8 GB DDR5 4800 Module

This 8 GB DDR5 4800 UDIMM targets users upgrading a desktop to a modern Intel platform. The unbuffered design fits standard 288-pin slots without ECC or a heat spreader. It suits everyday workloads and entry-level builds that need a single stick of memory.

Sustained Load Behaviour

Onboard PMIC regulates voltage locally at 1.10 V, keeping power draw steady during long sessions. On-die ECC corrects single-bit errors internally, protecting data integrity when the system runs for extended periods. The CL40 40-40-40-77 timings remain stable without active cooling.

Compatibility Checklist

Verify the motherboard supports DDR5 UDIMMs at 4800 MT/s and operates at 1.10 V. Confirm an Intel Z690 or compatible platform is used, as the module is optimised for that environment. Ensure a free 288-pin slot is available for the single 8 GB stick.

Questions about this item

Will this 288-pin DDR5 module fit my motherboard?

It requires a desktop board with a DDR5 288-pin UDIMM slot and a memory controller rated for 4800 MT/s.

Does the kit include a heat spreader or any extra cooling?

No, the module ships without a heat spreader and relies on case airflow.

What BIOS setting is needed to run at the rated 4800 MT/s CL40?

Enable the XMP or EXPO profile in BIOS; the SPD is programmed for 4800 MT/s at 1.10 V with 40-40-40-77 timings.
