Random question about RAM.
Random question about RAM.
I've always arranged my RAM kits one stick per kit per channel. This approach has consistently worked well for me, even though I haven't tested mixing speeds in reverse. Back in the SDRAM era, I mixed a 256MB 133MHz stick into slot A and a 128MB 133MHz stick into slot B on an old Pentium 4 system without any issues. Over time, this method has proven reliable across all systems I've upgraded. I've also accepted using speeds below the official limits—like running DDR-400 on an older machine or accepting DDR-333 on a DDR-333 system. Now that my setup uses DDR4-3200, which matches the supported standard for the 5900X, mixing still doesn’t cause significant stress on the memory controller. Running DDR4-4000 with more than two sticks would be even riskier.
