Hello
If this is happening when you are turning the server on for the first time then you likely have a loose DIMM. I would suggest reseating all of the memory.
Training is when the controller(PCI, memory) negotiates/trains with the device to a method both can perform. Training errors are usually caused by failed devices or devices that are not properly powered or fully seated in the slot.
Thanks
