Capacity and form factor

This is a single 128 GB DDR5 registered DIMM built for server platforms that require ECC memory. The module runs at 4800 MT/s with a CAS latency of 40 and operates at 1.1 V.

Installation notes

The 288-pin RDIMM fits standard DDR5 server slots and the registered design helps signal integrity on heavily populated boards. Mixing ranks or voltages can prevent the system from posting, so verify the motherboard qualification list before adding this stick.

Who should buy

Ideal for administrators expanding memory in compatible DDR5 servers that need high-density ECC registered modules. Not suitable for desktop PCs, workstations that require unbuffered memory, or systems limited to lower-capacity DIMMs.

Questions about this item

How can I confirm the module is running at 4800MHz after installation?

Enter the server BIOS or use a hardware monitoring tool to verify the memory speed reads 4800MHz and CAS latency shows 40.

What ships in the box and do I need any extra parts?

The kit contains one 128GB DDR5 4800MHz 2Rx4 ECC RDIMM. No additional components are required for installation in a compatible server.

Should I choose the 1Rx128GB or 2Rx4 version for my server?

This module is a 2Rx4 configuration. Select it when your server's memory population rules call for dual-rank x4 organisation.
