Server-grade ECC RDIMM kit

This OWC kit provides 256GB of DDR4 ECC registered memory across two 128GB modules. It targets servers, workstations and NAS systems that require registered DIMMs for data integrity. The dual-channel configuration supports high-capacity workloads in compatible multi-socket platforms. Standard desktop boards cannot use registered memory.

Verify registered DIMM support

Before ordering, confirm that your motherboard and CPU support DDR4 288-pin ECC registered RDIMMs. Registered modules will not function in platforms that accept only unbuffered memory. Check the system documentation for maximum capacity per slot and total population rules. Mixing registered and unbuffered DIMMs is not supported.

Low-profile modules for dense builds

Each module operates at 1.2V without a heat spreader, keeping the profile slim for tight server chassis. The 288-pin DDR4 interface is keyed to prevent mis-insertion. JEDEC compliance ensures electrical compatibility with qualified platforms. The bare PCB design eases installation in crowded DIMM arrays.

商品問答

What comes in the 256GB kit and do I need anything else to install it?

The kit contains two 128GB DDR4 2400 CL17 4Rx4 ECC registered RDIMMs. No extra parts are required; install them into compatible 288-pin server DIMM slots.

Should I choose this 256GB dual-channel kit or a different capacity for my server?

Select this 256GB (2x128GB) kit when your workload needs maximum registered ECC capacity per channel; choose a smaller kit only if your platform limits total memory or rank count.

What does the DDR4 2400 PC4-19200 rating mean once the modules are running in a server?

The modules transfer data at 2400 MT/s with CL17 latency at 1.2V, delivering 19200 MB/s peak bandwidth per module while providing registered ECC error correction for data integrity.
