Server Premier 32GB DDR4 ECC Registered

This 32GB DDR4-3200 module delivers registered ECC memory for servers and workstations that require error correction and signal buffering. It operates at 3200 MHz with CL22 timings and 1.20V voltage. The single-rank 1Rx4 organisation plugs into standard 288-pin DDR4 slots and includes an Intel XMP 2.0 profile for automatic configuration.

Upgrading from unbuffered or non-ECC DDR4

Systems running consumer-grade unbuffered memory without ECC can migrate to this registered module to gain data-integrity protection and reduced electrical load on the memory controller. The jump is worthwhile when workloads demand sustained uptime, large virtual-machine counts or database consistency that unbuffered memory cannot guarantee.

DDR4-3200 registered ECC constraints

Registered modules add a clock cycle of latency and require a motherboard with registered DIMM support; they will not function in consumer boards that only accept unbuffered memory. Mixing registered and unbuffered DIMMs is not supported, and the 3200 MHz speed will down-clock to the highest common speed the platform allows.

Questions about this item

Does the 288-pin DDR4 module fit standard server DIMM slots?

Yes, the 288-pin DDR4 form factor matches standard registered DIMM slots used in compatible servers and workstations.

Is any BIOS configuration needed to run the CL22 timings at 3200 MHz?

The module supports Intel XMP 2.0; enable the XMP profile in BIOS so the memory operates at the rated 3200 MHz speed with CL22 timings.

When should the 32 GB registered ECC module be replaced?

Replace the module if memory diagnostics report uncorrectable ECC errors or if the system shows repeated instability that testing isolates to this DIMM.
