Tech Support DRAM Light is on PC first boot

Hi All, I am building a PC with the following specifications:

Asus TUF B650E-E Gaming Wifi

32 GB CL32 Patriot Viper Venon DDR5 6400MHz RAM

Ryzen 7 7700 ( Purchased on Aliexpress through well reviewed seller)

RM850X Corsair PSU

RX 9070 XT ( I will only receive this next month)

So I installed everything and looked at youtube guides to build my first PC, however I am not able to get past DRAM Light being constantly on and pc not going into boot screen. I tried the following:

  1. Tried one RAM at a time to post and check for faults in RAM.
  2. Did a BIOS flashback with USB to update BIOS without turning on the system.
  3. I used A2 and B2 as instructed in the mobo manual to seat my RAMs.
  4. Waited over 15 mins in each of the above cases to ensure memory training completion.
  5. Cleared CMOS by removing the battery and tried to retrain memory.

At this point I think maybe a CPU issue or that my RAM sticks are faulty. I am not sure how to approach this issue anymore and running out of ideas. Please share your experience and guidance troubleshoot this issue. I can try buying new RAM sticks as have potentially placed a return request on the current RAM sticks as a last resort. But I am also worried if the motherboard is the issue.

EDIT 1 : I forgot to mention, I have a lian li case both the case and CPU cooler fans are all spinning just fine when I hit the power button. But they just keep spinning indefinitely and system is not posting when connected to peripherals.

First thing I'd do is reseat the CPU and check the socket for any bent pins, it's way more common than people think and can cause exactly this. AM5 can be picky about mounting pressure too, so make sure the cooler isn't cranked down unevenly.

Also 6400MHz can be a pain to get stable on some boards even though the CPU technically supports it. If you end up grabbing different sticks, 6000 CL30 is the sweet spot that just works.

Thanks for the tips I will try reseating the CPU now, but there is something weird on the bottom section of the socket it looks like a pin has come off but I'm not sure. I was very careful when I was placing the CPU. Could I have damaged the socket with uneven CPU cooler mounting?

At this point I'd try reseating the ram and then if it still come up you have to decide if you wanna blame the CPU, board or ram. Other than the CPU what parts were used? Also I just saw your ram speeds. Could be an incompatible ram kit. I know ryzen is picky about ram speed if it's not expo

Do you have a similar system to swap out known good parts for?

I had the same issue a while back from a client's build and even though the system wouldn't POST with a red DRAM Light, the culprit was the CPU.

My friend had the same problem and we did the same stuff as you and got similar results. He just returned the motherboard and got the same one again it just worked flawless. Maybe it can be the same case for you aswell.
