16GB DDR5 4800 UDIMM for Gigabyte B650 AORUS Elite

This 16GB DDR5 module runs at 4800MHz with CL40 latency and 1.1V operation. It is built as a single 1Rx8 rank on a 288-pin unbuffered UDIMM form factor. The kit targets owners of the Gigabyte B650 AORUS Elite AX motherboard who need a direct, compatible memory upgrade.

Single module kit simplifies installation

The package contains one 16GB stick, so there is no need to match multiple modules or populate specific slots in pairs. This reduces the chance of configuration errors during a first-time upgrade. The module uses major OEM chips from Samsung, Micron or Hynix and is stress-tested for stability.

No heat spreader keeps profile low

Without a heatsink the module fits tight spaces near large CPU coolers or compact chassis layouts. Standard 288-pin DDR5 keying ensures correct orientation in the motherboard slot. Builders who need ECC, registered buffering or higher capacities will need a different module type.

Questions about this item

Does the CL40 CAS latency affect how often I need to reseat or replace the module?

CL40 is a timing specification, not a wear factor. The module has no moving parts and no heat spreader, so it requires no periodic reseating or scheduled replacement under normal desktop use.

What limit appears first when the DDR5 4800 stick runs at full load for hours?

The 1.10 V operating voltage and lack of a heat spreader mean the memory chips reach their thermal ceiling before any electrical limit, so sustained throughput is bound by chip temperature rather than power delivery.

How much noise and heat does the 1.1 V UDIMM produce during all-day operation?

The stick is completely passive — no fan, no pump — so it adds zero acoustic noise. Heat output is modest at 1.1 V, but without a spreader the chips rely on case airflow to stay cool.
