Hi Tony, Jason,

Gentle ping on this small EDAC/ie31200 change that adds two more Alder Lake-S device IDs for ECC-capable part.

Reviewed-by: Qiuxu Zhuo <qiuxu.zhuo@intel.com>

Could you please pick this up for the EDAC tree (ras edac-for-next)?

Thanks,
- Kyle

Hi All,

Confirmation EDAC works on 8P+4E (DID 0x4668) configuration as well, using ECC DDR4 UDIMM sticks. Validated on i7 12700 and Kingston 2666MHz ECC RAM.
