32 GB DDR3 ECC kit for servers

This 32 GB kit contains eight 4 GB DDR3 1333 ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. Each module runs at 1.5 V and uses a 240-pin DIMM form factor with dual-rank x8 organisation. The kit is not compatible with standard desktop or laptop platforms.

Steady throughput with ECC protection

ECC circuitry detects and corrects single-bit errors during continuous operation, helping maintain data integrity under sustained workloads. Unbuffered signalling keeps latency low while the dual-rank layout allows the memory controller to interleave accesses across ranks. Rated CL9 timing at 1333 MHz provides consistent bandwidth for virtualisation, database and file-server tasks.

Major-brand chips on validated modules

Modules use major-brand DRAM components and undergo quality-assurance testing before shipment. The 240-pin DDR3 keying prevents accidental installation in incompatible slots, while the 1.5 V standard voltage matches existing DDR3 server power budgets. Eight modules fill all DIMM slots on many dual-socket boards, so verify channel population rules in the system manual before installing.

Questions about this item

How much power does each 4 GB DDR3 1333 module draw at 1.5 V during continuous server workloads?

Each module operates at the standard DDR3 voltage of 1.5 V; total kit capacity is 32 GB across eight 4 GB sticks.

What motherboard slot type and memory controller features are required to run this ECC UDIMM kit?

The kit uses 240-pin DDR3 DIMM slots and requires a server or workstation platform that supports unbuffered ECC memory.

Will these dual-rank 2Rx8 DDR3 1333 modules work in an older system that only accepts single-rank PC3-10600 DIMMs?

The modules are dual-rank 2Rx8 at DDR3 1333 (PC3-10600E); compatibility depends on whether the older system's memory controller supports dual-rank unbuffered ECC DIMMs.
