpose is achieved.
“FOC” includes the following functions:
(1) Simultaneous Signal Follow Ups: Before the system enters the O/S,
H/W will detect the signals of the CPU fan pins, get their
revolution information and send it to the BIOS.
(2) Auto Power Off System: If the BIOS gets the information of CPU
fan revolution, it goes on working normally. If not, it will
inform the system and have the power supply disconnected
immediately. Thus, the CPU is protected from over heating.
Note: The following must be observed to secure the normal functioning of
“Fan-Off Control”:
1. CPU fan with sensor pins must be used.
2. CPU fans approved by AMD are strongly recommended.
3. The “HOT KEY” function is provided for the CPU fans without
