Speed DDR3 1600 (PC3 12800)

  • 16GB quad-channel kit expands server memory capacity
  • CL11 latency at 1600 MHz speeds data access
  • ECC unbuffered design protects data integrity in workloads
  • Dual-rank 2Rx8 organisation increases memory density per slot
  • Standard 1.5V DDR3 voltage ensures broad platform compatibility

Server Memory Kit

This 16 GB DDR3 kit contains four 4 GB unbuffered ECC modules built for compatible servers and workstations. The dual-rank 2Rx8 organisation runs at 1600 MHz with CL11 latency at the standard 1.5 V. It is not suitable for desktop or laptop platforms.

Thermals and Power

Operating at the JEDEC 1.5 V level keeps power draw modest and heat output low in normal server workloads. Passive cooling from chassis airflow is sufficient for typical operation. No active cooling or additional voltage is required.

Sustained Load Behaviour

Under continuous heavy utilisation the modules maintain rated 1600 MHz speed and CL11 timing without throttling. ECC circuitry corrects single-bit errors throughout extended sessions to preserve data integrity in critical applications.

Questions about this item

How do I install the 240-pin DDR3 ECC UDIMM modules in the correct quad-channel order?

Insert each 4 GB module into the slots your motherboard manual designates for quad-channel operation, pressing straight down until the retention clips lock on both ends.

What maintenance will the 1.5 V DDR3 ECC UDIMM kit require over time?

No scheduled maintenance is needed; dust the slots with compressed air if the system runs in a dirty environment.

At what point does the CL11 latency become the bottleneck during sustained workloads?

The CAS latency of 11 cycles at 1600 MHz is fixed, so it limits random-access response before bandwidth saturates.
