Server Memory Kit for Workstations and NAS

This OWC kit provides 256GB of DDR4 memory across eight 32GB modules. It is built for servers, workstations and NAS systems that require registered ECC RDIMMs. Standard desktop computers cannot use this memory and it must not be mixed with unbuffered modules.

Registered ECC with 2Rx4 Organisation

The decisive specification is the registered ECC design with a 2Rx4 rank configuration. This architecture allows the memory controller to address higher capacities per channel while correcting single-bit errors. Systems that expect unbuffered non-ECC DIMMs will not post with these modules installed.

Sustained Operation at 1.2V JEDEC Standard

Each module runs at the JEDEC-standard 1.2V and 2400MHz CL17 without overclocking headroom. Under continuous load the registered buffer reduces electrical loading on the memory bus, helping maintain signal integrity across all eight DIMMs in multi-channel configurations.

Questions sur cet article

What does the 256 GB capacity mean for a server workload?

The kit provides eight 32 GB registered ECC modules, giving a single system 256 GB of error-correcting memory for large datasets or virtualisation.

What does PC4-19200 indicate about the DDR4 2400 interface?

PC4-19200 is the JEDEC designation for DDR4 2400, confirming the modules run at 2400 MHz with CL17 latency at 1.2 V.

What physical slot and clearance do these 288-pin RDIMMs need?

Each module uses a standard 288-pin DDR4 RDIMM form factor with no heat spreader, so it fits any server or workstation board that accepts registered ECC DIMMs.
