16GB DDR3L ECC RDIMM kit

This kit supplies 16 GB of DDR3L 1600 registered ECC memory in two 8 GB modules. It is built for HP ProLiant Gen8 servers including the DL360e, DL360p, DL380p, DL385p and DL580. The modules will not work in standard desktop computers or alongside unbuffered DIMMs.

Sustained server workloads

Registered buffering and ECC correction keep data integrity stable during continuous operation in virtualization, database or NAS roles. CL11 latency at 1.35 V delivers consistent throughput without the voltage headroom required by standard DDR3. The dual-rank 1Rx4 organisation supports high-density population on supported ProLiant platforms.

240-pin registered form factor

Each module uses the 240-pin DDR3L RDIMM form factor with no heat spreader, allowing tight spacing in factory drive cages. The kit replaces HP part numbers 731765B21, 731765B211 and 735302001 for direct drop-in upgrades. Buyers needing unbuffered memory or consumer desktop compatibility should choose a different product.

Questions about this item

How much heat does the 1.35V DDR3L kit generate when the server runs continuously?

The 1.35V DDR3L modules draw less power than standard 1.5V DDR3, reducing thermal output during 24/7 operation. No heat spreader is fitted, so airflow across the 240-pin DIMMs handles cooling.

Which HP ProLiant Gen8 models must the buyer already own for this 2 x 8GB kit to work?

The kit is validated for HP ProLiant DL360e Gen8, DL360p Gen8, DL380p Gen8, DL385p Gen8 and DL580 Gen8. It replaces HP part numbers 731765B21, 731765B211 and 735302001.

Can the CL11 ECC registered DIMMs sit alongside older unbuffered DDR3 sticks already in the server?

No. Registered ECC modules cannot be mixed with unbuffered memory; the memory controller requires all populated slots to use the same registered topology.
