8GB DDR4 2400MHz SODIMM

This 8GB DDR4 2400MHz CL17 SODIMM module provides a direct memory upgrade for compatible ASUS Vivobook X series notebooks. It is built for users who need to add capacity to a single SO-DIMM slot in models such as the X509, X540BA, X540UB, X550VQ and X571GT. The unbuffered, non-ECC design matches the original specification for these systems.

260-pin SO-DIMM form factor

The stick uses the standard 260-pin SO-DIMM layout and operates at 1.2V, fitting the existing slot without hardware changes. Because the platform has only one memory socket, this module occupies the sole slot and frees no additional sockets for further expansion. All memory in the system will run at the slowest installed module or processor capability.

8GB capacity with 16GB, 20GB or 24GB max

The 8GB capacity works with a 64-bit operating system to utilise more than 4GB of memory. The platform supports a maximum of 16GB, 20GB or 24GB depending on the specific notebook model, so this module leaves headroom only where the CPU and chipset allow higher densities. Buyers who want more storage or builders who need a second card will not be served by this single-stick kit.

Questions about this item

Will the CL17 latency become a bottleneck during sustained workloads?

The module runs at CL17 17-17-17 timings at 2400 MHz; under sustained load the CAS latency remains fixed at 17 cycles, so the limit you hit first is the 2400 MHz bus speed rather than a latency increase.

How much heat or power does this stick draw when the laptop runs all day?

Rated at 1.2 V and unbuffered without a heat spreader, the SODIMM draws minimal power and produces little extra heat during continuous operation inside the notebook chassis.

Which specific notebook models must I already own for this memory to work?

This 260-pin DDR4 SODIMM is validated for ASUS Vivobook X509, X540BA, X540UB, X550VQ and X571GT notebooks; one of those systems is required for guaranteed compatibility.
