Question Asus Tuf Gaming B660m Plus D4 Wifi No post

[vandalblue]

Hello, i have a huge problem, build a new pc recently, but i can't make it post, and i have a dram loop (cpu, dram leds loops ) and no post, i can use only one module, tested each module and the rams are okay, no errors (memtest) but if i put 2 it just does not post, the motherboard recognizes only the last memory slot (B2) all other slots does not recognize the ram...

SPECS:

-I7 12700F
- Arctic Freezer II 360 a-rgb
-Asus Tuf Gaming B660m Plus D4 Wifi
-Ram 2x16 (32 Gb) Team TForce Vulcan Z 3200 Mhz
-Gtx 1080 Ti

The system just doesn't post and i don't have the money to buy another cpu to test, i'm missing something or it is just a bad motherboard/cpu? How to test if it is cpu or motherboard? Tried everything already, even removing the processor and re applying thermal paste, also there are no bent pins, also applied a correct uniform pressure to the cpu, the Ram modules are in the QVL of the motherboard, updated the Bios to the latest version... I'm desperate because i work with my pc :c


Please, help!
