16GB DDR4 3200MHz ECC RDIMM

This 16GB registered DDR4 module runs at 3200MHz with CL22 latency and 1.20V operation. It targets servers and workstations that require error-correcting memory for data integrity. The dual-rank 2Rx8 organisation uses Samsung chipsets for broad platform compatibility.

Installation and common issues

The 288-pin DIMM inserts into standard DDR4 RDIMM slots and is keyed to prevent misalignment. Systems that accept only unbuffered UDIMMs will not recognise this registered module. Mixing registered and unbuffered DIMMs, or exceeding the platform's maximum rank count per channel, typically prevents boot.

DDR4 RDIMM practical limits

Registered DIMMs add a clock cycle of buffering that stabilises heavy memory loads but prevents use in consumer desktop chipsets lacking RDIMM support. ECC functionality requires a CPU and chipset that both implement the feature; otherwise the module operates as non-ECC registered memory. Maximum capacity per channel is defined by the platform's memory controller.

Preguntas sobre este artículo

How can I verify the A-Tech 16GB DDR4 3200MHz ECC RDIMM is running at CL22 and 1.20V after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 3200 MT/s, CAS latency 22, and 1.20 V for the installed module.

Does the A-Tech 16GB DDR4 3200MHz ECC RDIMM ship as a single 288-pin DIMM or do I need to buy additional modules?

The package contains one 16 GB 288-pin DDR4 RDIMM; order extra modules separately if your server requires more capacity.

Should I choose the 2Rx8 registered ECC version or a different rank configuration for my server?

Select this 2Rx8 registered ECC module when your platform specifies DDR4 3200 RDIMM with 2Rx8 organisation; other ranks or unbuffered types will not be compatible.
