Good night

Someone with this problem xom workation 620 - 929 - Fatal MCA error. QPI0 error detected CPU0, already updated firmware "Management Engine Firmware # and bios and sometimes this message appears can someone help please

[DGroves]

you have a memory related error on CPU 0, most likely a ram module is failing/has failed or a bad module connection try reseating the ram, and then run a memory test like "memtest 86+"  (the "+"plus is important) google for a DL site

Miguel, try as DGroves said.  It is a loose connection :  motherboard X riser-board    either   ram memories X riser-board .

DO NOT TOUCH WHILE  UNDER VOLTAGE !

After disconnect from wall outlet, keep pressed the Power Button for few seconds to discharge of remaining harmful thing in your PSU.

after putting the memories in the black slots and then in the white slots I did the test and passed it right? as you can see in the image

i was very specific to state that the ram for CPU-0 was the source of the problem based on the error message and that reseating the cpu-0 ram modules or swapping them would either resolve the issue or point to which module was failing
