Ram die
Ram dies are components used in PCBs that provide power delivery. Mixing rams from different dies with matching timing can work, but it depends on compatibility and proper design. Always verify specifications before combining them.
RAM dies represent the real memory chips inside the memory modules. Only a few DDR4 manufacturers exist (Samsung, SK Hynix, Micron, and another less common one), each using various methods to produce these chips, offering different sizes, speeds, and features. For instance, Hynix DJR runs at very high speeds—possibly even 6GHz—but its performance doesn’t improve much. Samsung B die, on the other hand, operates at a moderate rate but with extremely low timing precision. Combining them is not advised because their characteristics clash, though it’s less critical now. It’s unusual to find two distinct chips causing system boot failures. Generally, each type has unique timing and controller behavior, which can prevent them from reaching their advertised XMP levels together.
Using DDR4 has kept me trouble-free so far regarding mixing chips during upgrades. I think you might face problems if you try to overclock the RAM later.
Sometimes you may need to adjust certain parameters manually, since even with identical modules and latency, timing differences can still occur.
