16GB DDR5 5600MT/s Module

This 16GB DDR5 module runs at 5600MT/s with CL46 latency and 1.10V operation. It uses a 288-pin DIMM form factor and a single-rank 1Rx8 layout. The non-ECC unbuffered design suits standard desktop builds.

DDR5 Platform Limits

DDR5 memory requires a motherboard and CPU that both support the DDR5 standard and 288-pin DIMM slots. The module operates at the JEDEC 5600MT/s speed with CL46 timing at 1.10V. Maximum capacity and speed depend on the platform memory controller.

Pre-Installation Checks

Verify your motherboard accepts 288-pin DDR5 DIMMs and supports 5600MT/s at 1.10V. Confirm the board can run non-ECC unbuffered modules in single-rank configuration. Check BIOS version for DDR5 compatibility and ensure free DIMM slots are available.

Questions about this item

Is the 16GB DDR5 5600MT/s module the right capacity for my build?

This single module provides 16GB of DDR5 memory at 5600MT/s. It fits a 288-pin DDR5 slot and runs at 1.10V with CL46 latency, making it a straightforward upgrade for desktops that support DDR5.

What does the 5600MT/s rating deliver in actual use?

The 5600MT/s speed (PC5-44800) sets the maximum data rate the module can sustain. Real-world throughput depends on the memory controller and BIOS, but the module is rated for this transfer rate at CL46 and 1.10V.

How does the 288-pin DDR5 interface limit performance?

The 288-pin DDR5 DIMM interface carries the 5600MT/s signal at 1.10V. The module is unbuffered, non-ECC, single-rank (1Rx8), so the interface caps at the JEDEC standard rate without registered or ECC overhead.
