OWC 8GB (4x2GB) DDR3 1333 CL9 desktop RAM

Ready-to-install desktop upgrade kit

This OWC kit supplies 8 GB of DDR3 memory across four 2 GB unbuffered DIMMs. It targets owners of desktop or workstation systems that accept 240-pin modules running at 1333 MHz with CL9 timing. The 1.5 V operating voltage matches the JEDEC standard for this generation. No heat spreaders or LEDs are fitted.

Plain black PCB with standard 240-pin layout

Each module uses a conventional green PCB in black colouring and the industry-standard 240-pin edge connector. The dual-channel kit designation means the four sticks are matched for paired-channel operation on compatible motherboards. Installation follows the usual DIMM slot procedure without special tools or clearance concerns. Non-ECC, unbuffered design keeps compatibility broad for consumer platforms.

Low-voltage operation keeps thermals modest

At 1.5 V the modules draw little power and generate minimal heat during typical desktop workloads. Absence of a heat spreader means they rely on case airflow, which is sufficient at this speed and density. Silent operation is assured because no active cooling is present. The kit delivers a straightforward capacity boost without adding thermal or acoustic load.
