It comes down to the specific board's QVL list. Crucial said my Ballistix were compatible, I found that not to be true. The only RAM I've not had issues with was selected from the board's specific QVL list ont he board manufacturer's website. I won't trust other sources after my experiences. Here is the manufacturer's list for your board with 3rd-gen Ryzen. Be aware that some RAM may be fine with your 3900X, but not, say, a 5900X. https://dlcdnets.asus.com/pub/ASUS/mb/So...s_X570.pdf Truth be told, I only ferreted out my problem through swapping components. RAM and GPU from another machine, no change, so the board was RMA'd. I wasn't thinking about it yet because it passed memtest86, but it happened the RAM was the same SKU / part #, so I only proved same RAM, same issue. Storage, GPU and one DIMM were transferred to an ASRock board with a 3600X. It ran, but with different issues. Installing the second DIMM produced a no-video startup / POST failure from the first board. This clinched it, so I looked into it, discovered QVL and ordered recommended RAM. Many say RAM is RAM and QVL doesn't matter, but I know first-hand that's not entirely true. I think it's becoming more of a thing, particularly with Ryzen. So check this list for your specific RAM SKU. If it's not there, the board / CPU may not like them. If you do swap RAM, keep in mind that above 3200 Mhz, the price-performance gap gets a lot wider... I usually recommend 3200, maybe 3600 if you can get a deal. My 5900X screams with 3200. Though if all you play is Fortnite, I doubt you really need a 5900X, unless you have a lot of background processes. Zen3 could give it more oomph over Zen2, but quite frankly, if I could have found a 3800X or 3900X, I would have been more than happy with that. I built a whole new system because my 1700 / GTX1650 rig had unstable gameplay recording no matter what I did. Seeing as this is the system that with the same RAM I now know doesn't play well with Ryzen, I wonder if the RAM was causing that too. Which would mean I probably built a whole new system when all I really needed was a better RAM kit. Edited October 10, 2022 by An0maly_76 Revised, more info
