Additional Notes
- The Dell Latitude 5521 supports DDR4 memory at 3200 MHz, which represents a bandwidth ceiling of 51.2 GB/s per channel. Dual-channel operation across 2 SO-DIMM slots delivers theoretical throughput of 102.4 GB/s when both slots are populated with matching modules.
- SO-DIMM form factor restricts upgrade options to laptop-specific memory modules. Desktop DDR4 UDIMM sticks are physically incompatible with this architecture and will not install regardless of matching frequency or capacity specifications.
- Asymmetric population of the 2 slots (for example, one 32 GB and one 16 GB module) will force the system to operate in single-channel mode at the speed of the slower module, reducing available bandwidth by approximately 50 percent compared to matched-pair installation.
- The 64 GB maximum capacity ceiling means any single SO-DIMM exceeding 32 GB will remain incompatible, even if such modules become available in future DDR4 generations. The firmware and chipset do not support capacity combinations beyond this limit.
- DDR4-3200 modules sourced from third-party manufacturers may operate at reduced frequencies (DDR4-2933, DDR4-2666) if the system firmware does not recognize the higher-frequency JEDEC profile. Vendor-specific XMP profiles are unlikely to be applied by the BIOS without manual intervention.
- Installation of a single 64 GB module in one slot will leave the second slot unpopulated, eliminating dual-channel performance gains. This configuration trades throughput for maximum capacity.
