OWC 16GB DDR3 1866 desktop module

This OWC module delivers 16GB of DDR3 memory at 1866MHz with a CAS latency of 13. It is built for desktop and workstation systems that use 240-pin unbuffered DIMM slots. The single stick provides a straightforward capacity increase for compatible machines.

JEDEC compliant 1.5V unbuffered design

The memory operates at the standard 1.5V and follows JEDEC specifications for broad compatibility. Its 240-pin UDIMM form factor fits directly into standard desktop slots without registration or buffering. A black PCB and lack of heat spreader keep the profile low for tight clearances.

Replaces smaller or slower DDR3 DIMMs

Swapping out lower capacity or slower DDR3 modules with this 16GB PC3-14900 stick raises the memory ceiling for multitasking and large file handling. The upgrade is most worthwhile when the board supports 1866MHz operation and the existing configuration leaves free slots or uses mismatched speeds.

Questions about this item

Will this 16 GB DDR3 module fit a standard desktop DIMM slot?

Yes — it is a 240-pin unbuffered non-ECC UDIMM built to the JEDEC DDR3 standard for desktop and workstation boards.

My motherboard specifies CL11 at 1866 MHz; will this CL13 stick still work?

The module runs at DDR3 1866 (PC3-14900) with a CAS latency of 13; the board will simply use the slower timing if it cannot match CL11.

Do I need any extra cooling or a heat spreader for this memory?

No heat spreader is included and none is required; the module operates at the standard 1.5 V without additional cooling.
