Single-module DDR3 upgrade

This OWC module adds four gigabytes of DDR3 1066 memory to the NCR POS N3000 Site Controller (1657). It uses the 204-pin SODIMM form factor and runs at 1.5 volts with CL7 latency. The stick is unbuffered, non-ECC and built to JEDEC PC3-8500 specifications.

Fits the N3000 site controller only

The part is validated for the N3000 (1657) and will not work in systems that require a different pin count, voltage or DDR generation. Buyers who need ECC error correction, registered modules, higher capacities or a different memory standard should look at other products.

Steady throughput under load

Because the module is unbuffered and non-ECC, sustained workloads behave like any standard DDR3 SODIMM at 1066 MT/s. No heat spreader is fitted, so adequate chassis airflow keeps temperatures stable during continuous operation.

Questions about this item

What type of memory slot must the NCR POS N3000 Site Controller (1657) have to accept this module?

The system must provide a 204-pin DDR3 SODIMM slot that runs at 1.5 V and supports PC3-8500 1066 MHz CL7 unbuffered non-ECC memory.

Can I keep an existing DDR3 1066 CL7 SODIMM in the second slot alongside this 4 GB module?

Yes, provided the other module is also a 204-pin 1.5 V unbuffered non-ECC DDR3 1066 CL7 SODIMM; the controller will run both at the shared 1066 MHz speed.

How do I verify the upgrade is recognised after installation?

Power on the N3000 Site Controller and open the BIOS or operating-system memory summary; it should show the additional 4 GB DDR3 1066 module present and running at the correct speed.
