Single 8 GB DDR3L module

This OWC memory module provides 8 GB of DDR3L 1333 (PC3L-10600) capacity in a single 240-pin unbuffered UDIMM. It operates at 1.35 V with CL9 latency and includes ECC error correction. The module is intended for select desktops, workstations and servers that accept DDR3L ECC unbuffered memory.

JEDEC and RoHS compliant

The module meets JEDEC-standard specifications and is RoHS compliant, making it a warranty-safe upgrade for OEM systems. No additional accessories or software are bundled; the change is the addition of ECC-protected DDR3L capacity to a compatible platform.

Verify DDR3L ECC unbuffered support

Before ordering, confirm that your motherboard or system accepts 240-pin DDR3L ECC unbuffered UDIMMs at 1.35 V. Check the maximum supported speed and total memory limit for your specific model. Ensure the platform does not require registered or fully buffered DIMMs.

Questions about this item

My motherboard has 240-pin DDR3 slots — will this module fit?

Yes, this is a 240-pin DDR3L UDIMM designed for desktop, workstation and server boards that accept unbuffered ECC memory.

Can I use this stick alongside my existing 1.35V DDR3L modules?

It runs at 1.35V with CL9 timing at 1333 MHz, so it will match other DDR3L 1333 CL9 modules at the same voltage.

Does this module require a heat spreader for normal operation?

No heat spreader is included; the module is rated for standard JEDEC operating temperatures without one.
