question about RAM

Hello,

I'm an old AM4 user when I recently got upgrade to 5700x3d and I feel the need to upgrade/increase my ram. At the moment I have 2 sticks of G.SKILL F4-3200C14D-16GTZ Trident Z Series 16 GB. My mobo is an old ASRock Taichi x370. I was hoping to swap to KF432C16BB1K2/32. I started by contating both ASRock and Kingstone to be sure they would work. and the answer I got from both is that it should work but we can't be sure - it's up to you(me) from both of them. What are your suggestions? The whole idea of getting 5700x3d was to avoid swapping motherboard.
