Interesting detail, some early boards featured three RAM slots instead of the two or four we commonly use today. However, those were not tri-channel configurations.
Many users benefit from increased memory capacity paired with faster bandwidth through dual, triple, quad, etc. channel setups. Mixing and matching DIMMs is common, particularly if budget constraints prevent purchasing a full 16GB dual-channel package right from the start.
The quantity of slots doesn't indicate that the board accommodates the same channel count. Just because a setup with three sticks on a four-slot board isn't ideal doesn't rule out its usefulness.
You can also observe this setting on the Mac Pro 4,1/5.1, as it offers top performance by leveraging Intel's X58 platform. It supports up to four memory sticks per CPU, especially useful with dual CPU trays for additional RAM. Some users notice improved speed by using only tri-channel and leaving one slot unused.
Only three out of four DIMMs indicate Tri-Channel support. Tri-Channel requires a CPU or chipset that supports it (like X58, X79, X99, X299, Threadripper, etc.), a motherboard that can handle Tri-Channel (most boards for these CPUs do), and at least three DIMM slots spread across the channels. While using all three or four slots isn't ideal, it's sometimes practical if the user has the right components and needs extra capacity.
Recently tested with 220ge and B450M-A (bottom-of-the-barrel hardware). Max OC single stick Corsair 3000 (sk hynix) at 2667mhz. Only very loose timings would push it higher, voltage doesn’t help much. Consider switching to a dual kit 4267mhz Trident Z B-die max clocks—currently at 1667mhz (3333mhz). The gap is noticeable compared to Corsair’s budget memory ICs versus some high-end dies.
