How to enable eADR?

[Aoyang-Tong]

Hello, 

Currently, I'm using an Intel(R) Xeon(R) Gold 6330 CPU @ 2.00GHz with Intel Optane Persistent Memory 200 Series in App Direct Mode. I have noticed that the Extended Asynchronous DRAM Refresh (eADR) is supported in the 3rd generation Intel Xeon Scalable Processors. But how can I enable eADR support, or how do I know if eADR is enabled or not?

Thanks.

Hi Aoyang,

Thank you for posting on Intel community.

Please note eADR is enabled by default on the 3rd Gen Xeon processors.

Since you confirmed the server board used is SITONHOLY IW2221-2GR.

We request to check with the server manufacturer if the BIOS has integrated this eADR feature.

We request to review the BIOS configuration for this feature after checking the same.
