32GB DDR4 3200 SODIMM for laptops and NAS

This OWC module adds 32GB of DDR4 3200 memory to laptops, all-in-one PCs and compatible NAS systems. It runs at PC4-25600 with CL22 latency and 1.2V operation. The non-ECC, unbuffered design matches the QNAP RAM-32GDR4K0-SO-3200 specification for a direct replacement.

260-pin SO-DIMM without heat spreader

The stick uses the standard 260-pin SO-DIMM form factor and has no heat spreader, keeping the profile low for tight chassis. JEDEC and RoHS compliance means the module meets industry electrical and environmental standards. Installation is a straightforward DIY task in most supported devices.

Upgrade from lower-capacity DDR4 SODIMMs

Replacing a smaller DDR4 SO-DIMM with this 32GB module increases multitasking headroom for larger files and more simultaneous applications. The jump is worthwhile when the system supports 32GB per slot and the current memory limits workflow. OWC tests every module in-house to ensure long-term reliability.

Questions about this item

Does the DDR4 3200 PC4-25600 interface cap the module at CL22 latency?

Yes, this 32GB SODIMM runs at DDR4 3200 (PC4-25600) with a fixed CAS latency of CL22 as specified by the JEDEC standard for this speed grade.

Will the 260-pin SO-DIMM form factor fit a QNAP NAS slot that takes the RAM-32GDR4K0-SO-3200?

The module uses the standard 260-pin DDR4 SO-DIMM layout and matches the QNAP part number RAM-32GDR4K0-SO-3200 for direct replacement.

Is any BIOS setting or voltage change needed when installing this 1.2V non-ECC stick?

No, the 1.2V JEDEC-standard voltage is automatic; insert the unbuffered non-ECC SODIMM until the retention clips click, and the system will configure it without manual steps.
