8GB DDR4 ECC RDIMM for servers

This 8GB DDR4 2400 module adds ECC registered memory to compatible IBM-Lenovo servers and workstations. It runs at PC4-19200 speed with CL17 latency and 1.2V operation. The 1Rx4 organisation uses major-brand chips on a 288-pin DIMM for reliable multi-tasking in enterprise environments.

Replaces non-ECC or lower-capacity DIMMs

The jump is worth it when your workload demands error-correcting registered memory for data integrity. Systems currently running unbuffered or non-ECC modules at the same speed can migrate to this part for added stability. Buyers who need more than 8GB per slot or higher frequencies should verify platform limits before ordering.

DDR4 2400 registered interface limits

The registered buffer adds one cycle of latency compared with unbuffered DDR4 at the same clock. Maximum capacity per channel depends on the memory controller, not the module itself. Mixed populations of registered and unbuffered DIMMs are not supported on the same channel.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my server's memory slots?

This module uses the standard 288-pin DDR4 DIMM form factor. It fits server and workstation boards that accept registered ECC memory. Verify your system's qualified vendor list for the supported speed and rank configuration.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then confirm the system registers the full 8 GB at 2400 MHz in BIOS. A common error is stopping at the first click without fully engaging both clips.

When should this 1Rx4 module be replaced or serviced?

ECC RDIMMs have no moving parts and require no routine service. Replace a module only if your system logs uncorrectable memory errors or if a capacity upgrade is needed.
