OWC 4GB DDR3L 1600 CL11 SODIMM

This OWC 4GB module is a 204-pin DDR3L SODIMM rated at 1.35V with a speed of 1600 (PC3L-12800) and CL11 latency. It is an unbuffered, non-ECC 1Rx8 stick designed as a direct upgrade for specific NCR RealPOS XR5 (7603) and RealPOS XR7 POS (7702) systems.

Who This Suits

This upgrade suits technicians maintaining those exact NCR point-of-sale terminals who need a JEDEC-compliant, ROHS-compliant 4GB module. It is not for builders needing ECC error correction, registered buffering, higher capacities, different pin counts, other DDR generations, or compatibility with any system outside the two listed models.

Deciding Specification

The 204-pin DDR3L 1.35V form factor combined with explicit validation for NCR RealPOS XR5 (7603) and RealPOS XR7 POS (7702) is the single specification that determines fit; if your hardware is not one of those two models, this module is not the correct part.

Highlights

  • Boosts POS terminal speed with 4GB DDR3L 1600 CL11 module
  • Low 1.35V DDR3L voltage cuts power draw in NCR RealPOS XR5 7603
  • JEDEC-standard build ensures warranty-safe upgrade for RealPOS XR7 7702
  • Single 1Rx8 rank 204-pin SODIMM fits factory slot without modification
  • Tested to meet OEM specs for reliable multitasking in retail environments

Questions about this item

How do I install the 204-pin SODIMM into the RealPOS XR5 (7603) slot and what step is often missed?

Power off the terminal, unplug it, open the memory cover, align the notch on the 204-pin DDR3L module with the slot key, press firmly until the side clips click, then replace the cover before restoring power.

Will the 1.35V DDR3L 1600 module need any firmware update or periodic replacement during its service life?

No firmware updates are required for this JEDEC-standard 1Rx8 SODIMM; it is a solid-state component with no moving parts and no scheduled replacement interval.

What thermal or voltage limit appears first when the RealPOS XR7 (7702) runs this memory under continuous load?

The module operates at the JEDEC-specified 1.35V; sustained load does not introduce a lower voltage floor or a separate thermal throttle point beyond the system's own chassis cooling.
