Hello. I recently owned a HP Z620. The problem is that everytime I make a change at the hardware, Ex.: Change hard drives, videocard... 942 - Memory Training Error CODE 3016 appears at booting (On CPU0 DIMM1) . I have tried swapping RAM DIMMs but doesnt usually work. Sometimes, reinstalling the firmware works. Thank you and sorry for my bad english.
Edit: When this error appears it doesnt detect either DIMM 1 nor DIMM3 but 8 and 6 are detected (I have 4x4GBs)
