My corsair vengeance rgb rs 32gb kit not stable when XMP enable

[VAC]

I just bought two kits of Corsair Vengeance RGB RS 32GB (CMG32GX4M2E3200C16). The first time I installed 4 sticks in my PC, it posted very well and could reach 3600mhz with XMP enabled.

But the problem occurred when I shut down my PC for a night or a day. When I press the power button, the RAM LED turns on, the fans are running, but nothing happens on the screen. I tried to reset it many times, but had no luck. Then, I had to remove 3 of the sticks, reset the CMOS, and turn it on again. Still, there was a black screen, so I continued to reset until my PC finally booted to Windows with only one stick.

After that, I shut down the PC, went into the BIOS, and enabled XMP again. I restarted, and it posted to Windows normally.

I don't know what's wrong with my PC.

My specs are:

B660M Mortar DDR4 with the latest BIOS
Intel Core i5-12600K
64GB (4x16) RAM
Antec 750W Neo Eco

Thank you for your help.

I just recently ran into memory problems.  I have learned a lot!   Watch the video below.  However basically what I have found is the motherboard layout is critical to memory performance.  XMP however loads int the ideal memory parameters, but the motherboard layout might not support these speeds.  Hence you will not be stable with XMP because of the memory layout.   Additionally it is important with 2 dimms and 4 slots to put memory in the correct slots.  The motherboard's manual should tell you best slots to use.

This is why all manufacturers tell you not to combine kits. DDR5 is still too immature to get away with this when using 4 modules for most users. Swapping yet another RAM kit in is going to give your BIOS fits. Use the clear CMOS button if you’re truly stuck or most boards will bring you back to a safety screen if you hard shutdown from a failed boot.
