System-specific DDR4 kit

This 8 GB kit contains two 4 GB DDR4 DIMMs rated at 2133 MHz with CAS latency 15. It is built for desktops or workstations that require unbuffered non-ECC memory in matched pairs. The modules use a 288-pin layout and operate at 1.2 V.

DDR4 2133 speed ceiling

The memory runs at DDR4-2133 (PC4-17000) and will down-clock to match the slowest module or the processor's memory controller. Mixing with faster sticks provides no gain, and a 64-bit operating system is required to address the full capacity.

2Rx8 rank configuration

Each DIMM uses a dual-rank 2Rx8 organisation, which determines how the memory controller accesses the chips. Verify that your platform supports this rank structure before purchase, as an incompatible rank layout can prevent the system from posting.

Questions about this item

Should I choose the 2×4 GB kit or a single 8 GB module?

The kit provides two 4 GB DIMMs for dual-channel operation, giving 8 GB total capacity and matched timings of CL15 at 2133 MHz.

What does the 2133 MHz speed mean once installed?

The modules run at 2133 MHz with CL15 latency at 1.2 V; actual speed will match the slowest module or the CPU memory controller limit.

How does the 288-pin DDR4 interface affect compatibility?

The 288-pin DDR4 DIMM fits standard desktop DDR4 slots and is unbuffered non-ECC, so it works with consumer platforms that support DDR4 memory.
