64GB DDR3L ECC Registered kit

This 64GB kit contains four 16GB DDR3L 1600 PC3L-12800 CL11 registered DIMMs built to 1.35V JEDEC specifications. The 240-pin modules carry ECC and a 2Rx4 organisation for error-correcting server workloads. They are validated for HP ProLiant DL360e Gen8, DL360p Gen8, DL380p Gen8, DL385p Gen8 and DL580 Gen8 systems.

Suited for Gen8 ProLiant upgrades.

Administrators extending the service life of the listed Gen8 rackmount servers will find a direct replacement for HP part numbers such as 713985B21 and 684316181. Builders of standard desktop PCs or consumer workstations cannot use registered ECC DIMMs, and the modules cannot be mixed with unbuffered memory in any platform.

Registered ECC with 2Rx4 organisation

The registered buffer and on-die ECC are the single specification that decides compatibility; only systems designed for registered DDR3L ECC RDIMMs will accept this kit. Attempting installation in an unbuffered-only motherboard will result in a no-post condition.

Questions about this item

Can the 16 GB DDR3L RDIMMs run alongside existing 8 GB DDR3L RDIMMs in my DL380p Gen8?

Yes — both use 240-pin DDR3L 1600 registered ECC at 1.35 V, so they share the same electrical and timing spec; just populate matching channels per the server manual.

How do I confirm the 64 GB kit is detected at 1600 MHz with ECC active after installation?

Enter the BIOS or iLO interface; the memory summary should show 64 GB total, 1600 MT/s speed and ECC enabled for each of the four 16 GB 2Rx4 modules.

Does the box contain only the four 16 GB modules, or are any tools or cables included?

Only the four 240-pin DDR3L 1600 CL11 1.35 V ECC registered RDIMMs are supplied; no tools, cables or brackets are provided.
