16 GB DDR3 Kit for Desktop Upgrades

This OWC kit supplies sixteen gigabytes of DDR3 memory across four unbuffered DIMMs. Each module is a 4 GB stick rated at 1600 MT/s with a CAS latency of CL11. The kit targets owners of desktop or workstation systems that use 240-pin DDR3 slots.

JEDEC Standard Limits at 1.5 Volts

The modules operate at the JEDEC standard voltage of 1.5 V and conform to the PC3-12800 speed grade. Because they are non-ECC and unbuffered, they rely on the platform memory controller for error handling and signal integrity. Maximum throughput is defined by the DDR3 1600 specification.

Four-Module Population Fills Four Slots

The kit contains exactly four 4 GB DIMMs, so it occupies four memory sockets on the motherboard. Buyers must confirm their board has four available 240-pin slots and supports a total of 16 GB in this configuration.

Questions about this item

Should I choose the 16GB kit or buy single 4GB modules instead?

The 16GB kit contains four matched 4GB sticks tested together for dual-channel operation, saving you the effort of verifying individual modules.

What does the PC3-12800 1600MHz rating actually deliver in my desktop?

It provides a peak transfer rate of 12800 MB/s at 1600 MHz with CL11 timing, giving noticeably snappier multitasking and faster large-file handling.

How does the 240-pin DDR3 interface limit this upgrade?

The 240-pin DDR3 DIMM fits only DDR3 motherboard slots and runs at the standard 1.5 V JEDEC voltage.
