Server memory upgrade

This OWC kit provides 256GB of DDR4 2933 memory in two 128GB modules built for HP ProLiant Gen10 servers. The ECC Load Reduced DIMMs operate at 1.2V with CL21 latency and a 4Rx4 rank structure. They are intended for workloads that require large capacity and error correction in compatible server platforms.

Sustained load behaviour

Load Reduced technology reduces electrical load on the memory bus so the system can populate more slots without signal degradation. ECC corrects single-bit errors during continuous operation. Backward compatibility with 2133MHz, 2400MHz and 2666MHz allows the modules to run at lower speeds if the platform requires it.

Pre-order checks

Verify that your server model is listed: BL460c Gen10, DL325 Gen10, DL360 Gen10, DL380 Gen10 or DL385 Gen10. Confirm the platform supports DDR4 ECC LRDIMM and cannot mix these modules with unbuffered or registered ECC DIMMs. Check available 288-pin slots and maximum supported capacity per socket.

Perguntas sobre este artigo

How much power does the 1.2V DDR4 2933 LRDIMM draw when the server runs all day?

The modules operate at 1.2V, the standard DDR4 voltage, so power draw stays within normal server DIMM limits for continuous 24/7 workloads.

What must the HP ProLiant Gen10 already have to accept this 256GB 4Rx4 ECC Load Reduced kit?

The server must support DDR4 ECC Load Reduced DIMMs and have free 288-pin slots; it cannot mix these LRDIMMs with unbuffered or standard registered ECC modules.

Will these 2933MHz CL21 sticks down-clock reliably beside older 2133MHz or 2400MHz DIMMs I keep installed?

Yes, the kit is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds, so it will run at the lowest common frequency alongside existing modules.
