8GB DDR4 2400MHz Module

This SK hynix HMA81GU6AFR8N-UH is a single 8GB DDR4 2400MHz DIMM with CL17 latency and 1.20V operation. It targets desktop owners who need a straightforward capacity increase for everyday workloads. The 288-pin unbuffered design fits standard consumer motherboards without ECC requirements.

Upgrade from 4GB or slower DDR4

Replacing a 4GB stick or a lower-speed DDR4 module with this 8GB PC4-19200 part doubles usable memory and raises the data rate to 2400MHz. The jump is worthwhile when multitasking stutters or when a single-rank slot is the only one free. Systems already running 8GB at 2400MHz CL17 will see no practical change.

Fits a standard DIMM slot with 1.20V headroom

The module plugs into any desktop DDR4 DIMM slot wired for 1.20V unbuffered memory. No extra power connectors or cooling are required. Using this stick leaves remaining slots open for future expansion up to the board’s supported maximum.

Questions about this item

Will the 288-pin DIMM fit a standard desktop DDR4 slot?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor for desktop motherboards.

What is the correct way to seat the module so the retention clips click?

Align the notch with the slot key, press down firmly on both ends until the side clips snap closed automatically.

Does this 1.20V unbuffered stick need any firmware updates or heat-spreader cleaning later?

No firmware is required; dust the contacts and slot with compressed air if the system becomes unstable after years of use.
