Speed DDR3L 1600 (PC3L 12800)

  • 64 GB kit expands server capacity for heavy workloads
  • DDR3L 1600 MHz speed accelerates data throughput
  • ECC unbuffered design detects and corrects memory errors
  • 35 V low-voltage operation reduces power draw
  • 240-pin dual-rank modules fit compatible DDR3 server slots

Server memory kit for DDR3 platforms

This 64 GB kit contains eight 8 GB DDR3L 1600 ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. It is not compatible with desktop or laptop computers that use non-ECC or registered DIMMs.

Dual-rank x8 organisation with low-voltage operation

Each module uses a 2Rx8 layout and runs at 1.35 V, with the ability to operate at 1.5 V when the platform demands it. The ECC function corrects single-bit errors to protect data integrity in critical workloads.

Straightforward DIMM installation with channel rules

The 240-pin DIMMs install in the usual way, but the system manual must be followed for correct slot population and channel guidelines. Mixing ranks or voltages without verification is the most common cause of boot failure.

Questions about this item

Will the 2Rx8 dual-rank modules require any firmware updates or reconfiguration when I add all eight to my server?

The kit uses standard 2Rx8 DDR3L ECC UDIMM modules at 1600 MHz with CL11 latency; installation follows your system's manual for seating and channel population, and no firmware step is mentioned in the specifications.

What limit appears first when the 64 GB kit runs at 1600 MHz continuously under full load?

The modules operate at 1.35 V with a CL11 timing at 1600 MHz; sustained throughput is bounded by the DDR3L 12800 data rate and the unbuffered dual-rank topology.

How much heat and power draw should I expect from the eight 1.35 V DIMMs running all day?

Each module is rated at 1.35 V (compatible with 1.5 V) and uses major-brand chips; total power scales with the 64 GB capacity at DDR3L voltage, and no additional cooling beyond normal server airflow is specified.
