Why Server Memory Modules Have More Chips than Desktop Memory

Server memory modules contain many more chips than desktop DIMMs because they use ECC, which adds extra parity chips, and they employ registered or load‑reduced designs that include a register clock driver and, for LRDIMMs, a data buffer, all of which increase the chip count per rank.
