Product: Hp Z4
Operating System: Microsoft Windows 10 (64-bit)

Hi HP community,

 

At one of our customers that owns approx 100 Z4 workstations Intel(R) Xeon(R) W-2133 CPU @ 3.60GHz with 32GB of memory, 1 workstation is acting up in a really strange way.

 

Intermittently the system will become extremely slow, CPU will be at 100%, a lot of WHEA errors:  component memory, event ID 47 are visible. And latency checks with latencymon shows very large latency  for multiple processes. Obviously a memory module failure, cpu failure, corrupt driver... however the system can come back to total normal operation whenever it wants and function fine for hours even days. That makes troubleshooting a little tricky. 

 

Memory has been reseated and swapped with another workstation. Pci cards reseated but the problem returns. Window defender reports no issues. No other 'virus' like behavior when browsing or using any application observed.

 

Has anybody ever seen this? Could a CPU reseat be a good idea? Reset windows 10 is also an option. But I would like to avoid throwing things at it without being able to determine if they will fix the issue.

 

Thanks
