16GB DDR5 4800MHz Desktop Memory

This A-Tech module is a 16GB DDR5 DIMM rated at 4800MHz with CL40 latency and 1.1V operation. It is an unbuffered non-ECC stick using a 288-pin form factor for desktop platforms. The memory is built as a compatible replacement for ADATA AD5U480016G-DT, AD5U480016G-R and AD5U480016G-S modules.

Replacement For ADATA DDR5 Modules

This unit replaces the ADATA AD5U480016G-DT, AD5U480016G-R and AD5U480016G-S parts directly. The jump is worth it when your system requires DDR5 4800MHz memory and you need a tested 16GB module that matches the original specifications. It restores standard DDR5 performance without a heat spreader.

Suits DDR5 Desktop Upgrades

This module suits users upgrading or repairing a desktop that takes a single 16GB DDR5 4800MHz DIMM. It is not for systems that need ECC, registered memory, lower voltage than 1.1V or a different DDR generation. Buyers should confirm their platform supports DDR5 4800MHz unbuffered non-ECC DIMMs before ordering.

Questions about this item

Will the 288-pin DDR5 DIMM fit my motherboard's DDR5 slots?

Yes, the module uses the standard 288-pin DDR5 DIMM form factor for desktop memory slots.

What is the correct way to seat the module so the 1.1V DDR5 4800MHz kit posts on first boot?

Align the notch with the slot key, press down firmly until both side clips click, and verify the motherboard is on the latest BIOS for DDR5 4800 support.

Does the lack of a heat spreader on this 16GB CL40 module mean I need to add cooling later?

No, DDR5 4800 at 1.1V runs within JEDEC thermal limits without a spreader; standard case airflow is sufficient.
