hello, I 've checked the Event Viewer on Windows 7 Filtering for id 20,47
for all the registers, no errors found for ID 47 and ID 20 only for other causes and until 04/11/2016,
I also tried swapping the ram on more slots, but it does not work, the error is always given on "DIMM 3 oN CPU1", but in this slot I tried 3, 4 different memory bank.
so, the warranty hp definitely is ended but the ebay vendor warranty is one year and are still in the period of "withdrawal from purchase" I have to know if the defect is severe and then return the workstation to the supplier or request a replacement.
Have a nice day :-)
