Speed DDR3L 1333 (PC3L 10600)

  • 64 GB kit expands server capacity with eight 8 GB modules
  • DDR3L 1333 MHz speed accelerates data throughput for demanding workloads
  • ECC unbuffered design detects and corrects single-bit errors automatically
  • Dual-rank 2Rx8 organisation increases memory density per channel
  • 35 V low-voltage operation reduces power draw while remaining 1.5 V compatible

Server memory kit for DDR3 ECC platforms

This 64 GB kit contains eight 8 GB DDR3L unbuffered ECC UDIMMs rated at 1333 MHz with CL9 latency. It targets administrators upgrading compatible servers or workstations that require error-correcting memory for data-integrity workloads.

Fits 240-pin DDR3 slots running at 1.35 V or 1.5 V

Each module uses a 2Rx8 dual-rank organisation and major-brand chips. The kit occupies eight DIMM sockets, so the host system must provide enough slots and support unbuffered ECC memory at this voltage and speed.

Eight matched modules simplify population rules

The pre-tested kit removes the need to mix individual sticks and helps meet channel-balance requirements. A-Tech includes lifetime warranty coverage and US-based technical support for installation questions.

Questions about this item

What is the maximum voltage these modules can draw under sustained load?

The kit is rated for 1.35 V DDR3L operation and can also run at 1.5 V if the platform requires it.

How much heat or noise should I expect from the 8-module kit running continuously in a server chassis?

Unbuffered DDR3L DIMMs have no active cooling; they add negligible heat and zero noise, relying on the system's existing airflow.

Which motherboard feature must my server already support for this 240-pin ECC UDIMM kit to function?

The board must provide DDR3/DDR3L ECC unbuffered DIMM slots with 240-pin layout and dual-rank x8 support.
