Question PC does not boot with new memory

[punisher_09]

Hello, I have the following system:
CPU R5 7600
MB Gigabyte B650 Gaming x v1.3 (latest bios version)
RAM 2x8GB 5200MHz DDR5
GPU RTX3060 12GB
SSD 2x M.2 SSD's + 1x S-ata SSD
HDD 1x S-ata 7200rpm
PSU Super Flower Leadex 2 gold 650w
Cooler Silentium PC Fortis 5

I bought yesterday a new memory kit, from XPG. The memory kit is 2x16GB and it has the code AX5U6000C4016G-DCLABK.
I will mention that using the old memory kit (2x8GB 5200MHz) the computer seems to work Ok.
After installing the new memory (the XPG) in 2 and 4 slots on the motherboard I entered into the bios and set it to "load optimized defaults", then I saved the bios and boot into Windows 11.
After a few minutes I restarted the PC and it got stuck, with the RAM led on the motherboard on. I wait about a few minutes and nothing happened. Only the ram led was on and the fans were on and there was no image on the monitor. Then I turn off the PC using the power button, and start it again. This time it normally boot. But when I restart it again, the same happens as before.
If I set the memory to EXPO 6000 40-40-40 1.35V (expo profile 1) then when restarting the PC it makes a single long beep and then then it boots only if I turn it off and reset the bios from clear cmos.

What should I do in order to make the XPG memory work normally with expo ?

Is the system stable with the new memory at default speeds? Also, if your motherboard BIOS fully up to date?

My bios is up to date.
I have not tested the stability. But I think that it is not stable if does not boot after restart.

I would return the ram if you can. Check the QVL sheet for your motherboard and try buying a kit that is on this list, as they should be tested compatible kits.

Sometimes ram compatibility can just be fickle, especially since it is the first generation of a new ram type.

The memory is on the QVL list.
I will return it.

What memory do you recommend to buy ?
