    Which integrated memory controler does support DDR4 ALERT_n signal?

      Hello,

      I found that integrated memory controller of Intel Xeon E5-2600 supports DDR4 ALERT_n signal for Parity error. Does it support ALERT_N for CRC error also?

      I also found that some Intel processors have limited support of ALERT_n signal . Their datasheets say following:

      "Alert_n: This signal is used at command training only. It is getting the Command and Address Parity error flag during training".

      Does it mean that a memory controller would get the signal only during BIOS initialization and would ignore it after, even a DIMM module asserts the signal?

      Thank you

      Alex
