Server-grade DDR5 upgrade kit

This 128 GB kit contains four 32 GB DDR5 4800 CL40 registered ECC RDIMMs built to JEDEC standard at 1.1 V. It is designed for HP ProLiant Gen11 servers including the DL325, DL345, DL360, DL365 and DL380 where registered memory is required.

Verify registered ECC requirement

Your system must accept 288-pin DDR5 registered ECC modules and cannot mix them with unbuffered or load-reduced DIMMs. Confirm the server has four available slots and that the BIOS is current before installation.

Low-voltage DDR5 thermals

Operating at 1.1 V, the modules run cool without heat spreaders in normal server airflow. Registered buffering adds minimal latency while maintaining signal integrity under sustained multi-threaded workloads.

商品問答

What comes in the 128GB kit and is anything else needed for installation?

The kit contains four 32GB DDR5 4800 CL40 2Rx8 288-pin 1.1V ECC Registered RDIMM modules. No additional parts are required for installation into compatible HP ProLiant Gen11 servers.

How do I choose between this 128GB kit and other capacities for my DL380 Gen11?

This kit provides 128GB total using four 32GB RDIMMs. Select it when your workload needs that capacity and your server has four available DDR5 slots. Other OWC kits offer different total capacities and module counts.

What does the DDR5 4800 CL40 rating mean once the modules are running in a DL360 Gen11?

The modules operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1V, delivering PC5-38400 bandwidth. The registered ECC design adds error correction and signal buffering for stable server operation.
