Targeted Server Upgrade

This 1 TB kit contains eight 128 GB DDR5 4800 CL40 4Rx4 registered ECC RDIMMs built for HP ProLiant Gen11 servers. It suits administrators who need maximum registered ECC capacity in DL325, DL345, DL360, DL365 or DL380 platforms. The modules will not work in standard desktops or with unbuffered or load-reduced memory. Buyers who need a different form factor or non-ECC memory should look elsewhere.

Sustained Load Behaviour

JEDEC-standard 1.1 V operation keeps power draw predictable during long compute runs. Registered buffering and on-die ECC maintain data integrity across all 288 pins when every slot is populated. The CL40 latency is fixed by the DDR5 4800 specification, so throughput remains consistent under continuous multi-threaded workloads. No heat spreader is fitted, so airflow through the chassis determines thermal stability.

Build And Connector Implications

Each module uses a standard 288-pin DDR5 RDIMM edge connector that seats directly in the server's memory slots. The lack of a heat spreader reduces height, aiding fitment in dense 1U or 2U chassis where clearance is tight. Eight modules fill the full channel set on supported Gen11 systems, so installation order follows the platform's documented population rules. The kit is RoHS compliant and covered by OWC's limited lifetime warranty with advanced replacement.

商品問答

How much power does the 1.1V DDR5 4800 kit draw when the server runs continuously?

Each module operates at 1.1V, the standard JEDEC voltage for DDR5 4800. Total system draw depends on the platform power management and how many of the eight DIMM slots are populated.

Which HP ProLiant Gen11 server must the buyer already own for this 288-pin ECC RDIMM kit to work?

The kit is validated for HP ProLiant DL325 Gen11, DL345 Gen11, DL360 Gen11, DL365 Gen11 and DL380 Gen11. The motherboard must support DDR5 4800 registered ECC 4Rx4 DIMMs.

Can the 4Rx4 CL40 DDR5 4800 modules share channels with lower-rank DDR5 DIMMs the buyer keeps?

The manufacturer states these registered ECC modules cannot be mixed with unbuffered or load-reduced ECC memory. Mixing different rank configurations on the same channel is not supported.
