Ryzen 3600 x470 ram issues

[jdm_freek]

so I gave my son my 8600k Z390 platform and switch to a Ryzen 3600 paired with a MSI x470 Gaming plus 

I know I should've went with a X570 but at $159 it made more sense to go with the MSI X470 Gaming plus for $79

So my issue is I was using a kit of G.SKILL Aegis 16GB (2 x 8GB)  Model F4-3000C16D-16GISB which says its compatible 

but when I populate slots 2 & 4 the rgb turn blue and no post, work fine with one stick ???

now I swapped ram to a 2x4 kit of Patriot DDR4 3000 viper and it works just fine.

Any advice ???

Does the bios have a failed memory boot feature? I just found it was added to this MSI X570 im reviewing. Saved me a lot of headaches from doinf Clear CMOS.

Kind of seems like the MB is trying to load the XMP profile and is failing. Otherwise why would the other kit work fine? Unless the XMP is disabled for the viper kit.

Just a guess. Memory is a picky thing. Though I would think 3000 speeds would boot up no problem on 3600 Ryzen.

Edit: I found the specs
