RAM not working, what about the QVL ?

Hi, first post here !

I just finished my first build and I'm pretty happy with the result. In terms of power supply, everything seems to work properly, same for the case switches and LED. But I can't pass the POST.

It fails at the DRAM test (yellow LED) . I tried to change the slot (since it was A1 B1, and I saw in the manual that it should be A2 B2) but the result is the same.

Then I saw that the RAM I bought is not on my motherboard QVL (quality vendor list).

So I asked to return the product and I just ordered new RAM which is on that list.

* Faulty RAM: Kingston Fury RGB DDR5 5600Mhz (and it was very cheap compare to the new G.skill I ordered). * Motherboard: Asus Rog Strix B660G gaming, * CPU: Intel Core i5-13600-KF. * Both are compatible with 5600Mhz memory.

I just want to make sure if I did right, is there any other possible explanation I can't see ? How can I make sure the rest of the build (CPU and GPU) is working ?

Anyone experienced the same error with that MB or RAM ?
