OWC 4GB DDR3 1866 SODIMM

This 4GB DDR3 1866 CL13 module uses the 204-pin SO-DIMM form factor and runs at 1.5V. It is built for laptops, all-in-one PCs and compatible NAS appliances such as the QNAP reference RAM-4GDR3LA0-SO-1866. The non-ECC unbuffered design matches standard consumer platforms.

DDR3 1866 practical limits

DDR3 1866 (PC3-14900) tops out at the JEDEC-defined 1866 MT/s data rate and CL13 latency. Systems that only support lower DDR3 speeds will down-clock the module automatically. The 1.5V operating voltage is the standard for this generation; 1.35V low-voltage slots cannot use this stick.

Straightforward laptop installation

Installation requires opening the memory compartment, aligning the notch on the 204-pin edge connector and pressing firmly until the retention clips engage. Common issues include inserting the module at an angle, leaving a clip unlatched or mixing capacities and speeds across slots, which can prevent the system from posting.

商品問答

Should I pick the 4GB module or add a second stick for 8GB total?

The module is a single 4GB DDR3 1866 CL13 SODIMM; adding a second identical stick doubles capacity to 8GB and enables dual-channel bandwidth on platforms that support it.

What does the PC3-14900 1866MHz rating deliver in my laptop or NAS?

It provides a peak transfer rate of 14900 MB/s at 1866 MT/s with CL13 latency, boosting multitasking and large-file handling in compatible DDR3 systems.

Does the 204-pin DDR3 SO-DIMM interface limit the speed I actually see?

The 204-pin DDR3 SO-DIMM form factor runs at 1.5V and is keyed for DDR3 slots only; the memory controller negotiates the highest common JEDEC speed, so the module operates at its rated 1866MHz when the platform supports it.
