ASUS C.O.P. (CPU Overheating Protection)
ASUS C.O.P (CPU Overheating Protection) Technology
is specially designed for ASUS AMD CPU Platform to prevent accidental
cooling malfunction to cause CPU's burning down. Combined with ASUS'
unique Hardware Monitoring mechanism and AMD AthlonXP thermal pins
design, ASUS C.O.P Technology can protect the safety of both AMD
CPU and users' ASUS motherboards better than ever before. When the
CPU's temperature is over the default threshold, a signal will be
sent to automatically shut down the system immediately. Thus the
hardware investment is kept safe and sound. Unlike other ways controlled
by BIOS or software, ASUS C.O.P Technology is more hardware-controlled
and uninterruptible. However, this wonderful feature only works
when users adopt AMD AthlonXP CPU.
How does C.O.P Technology work?
According to AMD AthlonXP's specification, a proper threshold
temperature is set for secure criteria of ASUS models with C.O.P
feature. And this is also the threshold temperature for ASUS C.O.P
Technology to trigger. Under normal condition, CPU fan works great
and the system temperature should keep far beneath the threshold
temperature. However, some accident may happen such as fan failure
or improper fan installation. No matter what factor it is, the temperature
of CPU, because of heat CPU produces, would ramp at fast speed.
On motherboards without C.O.P feature, the only result of this is
that the user finds his computer slowing down, and then hanging
up, and then blacking out and finally CPU in smoke. However, with
C.O.P technology, as the temperature of CPU fluctuates, there will
be a fluctuating voltage difference between specific two pins of
AthlonXP CPU. With this, an ASUS sensor ASIC onboard can get the
approximate temperature and judge if it is over the threshold. As
long as the number reaches the temperature set, the ASUS ASIC will
send a signal out to abort the system by cutting the electricity
supplied to CPU. And then CPU temperature comes down. So, when users
are using ASUS motherboards with C.O.P and find their system abort,
very possible something goes wrong with their fans.
Why by hardware control?
ASUS found that traditional software-controlled method fails to
guarantee the safety of CPU because heat produced may make the operation
of application program and operating system unstable or even in
malfunction. Thus, in the golden time of overheating, software-control
method may fail to stop the system due to out of control. However,
ASUS C.O.P monitors the system via hardware mechanism and it is
more uninterruptible even though the OS or application program hung
than other method does.
What benefit can user get from C.O.P
Of course, the biggest benefit users can enjoy is security of your
computer. You can still keep the healthy CPU and the board. And
all AMD platform motherboards will own this feature to pass the
verification. Actually, users are enjoying the future technology
earlier than other players for six months.
Which asus models provide
Presently, ASUS models including A7M266-D, A7N266
Series, A7V266-EX, A7S333 and A7V333 own this feature. Actually
all ASUS AMD ATX models will finally own this feature.
