Hi, yes it's doable. Your R9 5900X pairs well with those RAM modules. Just ensure the RAM matches the form factor and speed requirements. Your ASUS ROG B550-E supports dual-channel configurations, so F4-4000C18D-32GTZN or F4-4266C19D-32GTZR should work nicely.
This performance may vary and isn't necessarily better than 3866 MHz.
It's feasible to achieve those speeds, but you'll have to be fortunate to find a CPU/RAM pair that exceeds 3600 with RAM and delivers real gains. The relationship between RAM speed, timings, and infinity fabric frequency makes it quite challenging to boost performance significantly with top-speed RAM on Ryzen processors. Unless you're using 2400 MHz RAM now, it's usually wiser to invest elsewhere. A superior cooler would help your CPU operate at higher frequencies, such as for better efficiency.
It seems to vary a bit depending on the day, but overall 3200C14 feels similar to 4000C15 for gameplay. Some games might notice a difference, though. My 5900 handles 1866 smoothly without much adjustment, but 1900 1:1 needs tweaking, especially with four sticks. My 5600X manages 2K 1:1 with two sticks, but it still doesn’t match my current configuration. Right now I’m using 1866 1:1 14-14-14-34 1T 1.5v with PBO @ +150.
I believe the worst memory controller I've encountered was 1.19v for the DDR3600 4sticks, with a 2x16 likely to perform even worse. If you're asking these questions, GSKill B-Die is a solid choice—I saw them recently and it's not a guarantee of perfection, but it's decent. https://www.neweggbusiness.com/product/p...20-374-084 You could try the DDR4800 and adjust the FCLK ratio to achieve a 3:2 ratio, though I think it'll lag behind a 2x16 3733 in real-world use. On Intel benchmarks, the DRDR4 4000 CL15 shows about 2% improvement over the DRDR3 3733, but everything runs much hotter—stuck on 3666 on an X570 after adding four sticks.
2x8 G.Skill Trident Z Royal 3200C14 paired with 2x8 Trident Z Black and White 3200C14. For larger clocks I use my Royals. I can also run 4x8 1:1 flat 14s. Otherwise, I get whea’s. My Royals have been tested at 4400C15, though not stable, they’ve still worked.
The royals are truly amazing, I've given it the title: "THE RAM FOR THE WEALTHY"
