16GB DDR3 1333 Kit for Desktop Upgrades

This OWC kit delivers 16GB of DDR3 memory in four 4GB modules rated at 1333MHz with CL9 latency. It targets owners of desktop systems that use 240-pin unbuffered DIMMs and need a straightforward capacity increase. The 1.5V JEDEC-standard voltage ensures broad compatibility with older workstations and PCs.

Simple DIMM Installation with Common Pitfalls

Installation is a basic DIY task: power down, open the case, align the notch on each 240-pin module, and press firmly until the retention clips click. The most frequent issues are failing to seat all four sticks fully, mixing modules of different speeds, or neglecting to enable the correct memory profile in BIOS.

16GB Capacity for Multitasking Headroom

The 16GB total (4x4GB) comfortably handles everyday multitasking, larger document sets, and multiple browser tabs on supported DDR3 platforms. Performance tapers off when applications demand memory bandwidth beyond the PC3-10600 specification or when the platform's memory controller limits usable capacity below the installed amount.

Questions about this item

How can I confirm the kit is running at 1333 MHz CL9 after installation?

Open the BIOS or a system-information tool such as CPU-Z and verify the memory frequency reads 1333 MHz with timings of 9-9-9-24 at 1.5 V.

What does the 16 GB kit contain and is anything else required?

The package includes four 4 GB 240-pin UDIMM modules; no additional parts or cables are needed for a standard desktop DIMM slot.

Which capacity should I choose if my board supports up to 32 GB?

This 16 GB kit (4 × 4 GB) fills four slots; if your motherboard has only two slots or you want room to expand later, a 2 × 8 GB kit would be the better fit.
