Motherboard DRAM Light

[GoodbyeEveryone]

I am building my first PC and I have been having trouble with the motherboard and my RAM. I am using an ASUS TUF Gaming B650 Plus Wifi with a Ryzen 7 7700x CPU and a Corsair Vengeance RGB DDR5 6000MHz 2x24GB sticks. When I put both sticks in the recommended slots (A2 and B2) I get the DRAM light, if I put one stick into B2 it boots into the BIOS page (both sticks work).

Troubleshooting I have done:
[ol]
[li]Reset CMOS by removing the battery and then placing it back[/li][li]Updating the BIOS with the EZ Flashback using a USB drive[/li][li]Initially, the RAM I had bought was not compatible so I bought new RAM that I triple-checked was compatible from the ASUS motherboard support page[/li][/ol]
How can I test that the motherboard is faulty? And since I have 24 GB of RAM with one stick (which is sufficient for most), is there anything I can download or update once the system boots to fix the problem?

Are you sure they are 24GB sticks?

PS: well will you look at that, seems DDR5 also comes in 24GB variants - learnt something new today!

I ended up buying a new motherboard, pretty sure the original was faulty since I had no issues once installing the new one.

In BIOS, have you turned XMP mode on?
That 6000MHz is only achievable when overclocked.
Your ASUS TUF mobo only supprts up to 5200MHz without over-clocking.

OK, excellent - will close this as solved then. (y)
