System-specific DDR4 SO-DIMM for select ASUS

This 4 GB module uses 260-pin DDR4 running at 2400 MT/s with CL17 timings. It is built for the ASUS Q170T motherboard, ASUSPRO E520, Chromebox 3 and FX503 notebook. The stick is unbuffered, non-ECC and operates at 1.2 V.

Thermals noise and power in normal use

The module runs at the standard 1.2 V DDR4 voltage and has no heat spreader. Passive cooling inside the target laptops and small-form-factor desktops keeps temperatures in check. No active fan or extra power draw beyond the slot specification is required.

Build fit and system constraints

One slot is filled by this single 4 GB stick; the platform supports up to 32 GB across two sockets. A 64-bit operating system is needed to address more than 4 GB total. Mixing with other modules will force all memory to run at the slowest installed speed. Buyers who need higher capacity or matched-pair bandwidth should look elsewhere.

Questions about this item

How do I install this 260-pin DDR4 SO-DIMM in my Chromebox 3?

Power off the device, open the memory compartment, align the module notch with the slot key, insert at an angle, then press down until the retention clips lock on both sides.

What maintenance or replacement will this 4GB CM512642400SO module need over time?

No scheduled maintenance is required; the module carries a limited lifetime warranty against manufacturing defects from Computer Memory Solutions.

What limit appears first when this CL17 DDR4-2400 memory runs under sustained load?

The 4GB capacity is the primary bottleneck; all installed modules operate at the speed of the slowest module or the CPU's maximum supported rate.
