OWC 4GB DDR3L 1866 CL13 ECC Unbuffered UDIMM 1.35V desktop RAM

OWC 4GB DDR3L 1866 ECC UDIMM

This module is a single 4GB DDR3L 1866 PC3L-14900 CL13 unbuffered ECC UDIMM built for select desktops, workstations and servers that require error-correcting memory. It operates at 1.35 volts and follows JEDEC-standard specifications for a warranty-safe upgrade.

240-pin DDR3L form factor and black PCB

The stick uses the standard 240-pin DDR3L DIMM layout with no heat spreader and no LEDs, so it fits into ordinary desktop or server memory slots without extra clearance concerns. Unbuffered ECC organisation means the memory controller handles error correction directly, which suits many workstation and NAS platforms.

Check your board for DDR3L 1.35V unbuffered ECC

Verify that the motherboard or system accepts DDR3L at 1.35 volts and can run unbuffered ECC UDIMMs at 1866 MT/s with CL13 timing. Some platforms only support registered ECC or require 1.5 volt DDR3, so consult the vendor memory-qualified list before ordering.
