OWC 1TB DDR4 3200 ECC LRDIMM kit

This OWC memory kit provides 1TB of DDR4 3200 ECC Load Reduced DIMM capacity across eight 128GB modules. It is built for the HP Apollo 4200 Gen10 Plus server and operates at 1.2V with CL22 latency. The 288-pin 4Rx4 LRDIMM design reduces electrical load on the memory bus for high-density configurations.

Suitable for server and workstation upgrades

This kit suits administrators expanding an HP Apollo 4200 Gen10 Plus with validated ECC LRDIMM modules. It will not work in standard desktop computers or consumer motherboards. It cannot be mixed with unbuffered or standard registered ECC DIMMs. Buyers needing non-ECC memory or desktop form factors should look elsewhere.

288-pin DDR4 3200 ECC Load Reduced specification

The decisive specification is the 288-pin DDR4 3200 ECC Load Reduced LRDIMM form factor with 4Rx4 organisation. Only systems qualified for this exact module type will accept the kit. The modules are backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds.

Questions about this item

How does the 1TB (8 x 128GB) capacity translate once installed in an HP Apollo 4200 Gen10 Plus?

The kit fills eight DIMM slots with 128GB LRDIMMs each, giving the server a total of 1TB of ECC load-reduced memory for large workloads.

What does the PC4-25600 rating mean for usable speed in this server?

The modules run at DDR4 3200 with CL22 latency; the Apollo 4200 Gen10 Plus will operate them at up to 3200 MT/s and can also run them at 2933, 2666, 2400 or 2133 MT/s if the system requires a lower speed.

What physical slot and form factor do these modules need to fit the Apollo 4200 Gen10 Plus?

Each module is a 288-pin DDR4 LRDIMM; the kit provides eight sticks that install directly into the server's 288-pin DIMM slots.
