Thank you for replying, but I'm running as XMP profile, as it sets the timing manually, so my kits are 10-12-12-31, it didn't change after I change it to "Furthest", do I have to change it to "Auto" and see?
The Auto value for VCCSA @ 2400MHz is about 1.23V, and I tried to increase it, from 1.25v to 1.4v, it doesn't help at all. I've also tried 11-13-13-31, it's still unstable. Does that mean I can only run it for 2133MHz?

I wonder why after I set the timings all to "AUTO" the system wouldn't even boot, stops at code 01.
