Combining different sticks can sometimes help, but it depends on how it performs. If it works, they’ll operate smoothly in flex mode. When a slower kit is present, everyone will run at its pace, which is the slowest one. It’s not a certainty, but you’ll need at least 48 gigabytes of RAM for it to function properly—anything less could cause issues.
It's incorrect. You may use various brands, sizes, and velocities, but please note that your memory performance will be restricted by the slowest RAM speed.
I tried 2x4 and 2x8, they worked okay. In dual channel mode, having equal GB seems to avoid flexibility issues. Likely it's dual channel with dual rank—if the sticks are 16GB in 16Gb modules or 8GB in 8Gb chips, make sure matching sticks are spaced one slot apart. You might need to lower memory frequency for higher rank settings.
They can indeed be combined. The bios will identify the size, speed, and delay of the smaller module and align both units accordingly. This statement is incorrect.
Avoid attempting it intentionally. When two modules match, use the suggested approach instead.
