Question LED sync error with Adata XPG D50 3600mhz RAM ?

[anpham]

Dear all!
I have a trouble with 4 x 8G Adata XPG D50 3600mhz, installed on Asrock B660m PRO RS which supports ASRock Polychrome RGB Sync

3 of the 4 RAM sticks are Micron DRAM (according to CPU-Z)
1 of the 4 RAM sticks is Hynix DRAM

My trouble is: The 3 Micron RAMs are working properly with RGB Sync, but the Hynix one is not.
Hynix Dram only shows static color but not all, it exactly only show 3 colors: red, blue, purple in static mode. Other color, other mode => led is off

Any one have solution? I'm very confused now.

If you buy RAM sticks in a set, they all come from same OEM. My question is, why you have one stick Hynix?
