Target Server Memory

This 8GB DDR3 1866 ECC UDIMM module is built for servers and workstations that require unbuffered error-correcting memory. It operates at 1.5V standard voltage with a CL13 latency and a 2Rx8 dual-rank organisation. The 240-pin DIMM fits only platforms designed for DDR3 ECC unbuffered memory.

ECC And Rank Benefits

Error-correcting code detects and corrects single-bit errors to protect data integrity in critical workloads. The dual-rank x8 layout increases memory density per slot, allowing higher total capacity within the same number of DIMM sockets. Unbuffered design keeps latency low for compatible platforms.

Capacity And Limits

The single 8GB module handles typical virtualisation, database and file-server tasks with room for moderate multitasking. Workloads that demand larger datasets or many concurrent virtual machines will exhaust this capacity quickly. Systems limited to low maximum memory per channel cannot scale beyond a few modules.

Questions about this item

Will the ECC UDIMM chips or the 240-pin gold contacts need replacement after years of continuous server operation?

The module uses major-brand DRAM chips tested for long-term reliability; under normal server conditions the chips and contacts do not wear out and no scheduled replacement is required.

What limit appears first when this 1866 MHz CL13 module runs sustained workloads — bandwidth, latency or thermal throttling?

The JEDEC-standard 1.5 V DDR3 design and unbuffered topology mean thermal throttling is not a factor; the first limit you reach is the rated 1866 MHz bandwidth ceiling.

How much heat and power does a single 1.5 V 8 GB stick add when the server runs all day?

At the standard 1.5 V DDR3 voltage the module draws only a few watts and adds minimal heat, well within typical server airflow limits for 240-pin UDIMM slots.
