4GB DDR4 2400 SO-DIMM module

This 4GB DDR4 2400 CL17 SO-DIMM stick is built for ASUS ROG ZX53VW and TUF Gaming FX505DD, FX505DT, FX505DU notebooks. It targets owners of those specific laptops who need a single 4GB upgrade to reach 8GB, 16GB or the platform maximum of 32GB across two slots.

Check your laptop model and slot count

Verify the exact model name matches ROG ZX53VW, TUF FX505DD, FX505DT or FX505DU before ordering. The platform uses two 260-pin SO-DIMM sockets supporting up to 32GB total. A 64-bit operating system is required to address more than 4GB of installed memory.

Unbuffered 1.2V stick for dual-channel builds

The module is an unbuffered, non-ECC 2Rx8 design running at 1.2V with CL17 timings. It installs directly into an empty 260-pin slot and, when paired with an identical stick, enables dual-channel operation. Mixing with slower modules will cause all memory to run at the lowest common speed.

Questions about this item

Does the module arrive alone or with any installation hardware?

The package contains one 260-pin DDR4 SO-DIMM stick; no brackets, screws or tools are included.

Should I pick the 4 GB stick or look for a larger capacity for my TUF FX505DU?

The laptop supports up to 32 GB across two slots, so a single 4 GB module works but adding a second stick later will give more headroom.

What does the 2400 MHz rating actually deliver inside the ROG ZX53VW?

The memory runs at DDR4 2400 with CL17 timing at 1.2 V, and the system will operate at the slowest installed module speed.
