OWC 4GB DDR3L SODIMM for NCR POS

This 4GB DDR3L SODIMM module is built for NCR Columbus 900 and P1235 POS systems. It targets retailers and service technicians who need a direct replacement or a simple capacity increase for these specific point-of-sale terminals.

4GB capacity at DDR3L 1600 CL11

The single 4GB rank runs at 1600 MT/s with CL11 latency and 1.35V operation. It handles typical POS workloads and multi-window tasks comfortably; memory-intensive analytics or virtualisation will exceed the available headroom.

JEDEC 204-pin unbuffered non-ECC build

The module follows JEDEC and RoHS standards with no heat spreader. The 204-pin SODIMM edge connector fits the SO-DIMM slots in the Columbus 900 and P1235 chassis, allowing a straightforward tool-less upgrade.

Questions about this item

Will this DDR3L 1600 CL11 module run reliably with the existing memory in my NCR Columbus 900?

The module follows JEDEC-standard DDR3L 1600 CL11 timing at 1.35 V, so it will match the speed and voltage of the factory-installed SODIMMs in the Columbus 900 and P1235 systems.

How can I confirm the 4 GB stick is recognised correctly after I install it?

After seating the 204-pin SODIMM, the BIOS or OS memory report should show a single 4 GB DDR3L 1600 (PC3L-12800) module at CL11 running at 1.35 V.

What comes in the box and do I need any extra parts?

The package contains one OWC 4 GB DDR3L 1600 CL11 1.35 V 204-pin non-ECC SODIMM; no tools, cables or additional memory are required for installation.
