  • 1Rx4 single-rank layout optimises signal integrity
  • 2 V standard voltage reduces power draw

128GB Quad-Channel ECC RDIMM Kit

This A-Tech kit supplies 128GB of DDR4 3200 registered ECC memory across four 32GB modules. It is built for servers and workstations that require error-correcting registered DIMMs. The single-rank 1Rx4 organisation and 1.20V operation match standard DDR4 server specifications. Desktop and laptop systems cannot use these modules.

Upgrade from lower-capacity or non-ECC memory

Replacing smaller RDIMM sets or unbuffered ECC modules with this quad-channel kit adds capacity and registered signal integrity for multi-socket platforms. The jump is worth it when workloads exceed current memory limits or when the platform demands registered DIMMs for stability. CL22 latency at 3200 MHz delivers standard DDR4 25600 throughput for supported server chipsets.

Suited for DDR4 server and workstation builders

Administrators expanding memory in compatible 288-pin DDR4 server platforms will benefit from the matched quad-channel configuration. Buyers needing unbuffered UDIMMs, desktop SO-DIMMs, or higher-speed registered modules beyond 3200 MHz should look elsewhere. Systems limited to lower maximum capacities per slot or non-ECC memory cannot use this kit.

Questions about this item

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

Yes, each 32 GB module uses the standard 288-pin DDR4 RDIMM form factor that fits server and workstation DIMM slots designed for registered ECC memory.

Do I need to populate all four slots in a specific order for the quad-channel kit to work?

Install the four modules in the channel pairs shown in your system manual; the common mistake is placing them in adjacent slots instead of the correct interleaved pattern.

How can I tell if a module has failed and needs replacing later?

ECC will log correctable errors in the system event log; rising correctable-error counts or uncorrectable errors indicate a module should be swapped out.
