Four green DDR3 ECC UDIMM sticks, 240-pin, matte black chips

A-Tech

A-Tech 16GB (4x4GB) DDR3 1866 ECC UDIMM 2Rx8 1.5V Server RAM

SKU CH-2RDR-WR3ZF

A 16 GB quad-channel DDR3 kit with four 4 GB ECC unbuffered DIMMs running at 1866 MHz CL13 and 1.5 V for compatible servers and workstations

  • Capacity16GB (4 x 4GB)
  • SpeedDDR3 1866 (PC3 14900)
  • CAS LatencyCL13
  • Voltage1.50V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 16GB (4 x 4GB)

  • 16 GB quad-channel kit expands server memory capacity
  • 1866 MHz DDR3 speed accelerates data throughput
  • CL13 CAS latency sharpens response times
  • ECC unbuffered design protects data integrity
  • 5 V standard voltage ensures broad compatibility

Kit Composition

This kit provides 16GB of DDR3 memory across four 4GB modules, designed for servers and workstations that require ECC unbuffered DIMMs. It targets administrators expanding capacity on platforms that support DDR3 1866 ECC UDIMM memory.

Build Integration

The 240-pin DIMMs install in quad-channel configurations on compatible server or workstation motherboards that accept unbuffered ECC DDR3. ECC functionality protects data integrity, while the unbuffered design suits platforms that do not use registered modules. Verify your system manual for supported memory specifications and channel population rules before installation.

Sustained Operation

Rated at DDR3 1866 with CL13 latency and 1.5V operation, the modules maintain stable throughput during continuous workloads such as virtualization, database serving, or compute clusters. Dual-rank 2Rx8 organisation and major-brand chips help sustain bandwidth under load, while ECC correction reduces error-related interruptions over long run times.

Questions sur cet article

Does the CAS latency of CL13 limit throughput when the server runs at full load for hours?

CL13 is the rated timing at DDR3 1866; the modules operate at that latency continuously as long as the system keeps them at 1.5 V and within thermal limits.

How much heat and power should I expect from four dual-rank 4 GB sticks running 24/7?

Each stick runs at the standard DDR3 voltage of 1.5 V; total draw scales with all four modules active, and typical server airflow handles the resulting heat without extra cooling.

My board has 240-pin DDR3 slots — is that the only requirement for this quad-channel kit to work?

The board must support DDR3 ECC unbuffered DIMMs at 1866 MHz and accept dual-rank x8 modules; desktop or laptop platforms will not work even if the slot fits.
