A7V333 improper cpu setting & shutdown/restart problems

[Jared]

Here is a rundown of my problem. Several months ago my computer would
ocassionally power off or reboot, and when restarting it would say it
found a hardware error and take me into the hardware monitor in the
BIOS and it would show the CPU has being overheated. When it would
just shutdown, i would try to restart the computer...I would get a
short burst of the HD and then powerdown again. I would have to wait
10-30 minutes before the computer would boot up again (taking me into
the BIOS saying the computer had hung due to an improper cpu
speed...).
Then started using Asus probe to monitor the problem...and I found
that my cpu fan was crapping out on me and that was causing my cpu to
overheat. I would use my computer until the fan would drop to very
low rpms and cause the cpu to overheat. I may only be able to use my
computer for 30 minutes or up to 2 hours...until i would have to
manually shut down the computer.

Well, just recently I replaced the heatsink/fan. I monitored the
temperature and it was around 50-55C...and staying steady. But now I
still have problems with the computer just shutting down...but the
temperatures are still in acceptable ranges. I have however noticed
that the rpm's of my power supply fan have ocassionally slightly
dropping below the acceptable range (but this is probably
coincidental...since it only just started now).

I've searched the newsgroup for some guidance but haven't found much.
I've seen others with similar problems but nothing to really explain
or help fix the problem. I've seen someone talk about possible
jp1/jp2 jumper settings for the RAM voltage.

If anyone has any idea what the problem could be, or how to help
troubleshoot this, i would be grateful!

not really got a clue, but you do not state what your case temperatures are,
or if the cpu temperature is diode or socket (a7v333 reads both) it may
still be heat related, especially if you have no extractor case fans. The
temperature does seem very high (even for diode readings) but it depends
where in the world you are and what your ambient temperatures are you do not
state if it still will not restart after it shuts down - if so it would
suggest the problem is heat again. Have you checked the heatsink is on
correctly and that you are using some sort of heat transfer compound

then again it may be power related.

Not sure if j1 & j2 would have much effect but could try setting them away
from the default setting which is jp1 - the 2 pins furthest from cpu and
jp2 - the 2 pins nearest the cpu. This gives the default voltage for the
board of 2.78 - 2.85v - which is overvolted compared to most systems. The
opposite of this layout is 2.88-2.96v which is too high. Both jumpers on
the 2 pins furthest from the cpu is a normal non overvolted range for a
computer and the 2 pins nearest the cpu is stupidly high (over 3v) and will
not do the ram any good at all.

I have an overclocked cpu (by 600mhz) in my a7v333 and if the power goes off
suddenly (eg I have not fed the electric meter) the machine complains about
the overclocked cpu and takes me into the bios (and I just exit the bios and
the system boots) otherwise it is fine.

Unless your computer is in a 100 degree garage then your running hot if
those temps are at idle with nothing running but Windows. When you replaced
the HSF did you use thermal grease,or did the unit come with a thermal pad?
There is a piece of tape covering those thermal pads.

I just built a new comp for my daughter using a A7V266-E and XP2000. I cool
the thing with a Zalman 6000 HS and fan. At idle the highest temp I saw was
44-45C. This is at idle with the sides of the case on. If I adjusted the
speed down into the 1300-1400 range the temps would creep into the 47-48C
range.

Try running the comp for a couple of hours with the side off and a fan
blowing directly over the heatsink. With no shutdown or reboot you've got a
heating problem. If your HSF is running below the acceptable range then its
down in the 1300 RPM range,thats pretty slow unless you have a huge fan.
Also,is your power supply new or in good shape? Those can also overheat and
cause shutdowns or reboots.

I'd say the ambient temperature for the room is around 75F(24C), give
or take a few degrees. Yes, when I replaced the HSF it came with a
silicon compound that I used.

Try running the comp for a couple of hours with the side off and a fan
blowing directly over the heatsink. With no shutdown or reboot you've got a
heating problem.

I took a floor fan and put it next to the open case and had the comp
running at idle. The cpu temp was getting up to 136F (58C) and the MB
temp was pushing 90F (32C). I'd say after 20 minutes the comp shut
down. Earlier today, (with no floor fan next to case)...it went at
about same temperatures but was on for about an hour until shutdown.
And last evening...the computer was on for about 6 hours with no
shutdown (getting up to the same temperatures). However, after 6
hours I attempted to manually restart the computer...and when doing
so, it took me right into the BIOS saying the "improper cpu speed"
message. Today, on both ocassions, when the computer shutdown, and
finally able to startup 15-30 minutes later...it didn't go into the
BIOS giving me that message.

If your HSF is running below the acceptable range then its
down in the 1300 RPM range,thats pretty slow unless you have a huge fan.
Also,is your power supply new or in good shape? Those can also overheat and

Well, the power supply was new when i got the computer new 1 1/2 years
ago. Not sure on the shape of the PSU though. I have noticed that in
the past couple of weeks, the rpms of the PSU fan has been dropping to
around 1500-1600 when I think it normally runs at about 2200-2400.

I have no idea if the temp is diode or socket. Not sure what that is.
And in addition to the cpu fan, i have 3 case fans. One in the front,
and 2 in the back.

The
temperature does seem very high (even for diode readings) but it depends
where in the world you are and what your ambient temperatures are you do not
state if it still will not restart after it shuts down - if so it would

Yeah, i used a silicon compound when replacing the HSF and as far as I
know its on correctly.

Not sure if j1 & j2 would have much effect but could try setting them away
from the default setting which is jp1 - the 2 pins furthest from cpu and
jp2 - the 2 pins nearest the cpu. This gives the default voltage for the

the 2 pins furthest from the cpu is a normal non overvolted range for a
computer and the 2 pins nearest the cpu is stupidly high (over 3v) and will
not do the ram any good at all.

Well, i might try changing the jumpers to a normal non-overvolted
range and see if that does anything. would setting of these jumpers
have any affect on the temp of the MB? Because at this point i'm
still thinking its a heating and/or PSU problem.
