OWC 8GB DDR5 4800 CL40 1Rx16 262-pin 1.1V SODIMM laptop RAM

8 GB DDR5 SODIMM for Laptops and NAS

This 8 GB DDR5 module is built for laptops, all-in-one PCs and NAS units that accept 262-pin SO-DIMMs. It delivers a straightforward capacity increase for everyday multitasking and larger file handling. The stick is unbuffered, non-ECC and runs at the standard 1.1 V. Buyers who need more than 8 GB per slot should look elsewhere.

JEDEC-standard thermals and power

The module follows JEDEC DDR5 4800 specifications with CL40 latency and 1.1 V operation, so it draws only the power the platform allocates for a standard SO-DIMM. No heat spreader is fitted, relying on the system's own airflow for cooling. Acoustic impact is negligible because the component has no moving parts. Builders who require lower latency or higher voltage headroom will not find it here.

4800 MT/s CL40 DDR5 speed rating

The single decisive figure is the 4800 MT/s (PC5-38400) CL40 rating, which must match the memory controller's supported speed grade. If the host platform only runs DDR5 at a lower data rate, the module will downclock automatically. Systems that demand a faster grade or a different CAS latency cannot use this module at its rated specification.
