I have crucial 4800 @ CL40 rams and when I enable XMP profile system isn't stable. However, after I changed to auto, it still runs at 4800mhz and all timing looks correct including tRC at 115 (however, CPU-Z does show XMP these rams tRC should be at 116, not 115). Could be a stupid question but have you update to the latest bios?

Yes I have updated the BIOS. This problem has persisted with BIOS versions 702 and 802 😞

I did not know there is a 0802 bios. I have the same mobo as you and I am currently on 0702 bios. I've attached my CPU-Z memory timing.

Yeah the 0802 version was posted on these forums by Shamino last week.
Just out of curiosity, are you using 4 sticks of RAM or just 2? I'm using 4 identicle sticks of Kingston Fury Beast.
I've seen some people reporting problems when all 4 DIMMS are populated but things are absolutely fine when only 2 DIMMs are populated (namely DIMMs A2 and B2). If A1, A2, B1, B2 are all populated, others said they also can't get past 4400Mhz without running into stability issues too.
Also, are you running all settings on Auto? Or have you tweeked any of them manually?

Sorry for whatever reason when I responded on phone with the same account, my user name changed to TQI1127...
So I installed 4 sticks of rams and they are running on 4000mHz CL 32. But interestingly, lower speed tighter timing makes my performance such better...
TimeSpy (4) sticks of rams @ 4000mHz CL32: https://www.3dmark.com/spy/24636792 CPU: 17551 GPU: 20491 Overall: 19988
TimeSpy (2) sticks of rams @ 4800mHz CL40: https://www.3dmark.com/spy/24335897 CPU: 15281 GPU: 19851 Overall: 19102
So running at lower clock with tighter timing is better. You should see all the timespy top scores are DDR4 mobo with 12th gen cpu.

You're probably getting better scores with 4000mhz because you have 4 sticks of RAM installed, not because the timings are tighter.
Try running another test with only 2 sticks of RAM but downclock them to 4000mhz
Then run another test with only 2 sticks of RAM but this time clock them at 4800mhz.
I'm willing to bet the 2 sticks running at 4800mhz give the highest score.
