Server ECC Upgrade Kit

This 16 GB kit contains four 4 GB DDR3 1600 MHz ECC unbuffered DIMMs built for servers and workstations. The modules run at 1.5 V with CL11 latency and use a single-rank x8 organisation. They are not compatible with standard desktop or laptop platforms.

Quad Channel Configuration

The four-module pack populates a quad-channel memory controller, widening the data path for multi-threaded workloads. ECC circuitry detects and corrects single-bit errors to protect data integrity in always-on environments. Major-brand chips are tested to meet the stated PC3-12800E specification.

16 GB Total Capacity

The kit delivers 16 GB of registered-style reliability in an unbuffered form factor, suited to virtualisation hosts, database nodes and compute clusters. Headroom ends when the platform's maximum supported memory or DIMM-slot count is reached, or when workloads demand higher frequencies than DDR3 1600 can provide.

Questions about this item

Will the 1Rx8 single-rank chips ever need individual replacement?

The four 4 GB modules are tested as a matched quad-channel kit; if one DIMM fails the whole kit is covered by the lifetime warranty.

Does the CL11 latency become a bottleneck during long compute runs?

CL11 is the rated timing at DDR3 1600; sustained workloads stay within that spec as long as the platform supports PC3-12800E.

How much heat do the 1.5 V unbuffered DIMMs produce under 24/7 load?

Standard 1.5 V DDR3 operation keeps thermals within JEDEC limits; normal server airflow is sufficient for continuous duty.
