Which integrated memory controler does support DDR4 ALERT_n signal?

[AAlex39]

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

shalex, I apologize for the delay.

If the Xeon processor supports DDR4 then it supports Alert_n feature. However, if you would like to get more information on how this feature works the right place to ask questions would be https://software.intel.com/en-us/forum https://software.intel.com/en-us/forum.
