Help！How to get ECC error log of Xeon Ice Lake ?

[Admin123]

    I used Ice Lake processor(Intel® Xeon® Gold 6330) and GIGABYTE board to test DDR4 RDIMM.

    I used IMCi_CHi_MCi_STATUS.vaild to check whethere there is an ecc error, and it is useful to locate right sock, ctrl and channel. Then I used retry_rd_err_log to decode DQ\ROW\COL, but retry_rd_err_log.vaild is always zero which means I can't decode more info. 

    I suceeded in decoding ECC errors for Skylake-SP (also Intel® Xeon® Scalable Processor) by same way.  But it is invaild for Ice Lake, is there somthing I missed?

    Btw, I set ERROR_CONTROL.bit1 for Skylake-SP to enable mode-1, but bit1 is readonly for Ice Lake. So I did nothing with ERROR_CONTROL register.

Hi IntelSupport,

Thanks for your reply. 

Is it possible that there are some registers i haven't enabled , and it caused errors can't be logged to registers "retry_rd" ? 

Or ICE LAKE needs new registers to decode ECC error info,  instand of registers "retry_rd" which are used by SKYLAKE-SP? 

Best Regards
