OWC 4GB DDR4 2133 SODIMM

This OWC module is a 4 GB DDR4 2133 CL15 SODIMM built to replace the QNAP RAM-4GDR4K0-SO-2133 part. It runs at 1.2 V, uses a 260-pin layout and is unbuffered non-ECC memory rated to JEDEC PC4-17000 standard. The stick carries OWC part number 2S1D41R804GB and has no heat spreader.

Suits laptops NAS and mini systems not ECC platforms

The memory fits laptops, all-in-one PCs, mini desktops, micro servers and NAS appliances that accept standard DDR4 SO-DIMMs. It will not work in systems that require ECC registered modules or a different pin count. Buyers needing error-correcting memory or higher capacities should look elsewhere.

260-pin DDR4 SO-DIMM form factor decides fit

The single specification that determines compatibility is the 260-pin DDR4 SO-DIMM form factor combined with 2133 MT/s speed and CL15 timing. If the target device calls for this exact pin layout and voltage the module will install; otherwise it will not seat or function.

Questions about this item

Should I pick the 4GB module or look for a larger capacity?

This module provides 4GB of DDR4 memory. If your system has a free 260-pin slot and supports up to 4GB per slot, this part adds that amount directly.

What does the 2133MHz speed rating mean once the module is installed?

The module runs at 2133MHz (PC4-17000) with CL15 latency at 1.2V. Your laptop or NAS will operate the memory at this speed if the platform supports DDR4-2133; otherwise it will downclock to the highest supported speed.

Is the 260-pin SODIMM interface compatible with my QNAP NAS?

Yes. The 260-pin DDR4 SO-DIMM form factor matches the QNAP RAM-4GDR4K0-SO-2133 specification, so it fits the same slot and meets the same JEDEC standard.
