8GB DDR3 ECC UDIMM kit

This A-Tech kit supplies 8 GB of DDR3 ECC unbuffered memory in two 4 GB modules. It is built for servers and workstations that require error-correcting DIMMs and will not fit or function in standard desktop or laptop platforms.

Sustained load behaviour

Each module operates at 1600 MHz with CL11 latency and 1.5 V, delivering steady throughput for long-running server workloads. The single-rank 1Rx8 organisation helps maintain consistent bandwidth across both channels during extended operations.

DDR3 interface limits

The DDR3 1600 standard caps module speed at 1600 MHz and peak transfer rate at PC3-12800. Systems that only support lower DDR3 speeds will downclock the kit, while platforms requiring registered or load-reduced DIMMs cannot use these unbuffered modules.

Questions about this item

How much power does the 1.5 V DDR3 1600 kit draw when the server runs all day?

The modules operate at the standard DDR3 voltage of 1.5 V, so power draw matches the JEDEC specification for 1.5 V DDR3 1600 UDIMMs under load.

What must my motherboard provide to use this 240-pin ECC UDIMM kit?

Your board needs DDR3 DIMM slots that accept unbuffered ECC modules and a chipset that supports ECC UDIMM operation.

Will the CL11 1Rx8 modules run alongside other DDR3 ECC DIMMs I keep installed?

Mixing ranks and speeds is possible if the motherboard trains all slots to a common speed and timing, but stability depends on the specific platform.
