HP Z800 shuts down after 1.5 hours

HP Z800
Other

Hi All,

 

I have 4 machines  (Three Z800s and one Z620) and all demonstate the same behavio, they shut down without warning after runing for about 1.5 hours. No error messages or beep warnings during startup, no beep warnings prior to shutting down. All fans are running interally.  All  systems are running Windows Server 2012 R2.  

 

  • CPU; Intel Zeon E5645 @ 2.4ghz
  • Ram 12GB

I have 4 other Z800s (same configuration) that do not do this.


Thanks for your assistance,

 

Lambert

Compare the bios settings with one of the machines that works oke.

also check driver version and bios version.

 

 

My feeling is that your PSU also needs replacement, but not totally sure about that.

 

Hops it helps.

I generally find that overheating issues will cause my Z620 to shut down or freeze without warning. I would recommend trying CPUID HWMonitor to see if that's the issue.

A quick check of the intel website states a maximum Tcase temperature of 76.2degC for your CPU.

 

Tcase = Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).
