Re: Need help with Reboot cause


excuse delay. personal reasons.

i have been over your readings and they are not far off, but they are not
as close as would like to see. this may be from not being calibrated.

you need to check oem spec for temp ranges for cpus.

drives are warm, but they will be from running.

startx can be a load. dumping sensors will show this.

running a 3 minute sensor dump would be a good way to see just what is
actually happening when running build. using a 1 minute dump would be
better for watching when you know that you are loading down system.

i would be concerned with voltage and temp for cpus. voltages need to be
checked against a dvm and calibrated if off.

getting temps calibrated is a little harder to do. because of this, i would
recommend pulling cpus, cleaning old heat sink paste and applying new. if
old is dry, this will cause a loss of heat transfer. also, you need to insure
that fans are up to speed. check oem for actual speeds.

default high/low temp, voltage, and fan settings should be changed to
proper ranges.

something is wrong here:

> V1.5:        +2.61 V  (min =  +0.00 V, max =  +3.32 V)
v1.5 is high.

fan is slow. can cause cpu to over heat. unless it is a variable speed.

> CPU Temp:    +41.5 C  (low  = -127.0 C, high = +127.0 C)
high, but not excessive. variable speed fan could cause.

these need to be checked against specs.

fans missing?

do you have a manual to tell you what these sensors are for?

indeed they are. manual?

warm, but not a problem. drives do get warm. when they get up in double
digits is when yo need to worry.

a new box will be a wise investment. having a spare would be even wiser.
do you have spare hdd?

not to mention tech support getting old system. :)
