For some with 4 sticks of DDR5 (64GB) there have been problems with the XMP profile, I have the Corsair Vengeance 4800MHZ and depending on which BIOS I have been running the ram between 4266 and 4600, the latest BIOS 1720 for me is the worse yet. Enough rambling, this is what works for me and hopefully if you are in the same boat this will help
1. Go into Bios 2. Go to Extreme Tweaker 3. Select XMP1 (if u have already got it enabled then select xmp 2 then Xmp1 again to clear settings) 4. Scroll all the way down to the bottom 5. Change the voltage for DRAM VDD and DRAM VDDQ to 1.25, I did try 1.2 at first which worked but over time during gaming it crashed 6. Open Advanced Memory Voltages tab which is right at the bottom 7. Change PMIC Voltages to 'By Per PMIC'
Save settings and let the memory retrain itself, if u still experience BSOD try increasing the VDD and VDDQ to 1.3

My post was to help those in the same shoes as me, I do not work for Asus, it is a solution that can help justify paying x amount for 4 sticks of RAM but only getting stock speeds and this is why I posted as it has been frustrating and nobody else seems to have mentioned this simple fix 🙂
