Evaluating the NZXT Z790 and i9-13900k setup is interesting. With four RGB DDR5 RAM sticks, I expect better aesthetics and potentially improved performance compared to two sticks. There’s some debate about whether four DDR5 sticks perform equally well to two DDR5 or if the motherboard supports them. Since the Z790 hasn’t been officially released yet, QVL specs are still emerging, which might offer clarity soon. Comparing speeds: four DDR5 at 5600 MHz versus two DDR5 or four DDR4 at lower speeds—will the performance gain be noticeable? Let me know if you need more details!
DDR5 behaves identically to DDR4 regarding the number of sticks on the motherboard. The difference lies solely in the motherboard design, not in the RAM modules themselves. Depending on your needs, you might notice slight performance gains, minimal changes, or a significant effect since it’s not primarily about gaming but consistent daily use.
It can significantly affect performance depending on compatibility and stability. For example, a 12th Gen CPU generally doesn’t support 4 sticks of RAM at or above 5400 MHz, though some rare models did work with stable 4x16 configurations beyond that. The 13th Gen appears to have resolved many of these problems, and recent tests by Hardware Unboxed suggest 4x16 at 6000 MHz should function properly.
Two important cautions: NZXT has a poor reputation for board quality, so consider the brand’s history and product standards before purchasing. Also, think carefully about whether you truly need 4x16 modules—visual appeal doesn’t always justify the cost, especially if you’re displaying the machine or concerned about airflow issues. I recommend buying only what you genuinely require, rather than focusing on aesthetics.
