Capacity and configuration

This kit delivers 128GB of DDR5 memory across eight 16GB registered DIMMs. It targets workstations and high-end desktops that require large-capacity, error-correcting memory for demanding professional workloads.

Registered DDR5 constraints

Registered DIMMs add a buffer that improves signal integrity at high densities, but they require motherboards with RDIMM support and compatible chipsets. The modules operate at 1.25V with a CL36 latency profile at 5600 MT/s.

Upgrade path from unbuffered ECC

Moving from non-registered ECC or lower-capacity registered kits to this octo-channel configuration enables substantially larger memory footprints for virtualization, simulation and content creation. The jump is worthwhile when the platform supports registered memory and the workload exceeds the capacity or bandwidth of smaller kits.

商品問答

Should I pick the 128GB octo-channel kit or a smaller capacity for my workstation?

The 128GB kit provides eight 16GB modules for full octo-channel bandwidth on supported platforms. Choose it when your workload needs maximum capacity and channel utilisation; smaller kits reduce both.

What does the 5600 MT/s rating deliver in a real system?

At DDR5-5600 the modules transfer data at 5600 million transfers per second, giving up to 44800 MB/s theoretical bandwidth per module when the memory controller runs at that speed.

How does the 288-pin RDIMM interface limit performance?

The 288-pin DDR5 RDIMM interface supports ECC and registered signalling at 1.25 V, capping operation to the JEDEC DDR5 electrical and mechanical specification for registered DIMMs.
