Speed DDR3L 1333 (PC3L 10600)

  • 64 GB total capacity across four 16 GB modules
  • DDR3L 1333 MHz speed with CL9 latency for responsive server workloads
  • ECC registered design detects and corrects memory errors
  • Low-voltage 1.35 V operation reduces power draw and heat
  • 240-pin dual-rank x4 configuration fits DDR3/DDR3L server slots

64GB DDR3L ECC RDIMM kit

This 64GB kit contains four 16GB DDR3L 1333 MHz registered ECC modules built for servers and workstations. The dual-rank x4 design and CL9 latency deliver reliable throughput for multi-threaded workloads. It operates at 1.35V and can also run at 1.5V where the platform requires it. The 240-pin form factor fits DDR3/DDR3L registered DIMM slots only.

Replaces lower-capacity DDR3 registered kits

Upgrading from smaller registered DDR3 sets is worthwhile when virtualisation hosts, database servers or compute nodes hit memory pressure and swap activity rises. The quad-channel population fills four slots at once, matching the channel architecture of compatible platforms. It is not suitable for desktop or laptop systems that use unbuffered non-ECC memory.

64GB capacity with quad-channel headroom

The 64GB total handles large virtual-machine fleets, in-memory databases and heavy compilation jobs without paging. Headroom remains until the platform's maximum registered DIMM limit or slot count is reached. Beyond that point, a move to a newer memory generation and CPU platform would be required.

Questions about this item

Will the 240-pin DDR3/DDR3L RDIMMs fit my server's memory slots?

These are 240-pin DDR3/DDR3L Registered DIMMs; they fit only server or workstation boards that accept DDR3 RDIMMs, not desktop or laptop slots.

How do I install the quad-channel kit correctly?

Populate all four 16 GB modules in the matching channel slots shown in your system manual; the common mistake is mixing channels or leaving a slot empty.

When should I replace the 1.35 V DDR3L modules?

Replace a module if memtest or your server's ECC logs report uncorrectable errors; otherwise DDR3L RDIMMs typically run for the life of the platform.
