OWC 64GB (4x16GB) DDR4 2400 CL17 ECC UDIMM desktop RAM

ECC UDIMM Kit for Workstations

This 64GB kit contains four 16GB DDR4 2400 CL17 modules that run at 1.2V on a 288-pin unbuffered layout. ECC protection detects and corrects single-bit errors, making the kit suitable for workstations, servers and NAS systems where data integrity matters. The dual-rank 2Rx8 organisation helps populate four slots efficiently while keeping within JEDEC standard specifications.

Upgrade from 2133MHz or Non-ECC Memory

The modules are backward compatible with 2133MHz platforms, so they can replace slower DDR4 without a platform change. Moving to 2400MHz CL17 adds bandwidth for multi-threaded workloads and the ECC feature adds error correction that standard UDIMMs lack. The jump is worth it when your applications run long calculations or hold large datasets in memory and cannot tolerate silent corruption.

Steady Throughput Under Sustained Load

Rated at PC4-19200, the kit delivers consistent transfer rates during extended compile, virtualization or ZFS scrub sessions rather than only in short bursts. Unbuffered design keeps latency low while the 1.2V operating point limits thermal output inside dense chassis. JEDEC compliance ensures the modules settle at rated timings without manual tuning, so performance remains stable across reboots and temperature cycles.
