Kit capacity and purpose

This 256 GB kit contains eight 32 GB DDR4 3200 ECC UDIMM modules designed for servers and workstations that support unbuffered ECC memory. It adds 256 GB of dual-rank capacity to compatible platforms.

Platform compatibility check

The modules are 288-pin DDR4 DIMMs running at 1.2 V with CL22 latency and dual-rank x8 organisation. Verify that your system specifically accepts DDR4 ECC UDIMM memory before ordering, as desktop and laptop platforms will not accept these modules.

Build and daily handling

The kit uses major-brand chips without heat spreaders, so the bare PCB is exposed during installation and service. Standard 288-pin alignment applies and the unbuffered design means no register delay in the memory path.

Questions about this item

What comes in the 256GB kit and do I need any extra parts to install it?

The kit includes eight 32GB DDR4 3200 ECC UDIMM modules. No additional components are required; install them directly into your server or workstation’s 288-pin DDR4 slots.

How do I decide between the 2Rx8 dual-rank modules and other rank options?

These modules are 2Rx8 dual-rank x8. Choose this kit if your system supports dual-rank ECC UDIMMs and you need the full 256GB capacity across eight slots.

What does the PC4-25600 rating mean for real-world server performance?

PC4-25600 indicates a 3200 MT/s data rate at CL22 latency and 1.20V. In a compatible server it delivers 256GB of error-correcting memory bandwidth for virtualisation, databases and heavy multitasking.
