256 GB DDR4 ECC RDIMM kit

This A-Tech kit delivers 256 GB of DDR4 server memory across eight 32 GB registered DIMMs. It is built for enterprise servers and workstations that require error-correcting, registered modules for stable operation under heavy workloads.

Registered ECC with 2Rx8 organisation

Each module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V. The dual-rank x8 layout and registered buffer ensure signal integrity on multi-DIMM channels, a requirement for most qualified server platforms.

Suits DDR4 RDIMM-only platforms

Buyers needing unbuffered UDIMM, LRDIMM or non-ECC memory for desktop or laptop systems cannot use this kit. Verify that your motherboard and CPU explicitly support DDR4 registered ECC DIMMs before ordering.

Questions about this item

What does the 3200 MHz rating mean once the modules are installed in a server?

The modules run at DDR4 3200 with CL22 latency and 1.20 V, delivering the rated bandwidth when the platform memory controller is set to that speed.

How does the PC4-25600 standard limit real-world throughput?

PC4-25600 defines the maximum transfer rate of 25600 MB/s per module; actual throughput depends on the server's memory controller and channel configuration.

What physical slot and clearance do the 288-pin RDIMMs need?

Each module is a 288-pin DDR4 RDIMM requiring a registered DIMM slot; verify the motherboard supports dual-rank 2Rx8 modules and follow the system manual for channel population.
