Server & Workstation DDR4 Kit

This A-Tech 32GB kit contains four 8GB DDR4 2933 ECC UDIMM modules built for servers and workstations. Each stick runs at 1.20V with a CL21 latency and a single-rank 1Rx8 layout. The 288-pin unbuffered design fits compatible DDR4 platforms that require error-correcting memory. It is not suitable for standard desktop or laptop computers.

Sustained-Load Behaviour

The quad-channel configuration spreads traffic across four modules to keep bandwidth steady during long-running workloads. ECC circuitry detects and corrects single-bit errors on the fly, preventing data corruption that can accumulate over hours of continuous operation. Major-brand chips and factory testing aim to deliver consistent throughput without throttling. Single-rank organisation helps maintain predictable timing under heavy multi-threaded demand.

Thermals Noise & Power

Operating at the standard 1.20V DDR4 voltage keeps power draw low and reduces heat output inside dense chassis. No heat spreaders are fitted, so airflow from system fans passes directly over the DRAM packages. The modules run silently because they have no moving parts or active cooling. Low thermal contribution helps maintain stable temperatures in packed server enclosures.

Questions about this item

How much power does this quad-channel 32GB DDR4 2933 kit draw at its rated 1.20V when running continuously?

Each 8GB module operates at the standard DDR4 voltage of 1.20V; total system draw depends on your server's memory controller and workload.

What must the motherboard provide to run this ECC UDIMM kit at 2933 MHz CL21?

The board must support DDR4 ECC unbuffered DIMMs, 288-pin slots, quad-channel architecture, and be able to run at 2933 MHz with CL21 timings at 1.20V.

Will these single-rank 1Rx8 DDR4 2933 modules work in the same server as existing DDR4 ECC UDIMMs of a different speed?

Mixed-speed DDR4 ECC UDIMMs will usually run at the lowest common speed; check your system manual for supported mixed-rank and mixed-speed configurations.
