HP Z420 - 929 Fatal error - Mlc error detected cpu 0

After some mild gaming on my HP Z420, it started rebooting on it self and at the boot screen i can now see

929 FATAL MCA ARROR
MLC ERROR detected CPU 0

Any idea if the board is starting to act up or is the CPU, or something else?

( bios 3.65, Runing windows 7, 32Gb of ram, 2TB HD and 670 GPU)

Hello PN83,

 

Did you ever get this resolved?  I am experiencing the same thing on our Z420.

 

Thanks!

Hi,

 

has anyone found a solution for this?

 

I have the same error on a Z620 during Win10 installation. It stops installation process every time.

 

Cheers
