OWC 8GB DDR4 SODIMM for NCR POS CX7 and CX8

This OWC module is an 8GB DDR4 2400 SODIMM built specifically for the NCR POS CX7 All-in-One POS (7772) and CX8 POS (7736). It provides a direct memory upgrade for those point-of-sale systems. The 260-pin form factor matches the slots in these units.

JEDEC-standard 1.2V operation with no heat spreader

The module runs at the standard DDR4 voltage of 1.2V and is unbuffered non-ECC with a CL17 latency. It carries no heat spreader, relying on the system's existing airflow. JEDEC and ROHS compliance ensures the upgrade is warranty-safe for the supported hardware.

Single 8GB 1Rx8 module at DDR4 2400 PC4-19200

This kit consists of one 8GB stick organised as 1Rx8, rated for DDR4 2400 (PC4-19200). It adds exactly eight gigabytes of capacity; systems requiring a matched pair or a larger total capacity will need additional modules.

Questions about this item

How do I install the 260-pin SODIMM in my NCR POS CX7 (7772) and what step is often missed?

Power off the terminal, unplug it, open the memory access panel, align the notch on the module with the slot key, press firmly until both side clips click shut, then verify the new 8GB appears in BIOS before closing the case.

What maintenance or replacement will this DDR4 module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and no moving parts, so replacement is only necessary if a memory test reports errors or the system fails to recognise the 8GB capacity.

What limit appears first when the POS CX8 (7736) runs sustained workloads with this CL17 memory?

The CAS latency of 17 cycles at 2400 MT/s sets the baseline access delay; under continuous load the memory controller will hit that timing wall before bandwidth or voltage headroom becomes a bottleneck.
