MSI B550 Tomahawk no SPI_CLK

[McWhitePink]

Hi guys,

I have two same boards, does power on, but stuck in CPU check light,
measured the BIOS signals, found SPI_CLK has no signal, such that all other input and output doesn't have signal.
I checked there is no broken wire from BIOS ROM chip to CPU.

What other thing can I check?

I have one of these with faulty Ram slots A1 and A2, with ram in these, sticks on CPU light, put ram in B1 or/and B2 and it boots fine, maybe that will work for you? Still trying to fix my slots
