  • Dual-rank 2Rx8 organisation maximises density per DIMM slot
  • Standard 1.5V operation matches DDR3 server platform requirements

64 GB DDR3 ECC UDIMM kit

This 64 GB kit contains eight 8 GB DDR3 1600 modules built for servers and workstations that require ECC unbuffered memory. Each 240-pin DIMM runs at 1.5 V with CL11 timing and a 2Rx8 dual-rank layout. The kit is not compatible with standard desktop or laptop platforms.

Thermals and power in normal use

Operating at the standard DDR3 voltage of 1.5 V, the modules draw typical power for this generation without needing active cooling. Passive airflow inside a server chassis keeps temperatures within specification during sustained workloads. Acoustic output is limited to the system fans already present.

What the bundled features change

ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. The unbuffered design reduces latency for supported platforms compared with registered alternatives. Major-brand DRAM chips and per-module testing aim to deliver consistent reliability across all eight sticks.

Questions about this item

How do I install the 240-pin DDR3 ECC UDIMM modules and what step is often missed?

Power off the server, open the chassis, align each 240-pin module with the DDR3 slot notch, press firmly until the retention clips click, then verify the BIOS recognises all 64 GB across the correct channels.

What maintenance or replacement will the 8 x 8 GB DDR3 kit need over time?

No scheduled maintenance is required; keep airways clear so the 1.5 V modules stay cool, and replace a stick only if memory diagnostics report errors.

What limit appears first when the 1600 MHz DDR3 ECC memory runs under sustained load?

The DDR3 1600 bandwidth ceiling and CL11 latency bound throughput before thermal limits become an issue.
