OWC 64GB DDR3L ECC RDIMM kit

This 64GB kit contains four 16GB DDR3L 1600 PC3L-12800 CL11 registered DIMMs. It is built for HP ProLiant Gen8 servers and workstations that require ECC registered memory. Standard desktop computers cannot use these modules.

ECC registered operation

Error-correcting code and registered buffering protect data integrity in multi-socket server workloads. The 1.35V DDR3L voltage reduces power draw compared with standard DDR3. Modules cannot be mixed with unbuffered memory in the same system.

240-pin form factor for Gen8 bays

The 240-pin DDR3L RDIMMs install directly into the memory slots of HP ProLiant BL420c, BL460c, BL465c, BL660c and DL160 Gen8 platforms. No heat spreader is fitted, allowing dense blade configurations. This kit replaces HP part numbers 684316181, 688963001, 713756081, 713985B21, 713985B211 and 715284001.

Questions about this item

Will the 2Rx4 registered DIMMs need any firmware updates or matching modules if I add more later?

These are 2Rx4 registered ECC modules at 1.35V. Add only identical DDR3L 1600 CL11 2Rx4 RDIMMs; mixing ranks or buffered types will prevent the server from posting.

What limit appears first when the 64GB kit runs at 1600MHz continuously in a ProLiant Gen8?

The memory controller caps at DDR3L 1600 CL11. Sustained load hits the 1600 MT/s bandwidth ceiling before thermal limits, since the modules have no heat spreaders.

How much extra power and heat do the four 16GB sticks add compared with the original HP 1.5V DIMMs?

Each stick runs at 1.35V instead of 1.5V, lowering per-module draw. Total kit power stays within the ProLiant Gen8 DIMM slot budget, and airflow from the server fans handles the heat.
