I currently have an Intel Core i7-9700K and 32GB of Corsair Vengeance LPX DDR4-3000 CL16 memory (CMK32GX4M2D3000C16). I want a meaningful CPU upgrade, preferably switching to AMD, but I need to keep using this RAM. My system is built in a Louqe Ghost S1, so I need a mini-ITX motherboard. What CPU and motherboard combinations should I consider, and would my existing memory work reliably with them?

The most straightforward AMD option is AM4 with a Ryzen 7 5800X3D, or one of the less expensive 5000-series X3D chips such as the 5700X3D. AM4 uses DDR4, so your 32GB kit should work, although you may need to enable its XMP/DOCP memory profile in the BIOS. For a mini-ITX build, look at B550 mini-ITX boards from MSI, ASUS, Gigabyte, or ASRock, and verify that the board has a BIOS version supporting the CPU before buying.
If the upgrade is not urgent, AM5 with DDR5 gives you a newer upgrade path, but it means replacing your current memory as well. If keeping the DDR4 kit is the priority, AM4 X3D is the simpler gaming-focused choice. Your DDR4-3000 kit is usable, though faster DDR4 would be a modest improvement; replacing it is not necessary to make the system work.
Your other DDR4-compatible route is a 12th-, 13th-, or 14th-generation Intel processor paired with a DDR4 motherboard. A Core i7-13700K can use that memory on a compatible DDR4 mini-ITX board, but it produces considerably more heat and power than the 9700K. In a compact Ghost S1, the 5800X3D or 5700X3D is generally easier to cool. Make sure the exact board supports the CPU and has adequate BIOS support.
I was considering a 13700K, but cooling and power draw may make the AMD option more practical for this case.
For gaming, the Ryzen 7 5800X3D is still a strong drop-in-style platform upgrade even though you need a new motherboard. The 5700X3D is often the better value if available. Compared with the i7-9700K, the extra threads and large 3D V-Cache can improve frame-time consistency and CPU-limited performance in games such as Rust, Star Citizen, Counter-Strike 2, and The Finals, especially when paired with an RTX 5070. Results depend on resolution and settings, so check your CPU and GPU utilization before choosing.
Those are the games where I notice the bottleneck most, so the 5800X3D is probably the direction I’ll take.
Will any AM4 CPU work with this exact Corsair kit, and do you have a mini-ITX board recommendation for the Ghost S1?
