processor supporting dual functionality 4x configuration
Consider an AM4 processor compatible with your NVMe setup and M.2 SSDs, ensuring it fits within your existing 16 PCIe x16 slots for a graphics card. Check if the board supports additional M.2 slots to accommodate future needs.
I'm checking the M.2 storage options you're using. The performance depends on the specific drives you have installed. Let me know what models you're running so I can suggest better fits.
AM4 motherboards typically lack two full x16 slots due to the CPU's 24 PCIe lanes being divided: 4 for the chipset, 4 for the first M.2 connector, and 16 for the PCIe x16 slot. Some boards can merge those 16 lanes into two x8 slots (physically x16). The chipset generates a limited number of PCIe lanes—usually 8 to 12—so you might only get an x8 slot plus a few x4 slots. To use such cards, the board must support splitting, which isn't common. For more PCIe lanes, consider threadripper or EPYC platforms. Threadrippers offer 64 lanes but are costly; EPYCs provide 128 lanes with many slots, though you'll need special DDR4 RAM. I shared recommendations for EPYC boards starting around $235 plus shipping in a previous post.
They move quite slowly. I’d prefer smaller, more efficient drives instead. There’s no need for four of them.
