128 GB quad-channel DDR4 kit

This 128 GB kit contains four 32 GB registered ECC DIMMs built for DDR4 servers and workstations. Each module runs at 3200 MHz with CL22 latency at 1.20 V. The dual-rank x4 organisation and 288-pin form factor match registered memory slots on qualified platforms.

Suited for registered DDR4 servers only

The modules require motherboards that support ECC RDIMM memory; they will not function in desktop or laptop systems that use unbuffered DIMMs. Buyers who need non-ECC or unregistered memory should look at a different product line.

2Rx4 registered ECC at 3200 MHz

The dual-rank x4 registered ECC configuration at 3200 MHz is the specification that determines whether the kit will be accepted by the target server or workstation. Verify the platform’s qualified-vendor list before purchase.

Questions about this item

Will the 128 GB quad-channel kit run alongside my existing DDR4 ECC RDIMM modules?

All modules operate at the standard DDR4 voltage of 1.20 V and use the same 288-pin RDIMM form factor, so they can share a server platform that supports mixed capacities and ranks.

How can I confirm the kit is running at 3200 MHz with CL22 timings after installation?

Check the memory speed and latency reported in the system BIOS or a hardware information utility; they should show DDR4 3200 (PC4-25600) and CAS latency 22 when the kit is configured correctly.

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

The package contains four 32 GB DDR4 3200 ECC RDIMM modules (2Rx4, 1.2 V) and nothing else; no additional components or cables are required for installation.
