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.

Questions about this item

What maximum data rate does the DDR3 1333 PC3-10600 interface cap at in practice?

The kit runs at 1333 MT/s with a PC3-10600 peak bandwidth rating, so the practical ceiling is 10600 MB/s per module under standard JEDEC timings.

What physical slot and clearance does the 240-pin UDIMM need to fit?

Each 240-pin DIMM requires a standard desktop DDR3 slot; the modules have no heat spreader, so they fit under most stock CPU coolers without height conflicts.

How is the 4x2 GB kit installed, and which step do people often get wrong?

Power off, open the case, align the notch on each 240-pin module with the slot key, press firmly until both retention clips click, then populate matched-colour slots for dual-channel operation.
