OWC 256GB (2x128GB) DDR4 2933 PC4-23400 CL21 4Rx4 288-pin 1.2V ECC Load Reduced DIMM memory upgrade

ECC Load-Reduced DDR4 for HP ProLiant Gen10

This 256 GB kit delivers two 128 GB DDR4 2933 LRDIMMs built for HP ProLiant DL560, DL580, DX360, DX380 and DX560 Gen10 servers. Each module runs at 1.2 V with CL21 latency and 4Rx4 organisation. The load-reduced design reduces electrical load on the memory bus, allowing higher density per channel in enterprise workloads.

Suited for memory-bound server roles.

The modules target virtualisation hosts, large databases and analytics clusters that need maximum capacity per slot. They will not work in standard desktop PCs, consumer workstations or any system that requires unbuffered or registered ECC DIMMs. Mixing with those types is unsupported and will prevent boot.

256 GB total with backward speed headroom

The kit provides 256 GB across two slots, leaving additional DIMM slots free for further expansion on supported platforms. Rated at 2933 MT/s, the memory also runs at 2666, 2400 and 2133 MT/s when paired with slower processors or bus limits. Capacity scales until the platform's maximum supported memory per socket is reached.
