32 GB DDR4 ECC UDIMM for servers

This 32 GB DDR4 3200 MHz module is built for servers and workstations that require ECC unbuffered memory. It adds capacity to systems handling virtualisation, databases or heavy multitasking workloads. The dual-rank 2Rx8 organisation helps maximise bandwidth on supported platforms. Buyers needing error-correcting memory for data integrity will find this module suitable.

Verify DDR4 ECC UDIMM support first

Check that your server or workstation accepts DDR4 ECC unbuffered DIMMs before ordering; desktop and laptop platforms are not compatible. Confirm the motherboard supports 288-pin DIMMs at 3200 MHz and can address 32 GB per slot. Consult the system manual for approved memory configurations, channel population rules and maximum capacity per channel. Mixing ranks or speeds may prevent the module from operating correctly.

Standard voltage and tested reliability

The module runs at the standard 1.2 V DDR4 voltage, keeping power draw within normal limits for registered server memory. All units undergo quality-assurance testing to ensure stable operation under sustained loads. Typical server airflow keeps temperatures in check without additional cooling requirements. Acoustic output is negligible as the module has no moving parts.

Questions about this item

What comes in the box and do I need anything else to install this 32GB DDR4 3200 ECC UDIMM?

The box contains one 32GB DDR4 3200 ECC UDIMM module rated CL22 at 1.2V with 288 pins. No extra parts are required if your server or workstation has a free DDR4 ECC UDIMM slot.

How do I decide between the PC4-25600 and PC4-3200AA-E speed labels on this module?

Both labels describe the same 3200 MHz DDR4 specification; choose the module if your system supports DDR4 3200 ECC UDIMM and you need a single 32GB dual-rank stick.

What does the CL22 latency mean for real-world server workloads with this 32GB stick?

CL22 indicates 22 clock cycles of CAS latency at 3200 MHz, giving standard DDR4 timing for ECC UDIMM tasks such as virtualisation, databases and multi-threaded compute.
