Server ECC Kit

This 8 GB kit contains two 4 GB DDR3 1866 ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. It runs at the standard 1.5 V and uses a dual-rank x8 organisation with CL13 timing. The kit is not compatible with desktop or laptop platforms.

Straightforward Installation

Each 240-pin DIMM seats in a standard DDR3 UDIMM slot without extra cabling or tools. The most common issue is installing the kit in a system that only accepts registered ECC or non-ECC memory, which prevents the machine from posting. Always confirm the motherboard supports unbuffered ECC before fitting the modules.

Steady Workload Behaviour

Under sustained server loads the ECC function continuously detects and corrects single-bit errors, keeping data integrity intact during long compute jobs or virtualisation tasks. The 1.5 V operation maintains stable power draw across extended periods, and the dual-channel layout helps sustain throughput when all channels are populated.

Questions about this item

How can I confirm the kit is running at DDR3 1866 CL13 after installation?

Check the BIOS or a tool such as CPU-Z; each module should report 1866 MHz speed, CL13 latency, 1.5 V voltage and ECC unbuffered operation.

What is included in the package and do I need anything extra?

The box contains two 4 GB DDR3 ECC UDIMM modules (2Rx8, 240-pin); no extra parts are required if your server or workstation supports DDR3 ECC unbuffered memory.

Should I choose the 8 GB dual-channel kit or a different capacity?

This 8 GB (2×4 GB) dual-channel kit is the only capacity offered here; select it when your system needs an 8 GB matched pair of DDR3 1866 ECC UDIMM modules.
