Server-grade ECC registered kit

This OWC kit delivers 256 GB of DDR4 ECC registered memory in four 64 GB modules. It is built for HP Apollo 4200 Gen10 and 6500 Gen10 servers and workstations that require registered DIMMs with error correction. The modules will not work in standard desktop PCs or in systems that use unbuffered or load-reduced memory.

DDR4 2933 registered interface limits

The modules run at 2933 MT/s with CL21 latency at 1.2 V and conform to the PC4-23400 standard. They are backward compatible with 2133, 2400 and 2666 MT/s bus speeds, so they will clock down automatically when the platform requires it. Registered signalling adds one cycle of command delay, which is mandatory for the supported Apollo platforms.

256 GB capacity for dense workloads

Four 64 GB 2Rx4 DIMMs fill four slots and provide the maximum supported density per module for these Apollo systems. The kit suits virtualisation, large databases and high-thread-count compute where memory capacity is the primary bottleneck. Systems that need more than 256 GB per socket or that only accept unbuffered DIMMs cannot use this kit.

Domande su questo articolo

Should I choose the 256 GB kit with four 64 GB modules or a smaller capacity?

The kit provides 256 GB total across four 64 GB modules, matching the maximum supported configuration for the HP Apollo 4200 Gen10 and 6500 Gen10 servers.

What does the 2933 MHz rating deliver in my server?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency, and will down-clock to 2666, 2400 or 2133 MHz if the platform requires a lower speed.

Is the 288-pin ECC registered interface compatible with standard desktop boards?

No — these are 288-pin DDR4 ECC registered DIMMs designed for server and workstation platforms only; they will not work in unbuffered desktop motherboards.
