Z440 Workstation - compatible with E5-2667 v3 3.2GHz processor?

[DMP3]

HI, I'm troubleshooting a refurbished z440, which came specced with an Intel E5-2667 v3 3.2GHz processor.

The machine has an intermittent crashing issue, where either the screen locks up, it pings up a white-screen message, or it just spontaneously reboots. Can vary from being fine for weeks, to dying 3 times in 10 minutes. I've  nowgot it running through a UPS, as I'd thought it was a mains electric issue (rural location), but it still seems to recur.

I was looking through some HP documentation, and I can't find a single source that says this processor is compatible with this machine. Can someone verify whether this is a compatible processor for the Z440, or whether it might actually be the cause of the issue?

thanks,

Dave

DMP3,

There are 584, z440's tested with 4 results in Passmark baselines for Z440 / E5-2667 v3 systems with system ratings of:  6041, 5337, 4683, and 4484 and with quite consistent CPU marks between 16036 to 16247. This is not a large proportion of Z440's, but does demonstrate that it's possible. The best performing 8-core on the Z440 is the Xeon E5-1680 v3 with a CPU mark of 17400. 

The inconsistency of the failures is difficult to understand without knowing more about the system configuration, OS, BIOS version, and etc.  In general, a place to start so as to eliminate possible causes might be to:

1.  update all the drivers including chipset, controllers, GPU, and etc,

2.  try running with only one RAM module, and possibly start the system on each module to test for a bad one, 3.  (carefully) flash the latest BIOS,

4.  format the drive, verifying the partitions are  GPT, then reload the OS, and

5.   try an fairly recent- Maxwell or Pascal, alternative GPU.
