Server DDR4 3200 ECC RDIMM

This module is a single 256GB DDR4 3200MHz PC4-25600 registered DIMM with ECC. It is built for servers and workstations that require registered memory with error correction. It is not for standard desktop or laptop computers that use unbuffered non-ECC modules.

Installing registered ECC memory

Insert the 288-pin module into a compatible DDR4 RDIMM slot with the system powered off. The 8Rx4 organisation and 1.2V operation are handled by the memory controller; no manual voltage adjustment is needed. Mixing registered and unbuffered DIMMs or using this module in a non-ECC platform will prevent boot.

Verify platform compatibility first

Confirm that your motherboard and CPU support DDR4 3200MHz registered ECC RDIMMs and can address 8Rx4 density per module. Check the qualified vendor list for 256GB single-module capacity and CAS latency 22 timing. Systems limited to unbuffered memory or lower maximum module density cannot use this kit.

Questions about this item

How can I confirm the 256GB DDR4 3200MHz module is running at the correct 3200MHz speed after installation?

Enter the server BIOS or use a tool like CPU-Z to verify the memory frequency reads 3200MHz and the CAS latency shows 22 at 1.2V.

What is included in the box and do I need any extra brackets or cables for a standard 288-pin server DIMM slot?

The box contains the single 256GB 8Rx4 ECC RDIMM only; no additional brackets, cables or heatsinks are required for a standard 288-pin registered DIMM slot.

Should I choose the 256GB 8Rx4 version or a lower-capacity 1Rx4 or 2Rx4 module for my DDR4 3200MHz server?

Select the 256GB 8Rx4 module when the platform supports 8-rank registered DIMMs and you need maximum density per slot; otherwise choose a lower-rank module that matches your motherboard's rank limit.
