4GB DDR4 2400MHz Desktop Module

This 4GB DDR4 2400MHz PC4-19200 DIMM is built for desktop computers that need a straightforward memory upgrade. It fits standard 288-pin slots and runs at the JEDEC-standard 1.2V, making it a direct replacement for the Hynix HMA451U6AFR8N-UH module. The single-rank 1Rx8 layout keeps installation simple for home users and system integrators alike. Builders who need more than 4GB per slot or who require ECC error correction should look elsewhere.

Speed and Voltage Confirmation

The decisive specification is the tested 2400MHz frequency at 1.20V, which determines whether the module matches the motherboard's supported memory profile. If the board only accepts lower speeds or different voltages, this stick will not operate as intended. No other timing or latency figures are supplied, so compatibility rests entirely on this speed and voltage match.

Tested Reliability and Support

Every module undergoes quality-assurance testing before it ships, which reduces the chance of early failures during installation. A lifetime warranty covers the part for as long as you own it, and US-based technical support is available before, during, and after the purchase to help with compatibility checks or troubleshooting. No additional software or accessories are bundled with the memory.

Questions about this item

Will this 4 GB DDR4 2400 MHz module fit my desktop motherboard?

The module uses the standard 288-pin DIMM form factor and runs at 1.20 V, which matches the DDR4 specification used by most desktop boards. Check your motherboard manual to confirm it supports DDR4 2400 non-ECC unbuffered memory.

Can I add this stick alongside the memory already installed?

Yes, provided your board has a free DDR4 DIMM slot and supports 4 GB modules. Mixing speeds is possible, but all modules will run at the speed of the slowest stick.

Is this the correct replacement for a Hynix HMA451U6AFR8N-UH module?

The product is listed as a compatible replacement for that exact Hynix part number, matching capacity, speed, voltage, and 1Rx8 organisation.
