Target system upgrade
This 8 GB DDR4 SODIMM is built for laptops, all-in-one PCs and QNAP NAS units that accept 260-pin memory. It replaces the OEM modules RAM-8GDR4K0-SO-2400 and RAM-8GDR4K1-SO-2400 with identical specifications. The unbuffered, non-ECC design suits mainstream consumer and small-business platforms.
Speed and latency match
The module runs at DDR4 2400 (PC4-19200) with a CAS latency of 17 at 1.2 V. JEDEC compliance guarantees the rated timing without manual tuning. Backward compatibility allows it to operate in slots rated for 2133 MHz, though the stick itself is a single 2400 MHz part.
Simple slot installation
Insert the 260-pin stick into a free SO-DIMM socket until the side clips click; no tools or firmware updates are required. The low-profile board fits tight chassis without a heat spreader. Common issues arise only when the host BIOS limits total memory or enforces an unsupported rank configuration.

Questions about this item
What does the 2400MHz CL17 rating actually deliver inside a laptop or NAS?
The module runs at 2400MHz with CL17 latency, giving a PC4-19200 bandwidth rating that the system will use automatically at its supported speed.
How does the DDR4 PC4-19200 interface limit real-world throughput?
The DDR4 PC4-19200 standard caps the theoretical maximum transfer rate at 19200MB/s; actual throughput depends on the host controller and number of populated slots.
Does the 260-pin SO-DIMM form factor need any special bracket or clearance?
It uses the standard 260-pin SO-DIMM outline at 1.2V with no heat spreader, so it fits regular laptop, mini-desktop and NAS slots without extra hardware.
